Are YFZ cases machined to fit?

[Bill Fuller]

I recently put a hole in one of my cases while riding.I have bought a good case from an '04 to replace the damaged one but a friend told me that cases are sold together because they match.

Because they match? Do you think the factory made seperate molds for every case they produce? Or machine each one differently? The one you bought should bolt up fine.

[Bill Fuller]

Thanks for your guess.They ARE mached at the factory.

NOpe, he's right. Well, maybe?

ha, all i know is that you have to buy both of them, cant just buy one.

[BuB400]

The only problem I could see is where the cylinder bolts on, if one side was higher/lower than the other. I've seen motors built with one different case such as your example so I would hardly call that a guess.

you can buy seperate ones and have a shop match them together. I bought 2 different 250R cases, and had my shop match them together. Nothing a dial indicator and a good ol bridgeport can't fix.
