Gday All,
Just added Yoshimura R-77 Titanium slip ons (not an easy challenge) and a K&N air filter to my 2007 ZX-14.
Do I need to get the ECU remapped for these additives or am I okay and all is still good?
I am concerned the bike will run lean with the changes and that's the last thing I want...
Thanks and Regards,

No remap or PC3/PCV is needed for slip-ons and K&N I have two brothers slip-ons and a K&N and I’m at 40,000 miles and she runs like a Swiss watch!!

Thanks for the response.
I'm not interested in changing any performance characteristics or chasing more HP. I don't drag or race but do quite a bit of "spirited" touring and the bike is plenty fast enough for me.
With the new slip ons and air filter I just wanted to make sure the bike wasn't leaned to an extent that the engine was at risk of damage over time.
The bike runs great with the changes and doesn't over heat so looks like all is good.
Thanks again...

Any time!!

Is this case across the board?
Considering installing M4s on my 2008.

It was suggested to me that the ONLY slip-on or full that can go on without remapping/ upgrades is Vince products. Otherwise modifying the fuel, air intake, etc.... is mandatory.

Any real insight is appreciated.

Well, if you think about it... The fueling system was designed for a specific flow of intake air and exhaust back pressure with a limited range/ability to adjust due to atmospheric changes. If you make a minor change like replacing the air filter the system should be able to handle the flow, if you make several minor or major changes the system was never designed to handle the changes.

If it was my motorcycle I would definitely use an after market ECU to load an appropriate fuel map as I'd rather not risk running the engine lean and burning out the valves or pisons (even if the motorcycle seems to be running fine).

Did someone that works for Vince products tell you this ?

Slips would be fine, if worried afterwards pay Dyno operator 75 dollars to give you a run with no mapping. Peace of mind has value.

I just don't undersyand people who will spend $$$ for slip-ons, $100 for an air filter that may not provide any benifit other that letting in more dirt than stock but not buy a used PCIIIusb on ebay then spend $50 for an email Jeffo map or $200 for a dyno tune?

My local bike shop gave the advice about the Vince/ non-Vince products.
No matter who you talk to it seems to be a debatable topic whether to remap for slip-ons or not.
I just want a better sound. The bike provides me with enough performance for my needs.

Yep, selling the products to help of course.$$$$$$$$$$$$$

No matter who you talk to it seems to be a debatable topic

You will B fine with out. 1000's of guys running full pipes with flies removed & no piggy.

Drag racers all ran the new 14R with new Brocks 2-1/4 Big header with Zero fuel changes. All were fine. Ask around, all good.

I just don't undersyand people who will spend $$$ for slip-ons

Huge weight saving has value ?

$100 for an air filter that may not provide any benifit other that letting in more dirt than stock

Wash and re use is sweet. Make more power when they R New, then we over oil them and then they make less power lol

but not buy a used PCIIIusb on ebay

Def way to go.

spend $50 for an email Jeffo map

Lots to say here as I have the jeffo Maps,,,,, shhhhhh. Guys here get mad lol.

$200 for a dyno tune?

Sweet deal if you can get a pro.

I ran the Muzzy full Pipe Map with my Muzzy slip-ons for 2 years. Best By far, All Good.

Nicolapalooza, You will B Fine not mappings slips. Maybe even slower once some clown builds you a shit map for 300 bucks and it runs like a diesel truck or burns your plugs off.

In the end it's all up to you. Let Black soot B your guide, only then will you know you got ripped off. cheers

If it was me I would never again map for slips. I've learned by study, it's not needed,,,

Thanks for the input.
I was a little uneasy after talking to the local shop about needing to remap for slips and that being the advantage of Vince cans (especially where he doesn't sell Vince products). Still on the fence. I guess time will tell.

gday again,
interested in the black soot comment.
for the dummies, ie me, could you elaborate on that one please?

Why do people here get mad about Jeffo maps?
I heard from fellow riders that he really knows his 14s.

I would expect that the black soot comment would be suggesting that the bike is running so rich that soot is forming on the tips of the exhaust. However, from most of the vehicles I have seen this is normal, while the fueling system is running in closed loop mode and running rich while waiting for the O2 senor to warm up there's a good chance you will get some soot.

The exhaust gases that far from the engine don't get hot enough to burn them off during regular riding so IMO this isn't a good indicator as to how the motorcycle is running during normal operation.

After I got mine tuned.The tuner said the Brocks map was very rich.He leaned it out abit and it still is sooty.But it runs great.

This was a big topic here. Some members were banned and some just left over it. Some had to get there bikes picked up as plugs were burn't off,,,, Subject turned nasty real quick,,,anyway. Link any one ?

Yep.

so IMO this isn't a good indicator as to how the motorcycle is running during normal operation.

But it is a indicator none the less.

Simple test, as I know most of us don't have data loggers or AFR gauges and doing plug chops is lots of work.

Ride with your buddy, keep him in your tail pipe. Go wide open throttle. If he can see the soote bellowing out the exhaust in the different parts of the RPM range and smell fuel,,,, well this is a indicator that you may be rich and where in your rpm scale.

Soote on pipe builds up how fast after you clean it ?

Your map plus #'s also a good place to look.

Dyno Jet put out a Muzzy M-10 map early on with plus #'s off the chart down low in the RPM.

Hope this helps guys, take it for what it's worth. Cheers.

"Soote on pipe builds up how fast after you clean it ?"...pretty fast....it's gonna happen....long as it's not 'caked' on there...just a fine coating...I wouldn't worry...at least you know you're not running lean;)...I mean...that's my opinion...opinion only.

pretty fast....it's gonna happen....long as it's not 'caked' on there...just a fine coating...I wouldn't worry...at least you know you're not running lean;)

Lean is not what anyone wants Grn but Rich is not good either. Each has it own set of issues. In most cases the rider has a good gut feeling about his or her personal toy. We are all a bit different on the fussy scale this is why giving advice over the net is not easy.

Like posted above, plug chop will help to ease your mind, if this subject is on your mind more than it should be. Cheers.
