Default Re: what did you do to your motor bike today?

Road up and down the block to chex the tune all's well-I would like to try a #77 or #78 jet I'm running with a #76 4th clip slot down on the metering rod - I have no drills smaller then a #76 it's fine the-problem is the exhaust-I'm scavenging fine but port blocking and any" back flow " can't remember what that's called, is not good after 7/8 throttle 35mph+ up slight hill a little better down that street
maybe if I crimp down the 3-3/4 out side circumference head pipe just before the muffler body it would help with some back pressure the stinger is tuned good I think the head pipe is the problem at top end
