Re: cough spit fart studder under 3k rpm
Correct me if I am wrong in any of this. Copied from a previous post:
Under 3K is pretty low for a high compression, short stroke engine. 4K+ is really where it runs better.
Everyone is going to say sync the throttlebodies and set the throttle position sensor first.
As I read, ~4K is where the secondary injectors kick in, and the transition is not very smooth. From the factory, the bike runs lean throughout the RPM range, more so in low RPMs.
Add a TRE. Each gear has it's own map. One unique thing about a TRE is that it will "fool" the bike into thinking it is in another gear. Depending on the resistor value, it will run either 4th, 5th, or 6th gear maps for all gears. Maps get richer as you go up, but are all too lean for optimum performance.
After 1 year of messing with my TL, I think I finally got it as smooth as it ever will be. Each successive mod helped a little; there hasn't been one cure-all. Yosh box helped the most, but each was important.
My personal reccomendations, in order:
TRE - helps some
Sync TB's and set TPS - frequently go out of adjustment
41 or 42t rear sprocket - bike will not be as sensitive to throttle changes, particularly in 1st gear
Remove PAIR - get rid of backfires and allows tuning
Airbox mod - less turbulence in airbox, smoother airflow
Aftermarket air filter - better throttle response
Aftermarket exhaust cans - it's just a matter of time before you do
Lower temp fan switch - lean bikes run hot
Yosh-box or Power Commander - after most common mods are done, this is the icing on the cakeLast edited by Suprachrgd82; 08-26-2010, 11:52 AM.You do not talk about Fight Club.... -

Re: cough spit fart studder under 3k rpm
Dirty injector, dirty fuel filter, or vac line problem (broken, cracked, unplugged, etc.)
Easy diagnostics first, then tear into it.
Use a propane torch, not lit. Discharge gas while the engine is running near the vac lines. Engine speed will increase when you are close to an open line.
Have you been using fuel with a high ethanol content? Ethanol is known to break down rubber hoses. Fragments of the hoses will deposit in the injectors or filter.You do not talk about Fight Club....Comment

Set the TPS, balance the throttle bodies, recheck the TPS. While you're in there look for vacuum leaks. Make sure the TBs are properly seated in their inlet boots."The rifle itself has no moral stature, since it has no will of its own. Naturally, it may be used by evil men for evil purposes, but there are more good men than evil, and while the latter cannot be persuaded to the path of righteousness by propaganda, they can certainly be corrected by good men with rifles."

Re: cough spit fart studder under 3k rpm
Hi have a look at the wiring under the r/h side panel you will find the plug with 2 wires its the crank shaft position sensor if its loose it could be the source of your problem also look for corrosion in all the plugs ?
Hope it helps .
