What thickness should the spacer plate be??

[stever250r]

If I use the 88 long rod crank, and a wiseco yz250 piston what should the thickness of the spacer plate be?

I think they are different depending on if you use a yz250 piston or an oversized 86 250r piston.

Does anyone know for sure?

im pretty sure the yz plate is 2mm thick and the 86R is 5mm thick. Corey

88 rod with the 83-87 YZ250 piston needs the 2 mm spacer plate. The 86 piston with 88 rod uses a 4 mm plate.

If you need a YZ piston for this set up I have a NEW Pro X kit for sale $75 + shipping. New Pro X kit 83-87 YZ250 68.25 bore

I would take it Matt but I need a 68.75mm
