I know a lot of you guys have the 88mm bore 426/425 pistons in your quads. i am looking to put the 88mm bore weisco piston into my 2002 400ex. My only problem is that weisco says that the piston will not fit on the OEM connecting rod. I asked the guy at LRD racing and he says the wrist pin sizes are the same so it should work. Does the 88mm bore weisco piston fit on the stock 400ex connecting rod?
