cheers kev will keep you in mind for build...but i might have a go at doing it myself. the only thing thats stopping me is the timing chain and how the piston + conrod comes out? i keeping thinking its like a car job head off, sump off, conron caps then push piston up though block!!! done many car engines but never bike i guess its the same but is smaller scale, think i will read the xt manual PDF file first before i open a carton of beer and get to work...
