Cervantes Posted February 16, 2006 Share Posted February 16, 2006 I'm doing a complete rebuild of an old xs250 (81) i got most things done and finally got hold of a complete gasket set but i can't find anywhere that sell piston rings so my question is is it possible to refit the original rings and will they be ok?

Evilbay has loads. You are best to at least get the bores honed (45' crosshatch)and new rings, but you need to measure the bores first(i'd get your local machine shop to do that accuratley) to determine any wear. try www.Motoward.co.uk give them a call on 01403 824222 they have computerised OEM stock and are really helpful, and suprisingly cheaper than evilbay on some items motolink @ www.yamahaspares.uk.com if you are looking for any 2nd hand spares i have a 250 engine partially stripped in my shed Link to comment Share on other sites More sharing options...
