Hi John
Thanks very much this is valuable information for me, yesterday I made contact with a person I was directed to from a custom motor cycle shop and he has said many things to me that are consistent with what I have been told here. He mentioned the valve seats are cast into the head and should not be replaced if at all possible and he did say the guides can be very tricky if not dealt with very carefully. he went on to describe correct cam follower fitting etc and explained the risks of letting a modern machinist at the head and barrel.
I have some comfort in talking to him and he was not that keen to take on the job until we got talking about the bike, I think that speaks volumes sometimes!
This guy told me has has owned a few Dominators and they were among his favorite bikes, he is not able to look at my stuff for a couple of weeks but he does live not too far away so I intend to wait until I can see him and assess his background for my self.
It does sound like he is retiring from doing bikes or at least slowing down his work load so here's hoping he is well experienced!
Can you tell me what size the nuts are on the crank shaft flanges? I don't have any whit-worth spanners any longer, I am ashamed to say I discarded a significant amount of them years ago!
I went to undo the bolts last night and discovered nothing imperial or metric will come close!
Cheers
Kiwi
