Just picked up my 2002 M2 from a two-week "vacation" at the dealers... they were fixing a leaking shift shaft (for the fourth time).
Anyway, dude brings the bike around, choke out, bike off. I turn the bike on, ride off the lot, turn onto the main drag and the bike totally cuts power, like I can feel the power almost draining away. Just as it's about to "shut off" (so it feels) the bike backfires louder than it ever has before—sounds like a gunshot. Revs pick right back up and the bike seems ok after that.
Any ideas? Anything I should be worried about? Bike is stock except for the pro intake and carb rejet. |

Was the enricher still out? Sounds like maybe a jetting problem. Also air leaks such as intake gasket or exhaust leaks.

Yeah, the enricher was still out... I just installed the intake (not too smoothly either) and I'm wondering if there is a leak there. It seems to run fine otherwise.
An intake gasket leak would really be bad as I don't know how to "correct" that. I had a lot of trouble getting the intake on, of course, I am inexperienced. |

Search the board for methods of how to checking for leaks, it's not real hard. Great thing about the bikes is how simple some things are designed. Do a good visual, if new gaskets are need try again. I use a lite spray of silicon on the intake surfaces to prevent the seal from grabbing. Take your time, evaluate at every step and you will be successful. |

An easy way to check for intake leaks is to spray carb spray around the gaskets and see if the RPM,s change. |
