Exhaust question
« on: August 29, 2011, 01:40:01 PM »
Would running straight pipes on an 81 cb650 make it run rich or lean?

Come on, you can't tell me none of you guys ever tried doing this.

Even an educated guess would be appreciated ;D

Not to claim to know anything from firsthand experience, but I would THINK it would run lean...

Less back pressure from exhaust means more air in, means lean fuel mixture.

I'm having this problem on mine right now, PO put a really free exhaust on it to make it sound "more like a harley", and now I've got to deal with it. I'm actually just gonna wait until I can acquire a new exhaust... anyone got a spare? ;)
