[QUOTE="Bill Thomas, post: 108091, member: 485"] Not sure what you mean Jez, Comet wheels are same thickness with a big hole the other end of the bigend hole, Twin wheels have a big bit milled away near the bigend. I have been told someone fitted Twin wheels to a Comet, But I think it would have Shook !!. I am about to weld a bit of the bigend hole and bore it a 1/4" nearer the edge of the wheels, To change the stroke from 90 mm to 102mm ish ?, I keep thinking of nicking another mm or so !!. But I think it will be a disaster, I work + or - an inch !. Just bought a spinning centre for my lathe, And am sure it don't run true, So what chance of trueing up my wheels !, I have a set of V blocks, So could use them. Don't want to go bigger piston, It would mess up the C/cases for anybody, After I have gone, + the cost and I don't like squish and T/P parts. We will see, Can you P.M. me the price of your Conways Crank, I could maybe pop it in later ??, First thing is to get it on the road, If I can get a number plate for it from Simon. Cheers Bill.
