Howdy,
The crank in my 2000 GasGas EC250 has about 0.050" (estimate) endplay. This seems like a lot. What is normal for motobikes my trials bikes usually have almost none. I was tearing it down because it was making a [bearing?] sound on the front left, behind the water pump. Also, I plan to put in a balance shaft. I was told the balance shaft install is not as easy as just opening up the casting where it is machined to hold the bearings. Anybody have any experience with that?
Doc
