Curious if anyone has ever ran into this issue. My cbr will cut out randomly usually when cold...normally happens really bad first practice round and once in a while throughout the day. I can be full throttle down a straight and it will start bucking or exiting a turn. Besides that it runs perfectly not sure where to start with the diagnosis
Are you running a piggyback such as a PCV? If so, custom map, downloaded map, etc... any work that preceded the issue?
Check the kick stand start lock out switch.... If it wasn't cut from the harness it may be sitting there on the edge of being on/off and causing the ignition cut.
Try removing it 1st. Might be a bad plug or a bad unit. Or like venom wrote, the side stand switch. Also check all your grounds.
I had a weird problem with mine that was a bitch to figure out. This probably doesn't relate to you, but keep it in the back of your head if all else fails..... http://forums.13x.com/showthread.php?t=307926
Thanks fir info...worst case I'll try new ecu ...yea problems like these are kinda a shot in the dark...worse thing about my problem is I have to troubleshoot at the track since it's the only place I have the issue.
