Calling all you HEAVY hitters!!!
i can not for the life of me diagnose what the problem is with this CB360 (cafe, pods,re-jetted keihin carbs, 2-1 MAC exhaust), . I have gone over everything that i can think of, two or three times to no avail. i have done so much to this bike that i am not going to list it all here, but hope that one of you more seasoned vets will be able to point me toward a simple mistake i have made or something i may have overlooked.
The symptom is this:
Bike starts great and idles perfectly. It rides great, pulls hard and has power to spare. After 10-15 minutes of hard riding it develops the slightest hesitation (correct term?) so slight in fact, i can not tell if it even exists or if it may just be bumps in the pavement, but it feels like there is the tiniest little buck, or jerk...but then again i cant be sure. The BIG problem happens at the next stop. I get a hanging idle that wont come down, it hovers around 2500-3000 RPMs and stays there for a minute or so before finally settling down to about 1100 RPMs before it wants to dip even more and finally die. It also begins to backfire thru the exhaust and develops this "ploppy" miss-firing (correct term?) "pup-pup-pup-POP-plop-SPLAT-pup-pup-pup" etc... type of idle...you can just tell something is ever so slightly amiss...AND I CANT FIGURE IT OUT!!!!! I'm going to ride it home after work like a rented mule and sync the carbs AGAIN (while hot and having these symptoms) and go thru the points timing AGAIN (while hot and having these symptoms)...i'm counting on you guys!
PLEASE HELP!!!
