jetting?

[Honda#4]

i just recently put all my discs on my wb bros pipe and my plug is black but not wet and it dont backfire so what would be my options i kind of want all my discs on tired of having bottom end.

how long did you run the plug before you checked it?

start the quad and let it warm up...

take out the plug and clean it with a brass wire brush real quick..

replace plug and drive quad around not at real high rpm about 2 minutes..

in second gear...hit wide open throttle but not the rev limiter and hit the kill switch..

take out plug and examine..

if you are still real black, put a smaller main jet in and retry

ok i'll try to do that tomorrow.

you should need a larger main jet, but if your plug is wet you may have other problems. does you bike smoke at all, have you noticed a decrease in power. if so i think your cylinder walls are scratched and your gunna need to rebuild it.

no my plug is not wet it does not smoke one drop and it performs really great i love the power i just want to keep the topend power .could i take the airbox lid off or will i really be running rich or will it lean it out.
