Hello guys, Im Shawn and I just got an 86" a few months ago for the track for when I moved to Florida. Someone else built it, it was never ridden just broken in and he thought the tuning was "close", so I wanted to try to get it best as possible before hitting the track. Been here for 5 weeks and got my R on a dyno finally. Been a long time since I had a 2 stroke and I was never very good at tuning. Its a 330 esr, trx-5b pipe, ?carb?. I ended up getting it real close but there was so many people around and I was getting rushed because others wanted the dyno (was at a bike shop special event) I wasnt thinking clearly so I didnt get it perfect. I have 170 main, needle 4th clip down, 50 pilot. It was lean at idle (which I believe turning the air screw in should solve?) but he was bringing it to 4000 rpm then hit it full and it would lean out from there until 6000 then level off. Do you think its just getting to much air and the air screw again will solve this? Also it would just be a little rich all the way up 9500, but I was kinda happy about that, if I take air away will that lean it out up top also?
Thanks guys, sorry if you need me to explain it better, just say.
