Hi all
Fisrt of all apologies for crashing your forum.. I'm currently working on a Yam XJ550 and seeking to put a xj600 engine in it. The engine I have though would benefit from a rebore and that's where I hope you can help..
The bore of the XJ600 is 58.5mm same as the CB550 I understand. Problem with the XJ though is a complete lack of o/s pistons. I'm looking for a 59mm or thereabouts - the XJ uses a 15mm pin and from top of the gudgeon pin hole to the deck is 17mm and to the crown is 25mm close as dammit. Do Honda suppliers have anything close ? Even a new set of standard rings for the Yam is going to be about 150 quid.
Anyhow hope you guys might (through gritted teeth) have something to offer a beleagued Jap owner,
Cheers
James
