| Looks to me like Craig has had a valve seat crack (suprised considering the results of the compression test, Probably why I prefer leak down testing) which may have something to do with the cam belt jumping a tooth in the first place.
Craig had swapped the front cylider head with one on loan from Bradders which was his first time at trying such a job, Kev P (Senna3) sorted out making it oil tight and torqued it down properly as Craig didn't have the right tools.
I refitted the Belt and set the cam timing to the factory marks and got the bike up and running, with the Pick-ups and head replaced the front pipe was certainly getting hotter but things still weren't quite right
So after resetting the pilot mixture screw I then balanced the carbs.
We also junked the non working vac operated fuel tap and fitted an inline CPC connector with a inbuilt shut off valve
All seemed to be pretty good when it came off Kev's bike ramp.
Having the valve timing set up properly wouldn't hurt but at least its sounding like a twin again.
Just needs Craig to take it somewhere to test it
