So I have a 04 that was stolen and recovered layed over. The bike overall is in ok condition (damaged fairings, levers and whatnot) but the worst damage was about a 2 square inch section of case was destroyed. Ive come across a bare engine case that I can swap all the internals into, but I was wondering if its possible to just swap the lower case over and call it a day? I know that the main journals are in there, and I believe the bearings are matched to the case if I read correctly, so can I get bearings for my replacement case and use the lowers in my new case with my original upper case?

Basically is there a cheaper way to do this than either paying ~1500 for swapping cases+ rebuild or buying another motor?

 

The shortest answer is no. The cases are a machined match pair. Having said that, I'm sure it has been done before with a measure of success. It may all fit and work, but it will probably never be in tolerance by the book and may never be just quite right.

 

Thats understandable, Ive decided to just cut my losses and sell it as is with the parts to repair it.
