Some XBR stuff is getting harder to source these days. I think the gudgeon pin is no longer available from Honda. I wonder could an engineering company replicate a pin for you. Predator UK do a conrod kit but without the pin and if you have look on ebay under "Honda XBR 500 - Rod Kit Prox - 401602" they have a couple for sale in France.

Also the company below offer a complete piston kit. Either way its going to end up quite expensive and sourcing another engine may be the option - but unless you can hear it running that's always a risk.

Any recommendations for someone pressing apart crank for the conrod, & also gonna rebore & replace piston due to wear from the piston rocking side to side due to worn small end.
