I had it bored to .40 and got a y67mm wiseco piston, and had the cylinder port and polished. Got a 300 main jet. Got a CPI dragpipe. Still a couple things to do on it. Thinking about changing carb for a 32mm oko.Plenty of companies make them in oof configuration. Question is if you have a stock blaster pipe now then you do not want a drag pipe until you do some engine work and mods. An oof pipe is built for the drags and porting,engine mods to suit. Shearer will run you $500 just for a bare pipe. RDZ makes some but good luck getting one after you pay. If you are talking an in frame pipe then your choices are limited to what one would consider a drag pipe. Let us know your "goal" with this bike and we can help better.

oko are horrible carbs. Stick to keihin or mikuni. I prefer Keihin. oko's are junk chinese made knock off's and I have seen plenty of issues with them. I still think you will need more power in order to fully use that pipes capabilities.

I got a mikuni carburetor. I got a question i put a 300 main jet and after 3rd gear if i go full throttle it dies sometimes. Sometimes it will go full power but sometimes will die at top speed.
