I KNOW I CAN GET TO 200 BUT RAN OUT OF ROAD(OK SAFE ROAD),

17F/43R should get you to 199mph. 17F/42R should be around 203. With stock gearing I have made numerous attempts. My bike will NOT do 200mph . Or should I say with me on it.

la busa es 18/43 stock. that would be about the same as 17/41 though wouldn't it.

I tied down the lever to the bar, removed slave and just put it aside (still attached to all lines. Did not remove any banjo, or lines.) The piston was up inside.

Did all the other stuff, and sfter I was done, LAST thing I did was release lever.

Yes, I have the service manual.

On page 6-8,
I followed the "Perform the following if the clutch slave cylinder is to be removed but not disassembled."

I then later when it wasn't working, 0n page 6-9 it says to remove the band from lever before tightening the bolts then cinch 'em down. That didn't work.

I figure Sat morning I'll redo the second para on 6-8, redo the bleed, and see what (if anything) happens to me then.

UnBooo-levable!!! This "little" project has morphed into some kind of evil mojo thing.
This weekend is our Street-Wheelers hot-rod cruise, and show and shine.
Me? I'm in a shed sharpening sticks to poke in me eyes.

I'll check in the morn before I go increase my blood-pressure if you've responded.
Thanks BTW for the tips and such.

My neighbor said I should get a Honda....I'm gonna miss him....

When you pull a clutch slave off.....if you don't use something like a c-clamp (what I use) to hold the piston in, its going to slowly creep out on you as it sits. That can let air in the lines, or it can cause the piston to stick out too far, and compress the clutch rod, which will be the same as you holding the clutch lever in all the time. Always keep the slave piston held in when off the bike....and always push it in enough so that its not contacting the rod when installed, you need to be able to pump the lever several times before the clutch begins to resist. That ensures that you're not preloading the clutch rod too much. Same thing you do with brakes to avoid unnecessary brake drag. Hydraulic systems are self adjusting, but they're like a cam chain tensioner, one way only. You always want to be able to pump the lever to seat them. If you let the pistons creep out, then stick them on without pushing the pistons back in for clearance...you'll have brake drag/clutch slip every time And that brake drag/clutch slip can easily lead to warped rotors and cooked clutches, and sometimes the rider will never know why These bikes are tricky little bastards lol. My friend, who loves to grab/squeeze/twist everything on my bikes when he comes over, decided to give my clutch lever a good squeeze when I had just taken my slave off, to change my front sprocket on my busa, and before I got my c-clamp on it. He pushed my slave piston out of the cylinder, and dumped clutch fluid everywhere. I coulda rang his fidgetey little neck I had to bleed the entire system. The last thing you want to do is squeeze the lever with the slave off

i`m running stock set up with 17/41! the zx12 was running 45 in the rear not sure about the front.but he was taking off and that front end was doing the dance up and down!! looked pretty dangerous if you ask me. i`m 6`4 280 so i know i need more power. but that Brock`s CT dual full exhaust is pricey! to say the least. i like the dual look of the exhaust, not really feeling the 4 into 1.....i was thinking of going up one tooth in the rear and see how that works. hope it doesn`t mess with the top end to much

Go 2 up in the rear if you can......1 won't do too much. 2 will def give you more acceleration down low, but like romans mentioned you still have the ability to do mid/upper 190's if you have the power to pull it. That would be a good compromise between more acceleration while still keeping a healthy top-end

17F/43R should get you to 199mph. 17F/42R should be around 203. With stock gearing I have made numerous attempts. My bike will NOT do 200mph . Or should I say with me on it.

A seriously doubt that a zx14 with 17/42 will have enough power on motor to push over 200 mph...
maybe +1 in the front will give you that top end.

gearingcommander.com doesn't factor all that in IMHO

Just for my own understanding here-the manual instructions of "banding the clutch lever" before removing the slave are incorrect?

i`m 6`4 280

Ninjaryder, your like me. We have our own natural air brake built in. More power is a must. I too have a wall of sprockets and I can tell for sure that last 8mph for me was climbing like Mounteverest... Me no can do. Please post your findings. Locating your bikes peek hp&torque and gearing for it will be a must. If you still have your Dyno sheets take a look to see what RPM your bike was pulling the hardest. I would love to see you do this. That 200 is a big # and I wanted to say it was possible, but for me the answer was No. How many feet above sea level are you ? Is your bike lowered ? Setting your speedo healer with GPS will also be important. I thought for 17F/41R was -7%.... You may have been going faster? Good luck and please be careful. Pints on me, hope to hear the Great News. Cheers

Maybe with 150lb rider. Slow did you make it to the holy grail ?

I went down to Vortex 16t in the front, which made a big different down low and I noticed my speedo was only off approx 5-7 mph with a gps. Now i'm considering changing the rear sprocket to the Vortex CAT5 black 42t. If I decided to go to a 42t in the rear, how bad will it effect my speedo? Will I definetly need a healer and how much top end will I loose?

16Front 42Rear with your bike at 11,000 RPM will still put you at 191 mph. Go for it. You can always go back. Lots of fun.

Thanks Romans. What about my speedo will it improve or get worst???

I've not been able to hit 190 as of yet with my 16/42.I'll be trying again soon.

You're going to top out at around 180 mph with the 16/42
and stock height rear tire.

There were a few guys that had their speed verified by GPS-
the best that a stock motored zx14 could pull with 16/43 and
a 190/ 50 rear tire was around 176-177 mph.

I don't have gps on my bike but with 16/ 43 and a 190/55 rear had
lower top speed in 6th vs a stock geared 09 R1 that was also in
6th and against the limiter.

Most of the top speed calculations on gearingcommander.com are just too generous IMHO.

Ya-that sounds about right-I was over 185-but not by much.When I went to check the top speed function on my speedohealer to get a pic of it,the speedo swept up to the top speed for that run,but went right back down-usually she holds for about two seconds.I think my bike had some more left,but I ran out of road.I do think if I had some aftermarket pipes on there that would open er up a bit more,I could probably hit 190 fairly easily.It wasn't that far away this last run.I'm fairly certain if I was running stock gearing-I'd be right around the 195 mark.She's GPS'd,and radared so I know the speedo is accurate.

With each gear change your percentage will change for the worse(or better,depending on how you look at it)As your percentage of gear ratio changes so does your speedos indicated speed. With out the healer your speedo will indicate a higher speed number # . Play with gearing commander is a great tool for this. I do run with a GPS and like mass reports, it is not exact but still helps. If you can run it to redline and find yourself doing this and want more it is easy to readjust. Still lots of Fun.

A top-end power oriented exhaust system (Brock's, Ti-Force etc.)
will gain around 15 rwhp at max rpm and the added power would be
enough to push over the 186 mph limiter in 6th gear.
Not by much but in the 190-191 mph realm.
Dubious had noticed that and posted his findings but it was some
time back- long before he started his turbo project.

Hey guys, Thanks for all the replys. Do you think the 16/42 is the best combo for street riding if I'm just looking for a little more punch? Dropping down 1t from 17t to 16t in the front was very noticeable. Will I also notice a big difference with going up from the 16t/41t combo to 16/42t combo? I still have the stock rear tire, so it sounds like she should max out between 180 and 190. I'm cool with that, I mean how offen will I be hitting those speeds in NJ with all the State troops around here.

16t/41t combo to 16/42t combo?

I'm sure you will love them both. My 2 cents = Skip it and go 16/43 or 17/45. I base this on money spent on sprockets. I was new and did not know what to expect, so I was changing one tooth at a time. If I had to do it all over again I would go straight to beloved 16/43 or 17/45 which I run now. At the time I was thinking lots of drama but was let down because with one tooth change at a time I could barely tell the diff. Either way, play with it and have fun. If your hitting the RED with those combos on a regular bases then it will be time for other measures. You might want to order a new tire now.

The 14's speedo gets more inaccurate as speeds go up...so even if its right on at 80, its still going to read high at 180. I've checked it with a gps. The only way to have it read right on at top speeds is to do the those speeds with a gps, then correct the speedo with a speedohealer for those speeds. But then it will be reading too low at normal speeds. The easiest way is to just use a gps with a top speed recall for your top speed runs, and forget about the speedo all together for top speed readings. Besides, to get over 186 you have to use a speedohealer that makes the speedo read low anyway, to bypass the top gear 186mph restriction. The speedometer really is useless for top speed runs on the 14, kawasaki made sure of that in several ways lol.

I've slowly come to the realization that going 1 tooth down on the front sprocket is always a big trade off-
my 14 with the oem 16T front (with the rubber- just like the stock 17T) does whine consistently under
accelaration. It's nowhere near the horror of the smaller Vortex front but it's still noticeble even with
my very loud exhaust. It does wind up through the gears quicker but the busy/ noisy feel about it does
take away a lot from the smooth bike that the zx14 is with stock gearing.

I rode my gsxr 750 for a first time today with a -1 in the front and I'll probably have to put the
stock front sprocket back in and get a +4 rear and a longer chain. As bad as the bike needs to be geared
down, for street riding the smaller front sprocket is just way too noisy and the bike picked up some
really unpleasant vibration.

At this point I'm strongly considering putting the 17T front back in and going 17/44 or 17/55 on the zx14.
I'll have to install a longer chain and bump up my collection of Vortex BST rear sprockets with two more.
Can't wait to mess with that front sprocket nut again too...

Decisions... decisions

Don't forget your clutch lever(LOL!!!!!!!!!!!!!!!!!)

The big bikes do feel the smoothest and most effortless with the stock gearing...less revs, less vibes. And aftermarket exhausts also give more vibes along with more power. With my busa and 14 they were def the smoothest stock. But at 5000ft up the busa was unacceptably lackluster in the acceleration department for my power junkie tastes. It HAD to be modded or else go away, no other options there. And the 14 was meant to be turbo'd lol. So I gave my stock smoothness away for very good reasons (imo lol), but gave it away I did

At this point I'm strongly considering putting the 17T front back in and going 17/44 or 17/55 on the zx14.

Mass,Both my zx-14 riding buddies are now running 16/43. With each install, a first to second gear and then into N run was made. With the bike shut off, I let them coast to a stop (I thought something was wrong). Nothing has been as smooth as the stock OEM 17Front sprocket. There is no doubt, 16F is Noisy. I am thinking that 17/55 above is a type -O Right ?

I don't get any noise from my 16T front-it's that Zephyr sprocket.(if that makes a difference?)I MAY go back to a 43 rear though-nice change.Felt like the bike actually was "tighter" if I could describe it like that.Shifting was sharper and more solid feeling.Only thing I didn't like was the running out of r's so quickly.We've a lot of semi-straights around here to get to the twisty stuff.But once in there,the combo works really well.At 80 mph,in sixth,you just feel like you want to accelerate out and shift again-but there is no "again".
