Hey guys,

I have a 92 750 VMax that I can't find anything anymore for the 880 big bore kit. Has anyone done the 700SX pistons in a vmax making it a 9XX? If so what did you use for head gaskets? Those pistons are readily available, though I'll have to have the cylinders bored and sleeved.

Thanks!
 

The problem with the 700 SX pistons is they have a 20mm wrist pin bore. V- Max 750s have a 16mm wrist pin and the 800s are 18mm. This complicates things. I have seen seen some use bushings from 16mm to 18. It’s much better to have the correct wrist pin bore. Either custom pistons or custom rods.
