Original, on left. Disassembled backward if you remember. On right, the third and newest acquisition, beginning to split cases. Oil strainer is literally packed with metal to the case floor.
Wiseco is the only manufacturer that I found who still has pistons for the 87 TRX250X - piston # 4440MI assume wiseco is still a premium piston? Was back in the good OIL days...
Are there interference issues with the 12:1 wiseco in the 250x, camshaft? I am not seeing head shims available. Or what is the remedy if issues occur?
They also gave me a name for possible cylinder boring locally. I will try to check tomorrow.
