Most of the companies out there charge way to much for their labor. I would go to Bob instead and ask him for a WR crank and piston to achieve 449cc.

what is the difference betwen the WR and 06 yfz setup?
one would think that the 06 would be more reliable because they actualy made it for a quad?

well the only difference is the pistons/rod the wr has a small wrist pin and the yfz has a large pin. so yes now people are putting in the 06 crank but a year ago you bid not have a chose

Get the WR from bob the 06 yfz has a shorter rod

[SPANNA36]

has the WR pin proven to be un reliable?
or is it just biger is sfer?
how much shorter is the 06 rod? would it make a notacable difference?
