160/165 and third notch on the needle. The problem is i rev it real high when its in nuetral, i mean high, and it starts pouring out black smoke, but when I reving it the same in first it doesnt seem to do this. Thats my problem. I mean i rev it to the point were the frames twisted and touching the ground but i dotn hold it there kind scares me.

 

Oh now I understand...

This is an easy fix


Don't free rev it in nuetral that high....next please

 

I see we both got the same pipe, what set up are you running w/ ur jetting? No lid or lid?

 

155 160(not dynojet)
needle at the 4th notch
a/f screws 2 1/2 and 3 turns out
no lid
These settings are at 1000feet on a 85degree day
my quad NEVER ran good until I cut the crap out of the top
