366 is In

List if you're looking to do a cheap (although a pain in the ass to install) mod this is the one. Throttle response is much better, smoke is better, and torque comes on instantly. Best mod yet. And the fact that my speed and power doesn't start petering out at 75 is also good. Got it up to 85 for the first time yesterday and I backed out.

Very worthwhile mod to do... while you're in there , I also advise you change out the throttle shaft O-Ring. Top of 4th in mine now is like 93 MPH !!! Still have 5th to go !!

When I went in the pump the first time and put it back together that o-ring started leaking. So when I took it down Saturday a new o-ring was installed as well.
