A little smokey tho.
many of these engine tend to smooth up some after two or three tanks of gas run through them.

where did you get your engine?

The reason I ask is that there are some that are known to be better balanced than others, I have a couple that have horrible vibes because of a badly unbalanced crank, but I have others that are ncomforta ly balanced from low down all the way to max rpm.

Just be aware that even the well balanced ones will still have some vibes, a single cylinder 2 smoker cant be perfectly balanced to be smooth at all rpms, but some of the newer china girl engines are way better balan ed than swhat we got a couple years ago.

Did you rejet the carb?

a of them I have had co.e with a jet thats to big and that causes the engine to 4 stroke which also makes them run rougher.
I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
