Sounds more wire/ground/jobber related than a tuning [fuel] delivery problem. It is an 'input' is the frequency problem. This being a compuber bike, you need to know the reverse engineering to the computer. Or you be combuttear, crying how much left the wallet ass you reach around for it = See how I [keep working], but I vibrate and/or receive more voltage to my jobber and/or ground fault, being like it sounds like the components seem to keep starting up... To a point of (((Vibe))) @ 3,500 rpm.
1. What is the battery output past 2,000 rpm?
2. Are my battery posts tight at my battery's (+)&(-) posts?
3. And since I'm here feeling this out, what is my static voltage at the battery, being it sat now for awhile and how much are we looking at?
4. 12.8v is ideal. 12.6v is within range. 12.4v is not looking up to snuff. 12.0v is can't hold the 10th's of volts needed for sensor type jobbers needing a strong 5v. 11v all static is how you question the charging system?
5. Start and let the bike idle. 14.1/14.2 @ idle lets the bike be fed more than 13v @ idle. Then, blip the throttle to see if 14v is sustained with 10ths following.
a. It clears the charging system for shutter.
b. It clears the battery static if 12.4+v are showing a battery that can still hold over 12v.
c. It clears having a good ground from engine rotor/stator output to frame ground to battery ground and from pulling 14v+ to the 12v system.
d. It may, kind of, sort of, taking the guess = Jobber output signal's 5v ground in question, and/or jobber's frequency range out of spec.
6. Followed buy using a timing light taped to the handlebars.
a. Does my light shut off @ 3,500 rpm?
b. Does the spark keep a steady spark?
c. When the spark does die, is it at the same moment it hits 3,500 rpm?
