Was the bike oil injected before the rebuild?
Have you actually ridden the bike since the rebuild?

My initial thoughts, I'm with mtec666. Only because I had the same issue last time I started up my MC21.
Have a good crank, so I will replace but you could have the same issue. Right chamber more smoke that the left.

Here's a vid - may help.

All Rothmans now.
