I have a question here guys...the manual says to "increase" the suspension settings for "higher speed" operation.This means according to the little graphs in there,that everything needs to be turned clockwise.Okay....that's not what I'm really wondering.I want to know....does anyone here ever experience any "higher speed" weave going on while cornering?I'm not talking about wiggle.And it's not the tire slipping either.It feels like it may be coming from the rear wheel/suspension action.It is not bouncing when it does this.Not that I can feel.Just wondering if this is a normal behavior of strong fast sportbikes?I am not increasing or decreasing throttle while this is happening.Ocassionally,it will feel "kind of" more "noticeable"....but stops if I ease up on the throttle.I can not tell if my body position has any effect on it....but there are certain times when I adjust my riding position while coming into or cutting the apex where the bike feels excellently stable no matter what.IDK if it's the road,my body position,or suspension that's starting it.It certainly isn't consistent.Just kinda happens sometimes at higher speed turns.It's very quick,maybe around a 60 or 70 foot length depending on where and when it starts happening and is NOT a tankslapper getting ready to happen(I don't think anyway).The frontend feels fine while this is going on.It doesn't last but a second or two.Enough to get my attention anyway.

You see this same thing when the GP guys are accelerating out of a curve...kinda.The chassis will move off center.I don't know if this is the same thing.I don't make a habit of gassing my bike coming out of curves at higher speeds.My weight is usually forward over the engine and I'm usually leaned off to the inside edge pretty much,but not like the race guys...not that extreme.It's hard to duplicate the conditions when yer out on the open road...going somewhere,and every turn is different.

The manual does not say what "high speed operation" is....so I really can't tell if my speeds would be classed that way for this bike,or what."rough road,high speed"...okay....I'm 175....My suspension settings now are NOT factory.Everything has been firmed up...including all damping adjustments.

Darn, the BBcode bar isn't displaying this morning, so no easy Quote etc.

I'm not sure what behavior you are talking about, Blue. Its hard to explain a complex behavior in writing, isn't it? If we could stand on the inside and outside of a corner and film you, we would possibly see whats happening.

I will say though, that based on the vids you posted, you are probably finding, or close to, the limits of this motorcycle, as far as high speed sweepers go.

That "weave" might just be the motorcycle trying to tell you that its approaching its limit, beyond which you don't want to go.

The manual does not say what "high speed operation" is...

You ha roudies don't read well, do you or you must ha read like ha dis. 'Hi ha have ha my balls set at this speed, I have ha test rider here is show you how is your speed an his ha speeda reading ha close the book. We try ha dis ha way operation on the frontal lobe. You ha now ha see, little sea weed?

...so I really can't tell if my speeds would be classed that way for this bike,or what

. Well, if you can't describe it on the net, in the newspaper, over the phone, what the fuck did you start a thread on it then?

"rough road,high speed"...okay....I'm 175....My suspension settings now are NOT factory.Everything has been firmed up...including all damping adjustments.

Are you zipping in another zone? Wobble cranked over? Waa-waa-was the back wheel coming around kind of pulsating? Not really there to match a line and see it wobble next to it? That kind of chassis upset?

1. You are going to find out soon enough. Are we a squiddy mid packer? Fresh rear, old front, let's skate it in the corner there goes the front end? Come clean or you will chase your tail. This is like the penultimate question on tire.
A. Yes did we check compression or are you now chasing tail the donkey yo, penultimate first question out of the box. Are we on fresh fronthe rear too, or are we on old/new combo, yes, I am an idiot, I don't see equal wear they both roll equally worn is yes is my answer and it is me who stands in front of hubs fish market reading that menu, I'll bring the dog with the chick wingading-ding!
B. No. Not in my pit.

2. Tire pressure low?

3. Swing arm pivot: Unhook the one bolt to swing the arm in the X to Y moves. Any ratchet feel like dirty needle bearings. Y-move is push back and forth to see if a cage is collapsing. This will have a little movement to the obvious click or some sort of play. And you do not want any play but that tight tolerance without the movement.

4. Drive chain Whaa-Whaa: Something like a hi/low rung? I'm hardcore tech in your face so you go find some chain video of mine; go find Wha-waaaaaaaaa??? That puppy does the waa anyway I would think. Not really a perfect rear end drive like a ring/pinion kind of tight on lift and more precision in the X to Y, don't you think?
A. Chain has to run zero-wha. If we are looking for some sort of high speed wobble, are we heading in the right direction? I can't tell what your wiggle is?
B. Tight is more like the oil threads. You know the shift quality counts on the chain or you'll be missing gears.

5. Harmonic Ride: You crying about your man card? If all the above are in line with the stars kind of drive line, are we cranking it like the book says? Bring on your test rider?

Geez Hub...I actually thought I explained pretty well.I DON'T KNOW WHAT THE JAPANESE WOULD CONSIDER HIGH SPEED OPERATION.That's all.They don't give any examples...you know,like saying..."if you're going 140,and a 150 lb rider...this is considered High Speed riding".To them...high speed riding MIGHT be 80 mph...who knows.That's my point.The bike WILL perform differently with certain settings at certain speeds.I'm asking....does anyone have any experience with what I'm talking about...and what did they do?Kinda straightforward...not a mystery at all.Surely SOMEONE here has experienced this type of chassis movement while leaned over in a curve at OVER speed limit values.

Anyway...I'm just gonna do some adjustments and see what happens.I know...and this MIGHT help someone else down the road...when I lowered my bike 1" front and back,this behavior was VERY pronounced at anything around 85 mph.I tightened all the adjustments down as far as I almost could,and it kept the thing at bay until I hit around 120.I could not adjust any tighter...I didn't want to be riding a bike that felt like the suspension was...well... non-existent.That in itself tells me it's not my tires.I'll continue to experiment with this.It's not like SEVERE or anything.It does feel like it's "wallowing"....kinda.That would be rear suspension too soft.Gonna spend today trying some different settings.See what I can come up with.

I was geezering you, blue. I know what you mean when your cooking it in a corner. It goes like this. These are just piles of wheels and an hinge. Quit crying about some bike going to gyro on you with the engine pulses, the gyro effect, your compression; the compression on the bike, the japanese have to walk that stupid ass tight line about what is fast and what the fuck you fasting for?

You want me to punch your wallow ticket? It's a fucking spring! Shut the fuck up, ride piss out of it and quit pissing about finding perfect settings with production shitstaints on the seat WOThat puppy UP and shut the fuCUP! You do understand you are pushing the puppy and it is talking back?

Smack it or yell at it. Last thing you want to do is back off of the gas. Oh, but you were not crying then, were you. You were having more fun than the average 14 rider you suck change get out and play. I haven't touched the sag since I stripped all of it off. Ride the wheels off it, or buck up on some suspension. I just don't think about that shit when it happens.

Either ride the bike or give me that yes or no I'm waiting for. You're stalling.

Yes, I'm a old/new tire biter.
No, you won't catch me in office whipping my dick all around here ladies!

Ride the wheels off it, or buck up on some suspension.

Or maybe just have your's serviced, Blue... When was the last time that was done?

---

So it's not like something is WRONG or BROKEN.The bike is is perfect condition

You took what I was asking wrong, Blue... I was asking specifically about the suspension... I know you've got some miles on your bike... I figured that if your suspension is starting to act differently, it is probably due for service. Like every other part of the bike, the suspension needs to be maintained.

Sounds like you did some adjustment to it today and are happy now, though... Go for a ride... that's what I'm gonna do.

---

Okay...all good now.Gave er some more love...she's happy.

You read that quickly young Skywalker.You are indeed right however...I've not had any suspension maintenance at all in 4 years.It truly IS due.Just been puttin off doing it cause the thought of having my guy take the frontend apart...and the rear shock and all...geez....concerns me...that's all.But you are right.And I promise to do that here this year...the sooner the better.Thanks Dogo.(just funnin ya know on that 'deleted' post there!!!)And HUB...ya...thanks for your 'unput,er...I mean...INPUT'(ya Kooky prick) .

Today after adjusting,I purposely hit some nice sweepers and curves.My findings....when I really concentrate on hanging off....getting to the side of the bike,it tracks extremely well.NO hint of wiggle or anything.Speeds were above average.When I remain pretty much in the saddle...and repeat the same deals,at times,there is a teensy hint of movement...but nothing like before.I firmed up everything...preloads,dampings.Compression Damping.The whole shebang.It's pretty close right now I'd say to being what I would like.Just need now to be able to get away and really put er through some paces.RAIN TODAY!!!!!Geez...vacation's....GONE.Last day today.And THIS

Yes I did I did yes you know you can't fool the question man. He's not answering that tire... I'll take it as a yes. Unless otherwise, I'm all ears and now it rides OK without any maintenance as one stated?

Changed my forks @ 7,500 or whatever that interval cut in half? It's ready for a new round. I'll do that with the front/rear change next round.

---

Well...pretty much I'm gonna go with yer earlier assessment.Suspension "upgrade".I think it was you who said that,right?I watched my ONE vid I was able to take today,sure enough,there was the weave thingy blastin around a nice wide fast curve.HOWEVER...it only started at 130 this time...not 120!Getting closer,eh my man?And I do think the service interval needs to be followed a tad more closely with my bike.Yup....4 years now...never had a fork oil change,or the rear shock either.That COULD BE all she really needs...ya think?

Since I didn't ride er like this when I first started rollin,I've really NO idea if the chassis deal was acting that way or not

I'm uploading a vid from today....at 6:24-30,this is what I'm talking about.

It's like pulling teeth. You are chasing all these settings and I'm asking you a simple question about that wobble. If it takes one day after the other, "The wobble has a variable."

The vicTUMectomy has a right hand up that rectal cavity looking for that YEEEEEEEEEE YES! My wobble variable might not be old oil. Today's automotive tranny; can get 100,000 out of one dump round. Say, it's not the oils in the sealed shock you have no choice about [changing the oil on] that rear one, right? And did it sweep you around no problem? Wobby'that for awhile.

Man Card UP! Place a Yes, I double bubble screw the wheel weights. Was that you, blue? No wheel weights I use? All of a sudden we have to find two yes IS!

IS it YES - No wheel weights? Go look at your rims... Any on?
YES = One old one new Tires are sitting here and I am hooking it over a ton with one new one used; SAY IT!

---

Okay...honestly...I want your honest opinion on this.If I can correct it with suspension settings...I want to.HOWEVER,if it's a front tire issue...then I can better accept that.Look at the road surface in those frames.The bike is NOT leaned over that far.But the surface has kind of a "cement" glaze to it.You can see it.Probably from repairing with tar and stuff.Do you think the front tire is slipping ever so slightly?The tread looks perfect.Plenty on there.With a nice round profile.As I said....I haven't been able to actually nail down WHAT kind of road surface(s)this behavior actually occurs on.It's so iffy.If I could somehow "document" when and at what speed it's happening,and at what kind of lean angle...I could probably pinpoint IF it's tires or what.It RARELY does this at legal speeds.If ever.I'm having a hard time "believing" as Privateer said..."she's reaching her limits".That curve speed right there was approx 130.Certainly this bike is nowhere near it's limit at that speed on a curve that simple is it?What do you think?

I have to say Hub...I don't think it's wheel weights...I never use weights.She's way smoother without em...honestly.These Pirellis are very well balanced.Straight line runs...smooth as glass all the way up.

I truly think that my body position has more to do with this deal than anything else.When I'm carving hard,and I get OVER the side as much as I can...the bike seems to really feel solid...course the lean angle is a bit less as well...which would make sense if it was a tire reaching it's limit.The steering just kinda tracks "perfectly".Even at triple digit speeds.It's so "come and go"...it's hard to actually catch it or duplicate it.I'll experiment some more with my positioning....that really seems to change the feel of the bike when cornering.The tires look fine.

I've noticed with my bike at least,the position of my arms and torso,and how I'm contacting the bars make a lot of difference in the way she responds in a curve.The "push" method sitting upright is different than when I'm tucked in and over the side as much as I can,holding the tank with my other knee.It's kinda subtle,but I can feel a difference.Upright,the push is more downward.Tucked in,it's more forward.It does seem to change the way she feels while turning at speed.

Looks like it's still got a ways to go before it reaches it's "limit"...whattaya think?That unused portion gets smaller everytime I go out.If I hit that sidewall...what do you think will happen?The rear goes all the way to the sidewall,and "into" it just a smidgen....it still seems to be holding in the turns.

There was a guy on here I think...that had a pic of his front tire...it was all the way scrubbed in to the sidewall....I'm guessing it was a 14.I think so.

You are running sweepers not foot dragging or peg tagging. Tire looks hard. Say, is that a rise on the second groove down, left side [as you face picture]. Or say a shadow the camera made? Is it 'stepping?'

1. So, a nagatory on the weights.
2. Nag you till you come clean. If you are looking to hang it out;
a. Not the front end.
b. Not the rear shock.
c. Not the wheel weights.
d. Not another yes or no?
3. Yes or No. Are you running a used front and a new rear?
4. Yes or No. Are you running a used rear and a new front?
5. Yes or No. Do you change both tires as a set like a pair of socks
6. Yes or No?

---

#3...yes
#5...NO

I regularly get two fronts to one rear.As for the "stepping"...well I didn't notice anything odd looking.I rarely use my front brake leaned over.And on regular riding...I only gently apply front brake...these EBC's don't require much force to slow the bike....more sensitive than the stock pads and rotors...that's for sure.Next time I replace BOTH tires...I'll do some curve/wiggle tests just to see what it does.You could be very right about the front....being "hard"...I don't think it is TOO hard...but it's certainly been through more heat cycles and such,even if the tread appears "okay".My first Dunlops were like that...looked fine,but hard as a rock after several thousand miles.

Sweepers and such only,haven't had er leaned over enough yet to scrape a peg,though I have nailed my boottip a few times.(and not with it hanging below the peg either).So I guess I was pretty close to gettin the peg.

I'm not sure what you mean by "a rise"...on the second groove down...that looks okay to me...in both pics.Now,that 3rd groove down,on the trailing edge of the groove,upper photo,that one looks like it curled just a bit from being thinner maybe?But I can't think of what might cause that other than a slipping tire?Or braking...which as I said...I can't even remember the last time I used front brakes in a curve.Not on this tire.Tire pressures are 41 PSI cold.

* Last updated by: blue07 on 6/13/2011 @ 12:55 AM *

Okay...after reading up on the dynamics of everything,I decided to try a new thing...which I hadn't really considered before....something simple.I lowered my tire pressures from 41 cold,to 33-34 cold.

I went out and ran the big sweeper that I was getting a wiggle on before.The wiggle is gone,and my corner speed was increased.I had increased my rear shock preload last night.That probably helped some as well.The bike now is extremely smooth and stable while apexing through the curves...at least the ones close by(which will allow higher speeds).I came home,checked my tire pressure again....almost "by the book" heating.A raise of approx 3 PSI per tire.So the current pressures are in line with the tire performance numbers.

Tomorrow...God allowing...I'll be out to "recheck" everything...a nice good ride hopefully.175 lbs,2 lines showing up front.This seemed to work very well at not allowing the frontend to pogo or dive.I think she's VERY close now to being set just right for me.

The ride quality I thought would be compromised,cause it is pretty stiff feeling in the garage,just pushing down on her and rebounding back.But it wasn't.It was actually VERY smooth and comfortable.Better even moreso at speed.These settings are quite a bit more "extreme" than I've ever had them.They seem to be almost perfect though for how I'm riding.Just need now(maybe)to do some minor tweaking on the rebound damping,compression damping.The chassis feels WAY better on the straights and the curves now.

* Last updated by: blue07 on 6/15/2011 @ 12:52 PM *

A gentle high speed weave is usually the rear suspension is too soft. It allows the chassis to oscillate through the corner. As you found out, firming things up helps. An aftermarket shock works even better.

Mad

Is an aftermarket shock really necessary if your under 190lbs with gear

Been a long time since I weighed 190lbs... but I say custom suspension is in the same catagory as those BST's of your's, darrlye... Necessary? No... Will you be happy if you do it? Absolutely!
