Dave, to be honest, I cant remember.
the motor was rebuilt by me last year, then it got fitted into the frame and youngest son had it all back to rebuild. Its been at his until he gave up on it after doing some wiring, he has been on shift 4 on 4 off, with two young kids and I work nights as well as working on my days off at the unit rebuilding and servicing bikes, I would have thought it was ok but cant remember.
will have a look at valves tomorrow asinlet cant remove cover as carb is in the way so have to make angle flange up which will cure the alignment to the air box mismatch..
