with 330 you could feel it not pickup any speed when going from 3/4 to full throttle. when i pulled the choke out it would pick up a little. what do you run your oil mixture at? im thinking if i move the mix ratio to 36:1 or even 40:1 and the temp warms up to between 90 and 100 the jetting will probably be 320 or 330. my current mix ratio is 24:1

thanks. we figured if we had a fairly big leak the starting fluid would pick it up, but i will build one of those and test it to see.

yeah i have some pics but i dont know how to post them, you have an e-mail? this mornin we sprayed starting fluid on the base of cylinders, head, exhaust exits, top of carbs, intakes and reeds. it never picked up rpm until we sparyed a little on the air filters. i will keep a eye on everything and appreciate the suggestions

ill look into it, i threw away the boost bottle and got a stock crossover tube because i read they cause air leak problems.

i talked to the guy who owned it before the guy i bought it off and according to him the cylinders are drag ported. they guy i actually bought it from said they were trail ported so who knows. they are ported but i couldnt tell you the difference in a trail port or drag port. it has v force 3 reeds, nology coil and hot wires, 66mm wiseco prolites , prodesign timing plate set at 4 degrees (it was at 8), cool head with 18cc domes, sst pipes with power core 2 silncers and k&n clamp on filterson stock carbs and im around 900 ft elevatio jetting was done during 70 degree weather. my mixture is yamalube 2r mixed at 24:1 with rocket brand leaded 112.

long story short i bought a 03 shee, i was so excited as this was my first two stroke but a couple hours later the right piston melted. thanks to the huge amount of info on this site and a few parts from sponsors i rebuilt the topend and now it runs awesome. the previous tune was so far off i would have burnt up more pistons if i had just put it back together the way it was. it previously had 280 mains but now has a 350s and it leaves about 2mm brown ring on the plugs when i done the plug chop. so once again huge thanks to everyone on here.

orderd some domes form noss machine and a few things from f.a.s.t racing. my wife said both were very friendly/helpful on the phone. everything arrived right on time and was packaged well. nothing was dinged or missing, that says alot considering the ups man thinks that his truck is a rally car out here on the back roads. will order from both again when the need arises.
