I have an 06' yz 144 kit from Athena. I need to replace the piston and rings, but they have been back ordered since Oct, with no end in sight. Has anyone used a wiseco 58mm in the Athena Cylinder? I suppose I could buy one and measure it up but I am trying to avoid that. Any ideas??
The piston I would use would be Wiseco's 58mm Yz piston. The same piston one would use for an E.G. yz 144 kit. I will probably pull the cylinder off and compare pistons clearances etc.
