If it's not a stock carb you need to figure what carb it is. And like blaaster said get yourself a b8es ,actually grab a few so you can plug chop once you get it running.

Are you using fresh gas? Old gas can give you all kinds of problems. I just recently ran into a similar problem with a sled of mine, check and make sure there are no nests of sorts in both your intake and exhaust.

We all know it can be frustrating at times but stick with it and we will get you going. Did the bike run fine before the bore? What was the reason for the new bore and piston?
