Yep, the yanks always know best  ??? Even though i have hundreds of questions from them each week  :o

Paulreade:
Yep concensus seems to be 1/16 th drill bit. Have just ' bench synced' the slides and chokes as no 4 was slightly out of kilter.
I like to post on both sites as it's interesting getting feedback from owners, whatever the background. I think the secret is to consider fully the responses and act accordingly. Having never 'tinkered ' or 'fettled ' a bike since the 70's it's an interesting learning curve for a 'diy' mechanic. So far though I haven't broken anything and the bike is showing gradual improvement.

By the way graham, took the engine to Des and he managed to retap the threads without a time sert so fingers crossed for a rebuild ( partially there) and assuming I manage to get it back together the same way it came apart it hopefully will fire up. If not I suspect I may have to post again with list of Q's !!!!!

Trigger:
That saved you a long trip to the other side of the country  ::)

Paulreade:
Agreed, stuck a powerful suction Hoover to the exhaust stub with inlet valve closed and exhaust open, left this running for a few minutes and didn't get anything out apart from a few black bits ( very small). So hopefully all clear. If it fires up I'll fire up on 1/3/4 and leave plug out of 2 for a few revolutions. Fingers crossed !!

Trigger:
If any small bits left on top of the piston ( very unlikely ) Start the bike up with all 4 plugs in but,not the exhaust of the cylinder that has been re tapped. You need pressure from that cylinder to throw anything out with a quick blip of the throttle.
