250r stroker question

[fenix0069]

What spacer plate do i need to run a +4mm stroker crank with a 87 long rod, 87 piston setup. Has anybody ever run this. Kinda trying something new.

Talk to AndrewRRR, or airheaddunner, they both know whats going on, I should but i dont know enough info to be passing stuff on just yet, I would think a 1/4 inch plate, but Im not shure, I run that on a 330 with a 350 crank, Im not shure of the lenght differance between the two.

2mm, with the 4mm stroke increase the piston will travel 2mm higher than stock as well as 2mm lower in the cylinder when the crank rotates.....

Sparks sells the .080" spacer plate. I guess thats the one I need since 2mm is about .078"
