also would i what jets do i have to replace and about how many turns out on the air fuel?

i believe there are only 2 jets available, stock and a 90.

we have been running stock jetting with a full big gun system (oversize) with a stock bore 11-1 piston for nearly 2 years.

thanks

it surprised me also. but we do run a lid with uni filters. we have run without a lid in the right conditions with no ill effects.

we bought a second 90 with the t4 slip on and it was jetted with the #90 jet. we didnt notice any difference between the 2 quads when riden.

with the stock carb we run a 85 jet all sizes are available.what works better is a carb from a xr-80 motor cycle.it comes with a 98 jet which should be close.i have a new xr-80 carb for sale if your interested.e-mail me.globalcandle@peoplepc.com
