i had motor work done to my R and now i am jetting it for riding mx this spring and summer. from idle to 3/4 throttle is good. my main jet is not set right, i have gone through all the main jets i have (210-178) and it will not run right. the problem is when you get over 3/4 throttle it revs out right away so i am not getting to use the whole gear...what could be the problem? or do i just need to go higher on the main jet???
