Hi to All, I've had my K2F competition Maggie back in for a while after rebuild, and the right hand cylinder timing is miles advanced. The bearings were completely flogged out before rebuild, so could this have caused the points cam ring to wear unevenly?
The right hand cylinder pings when going up a hill, so I want to fix it before I put a hole through a piston.
I have not put the degree wheel on yet but I would say it's probably 20 degrees more advanced than the left cylinder, and it can't be tuned at idle, only runs on the left cylinder at idle.
I was reading about Sid Lawton and his preparations for the Thruxton 9 Hour and he said he always had to file the points cam ring when preparing a bike to get the cylinders to fire 180 degrees from each other! And this was on new stuff from the factory! Although he was probably talking a matter of 1 or 2 degrees.
Is this the only cure for this problem?
Thanks
