    i had a pm... same as EVERY new member seems to directly ask me silly things like this..

    1. theres a guide on jetting/rollers
    2. theres a million and one bikes about with a similar setup but just to keep things simple

    start at around 92 with the jet, it will be big. never used a pm 50 pipe so wouldent know on rollers.. would guess around 4.5 and work heavier till the revs drop off (read guide if you dont understand) should get you runbning atleast ;)

    its too much mix not too much fuel in the mix.. drop your roller weight. sounds like there holding it back. like i said bang the 92 in.. it will be rich but wont cause any harm and you should be able to set the transmission up with that jet.. once the revs are doing what theyt should lean the jetting out ;)
