Hi there fellas, I've stumbled onto you great forum while looking for info on resleeving a Yamaha IT250K bike. I'm a senior dirt rider having passed 60 but still regularly ride vintage dirt and modern (KTM 2 stroke) and road FZ8 Yam. I've just replaced the gearbox in the IT having lost 3rd gear earlier this year at a vintage weekend(circlip on the main gearbox shaft came out of its groove and caused some damage). Now my issue is the IT is on its last bore and it is really going well which means when I take it out it gets ed and if it blows I have a problem.......no more bores left. I think somewhere I read the Yam Tri-Z 250 has the same cylinder as the 250K. Anybody have any knowledge of that. Anyone know where I can get a new sleeve other than LA sleeve. Anybody know of parts bike where I might get a good donor barrel.
Thanks for any help...Cheers Bill
