Engine Case

I have a '92 CR250 and my piston self destructed yesterday,
upon disasembly I found that a piece of the piston went through the front of the right side engine case, right at the seam with the left side. The hole is about the size of a dime, my question is, can this be reliably welded?
A local guy says no, but I am living in Mexico, so that wasn't a shock, any help would be appreciated.

Re: Engine Case

I'm no expert, but I seriously doubt it. I doubt a weld would hold once the engine gets hot. Just my $.02.

Re: Engine Case

Not sure about welding a patch into the hole but I'd think it'd be pretty hard to match with the other case.

A new case for your bike is $307.60

Re: Engine Case

sounds like another 'project'

im sure it could be done by a good welder, not some migy

migy: a person who has no experience with an arc welder and thinks they are the shyte.

Re: Engine Case

MIGY: one who uses an Arc welder on Aluminum. OUCH!!! It can be done by an experienced Heliarc welder. It will be cheaper than a new case.
