TM 250 oversize piston.

[Rider]

My TM 250 barrel is out to 2mm oversize but needs a rebore. Has anyone found a piston that is compatable. I have used the largest size (72mm) that Wiseco supply.  Regards Terry.

I have found out that Wossner has a piston that will fit, but the skirt length must be reduced by a couple of mm's. The guys at Serco should know this and they have a technical note on what needs to be done. You can phone and check with Serco Wooloongabba Brisbane. I hope this helps.
