aztwin350 Posted July 7, 2013 Report Posted July 7, 2013 did a chop today. let me know what you think i need to do. trinity head 30mm carbs fmf gold series into turbine cores unis with no box v force2 reeds 330 mains 45 pilots air screw 1.5 out needle on 3rd groove. i dont know if its a stock needle it seems flat on the bottom. doesnt come to much of a point. should have got the number off of them to check or show a pic. 3400 ft elevation like always thanks for any advice Quote
trickedcarbine Posted July 7, 2013 Report Posted July 7, 2013 Looking pretty close man. What did your strap look like before you chopped it? Quote
aztwin350 Posted July 7, 2013 Author Report Posted July 7, 2013 Pretty clean with just a little black. I was wondering if the stock needles have a blunt in or have a point. I was thinking of replacing the needles for stock Quote
Starwriter Posted July 7, 2013 Report Posted July 7, 2013 Yuh thenk mebe 45 piluts mite indercate thut sumthins weyrd? Quote
RadarRacing Posted July 8, 2013 Report Posted July 8, 2013 That looks good by the pics. If you have crisp throttle response and it sounds good the needles may be fine regardless of what they are. I like to chop em at 1/2 throttle and like to see em richer than WOT. They are annoying to ride if rich at mid throttle but dont go quite as lean as WOT. A good brown ring a little wider is fine at half throttle. Quote

aztwin350 Posted July 8, 2013 Author Report Posted July 8, 2013 i think i got it jetted really close. ended up a 300 main 45 pilot needle at bottom 1 turn out. ran great through all gears might go to 310 just to safer on main. thanks for all the help. i wonder if the compression gauge is off it ran great started on first kick. if its supposed to have more it would be pretty fast. smokes my lt250 which has some upgrades pretty bad Quote
