What did you do on your rebuild service? Did you replace the piston & rings? It sounds like a low compression issue.

they will also do that if you put the piston in backwards. the arrow on the top should be facing towards the exhaust bridge/front fender

I second the privateer on that,make sure the arrow is toward the front,when you rebuilt did you remember to knock a lil edge on the power vavle,if you bored the cyl, there is a possibility it can snag the rings and break them.

did you re-jet it after putting on the pipe?
