Yep, thats about as far as i have got. Latest measurements by way of calipers and micrometer are 53.975mm and 53.86mm respectively, both about as rare as hens teeth......UNLESS.......somebody knows different of course (or has a secrect stash of unused pistons and rings!!!!!). Maybe of course I should just try the tyga 300cc conversion.....unless the crankshaft won't take it!!!!!!!!!! doh!
