Re: Low RPM Sputtering
my bike used to sputter a lot when i got it, real bad below 5krpm.
i had quite a bit of problems , and after getting the bike working really smooth to where u can coast around no problem in first gear at 4k rpm, no sputter
ill say you should check on all of these things, as they are pretty simple.
First run through your diagnostic mode, using the service manual (located at r6messagenet.com if u need it)and check each injector.
next, also in diag mode, play with d_01, which shows the value for your tps. just roll on and off the throttle with the bike off and look for smoothness in the numbers, especially when barely on the throttle. make sure it never jumps numbers or anything, but goes up or down smoothly depending on throttle position.
Ive always steered away from the Fuel injector cleaner things because ive had some friends with bad experiences on their cars, and i know on bikes we dont get checked for emission but still, i like the old school SeaFoam treatment. Ive used it in my car with great success using the brake booster line to inject the SeaFoam straight into my engine, and it completely smoothed out my rough idle on the R6. I just followed exact dosage on the back on the bottle after a fresh fill up at a gas station, did this for three gas tanks.
