I got my CCT and my spark plugs changed a couple of weeks ago. I noticed quite a difference in performance with new plugs but I have a new problem. My idol surges withing a couple hundered RMP when I am at a stop sign or the bike is in neutral. Is this normal or do I have some type of other ignition problem?

 

are you running a pipe on it? You may need to get your throttlebodies synced. Also who knows maybe you have a vacuum line open.. i found the T fitting coming from throttle body to fuel pressure reg was broken and my idle was flucuating and I was having a lean miss at idle and just off idle. Well hope this helps. I know with pipes bikes seem to not be so smooth at idle. Well goodluck

 

yah dude I have a slip on yoshi. Maybe I will throw my stock pipe on and see if there is a difference. Is my aftermarket pipe hurting anything?

 

Does anyone else have any suggestions? The bike seems to run fine when in motion but when I start her up or am at idol, it fluctuates within a couple 100 rr's. This really worries me. Does anyone else have this problem with a bolt on yoshimura pipe?
