I got my 01 YZ250F project bike taken apart and found I dont need a crank but it dropped a valve and the head is in bad shape. Ill need a new piston and head assembly. I have found a few hits on Ebay but they look used and abused and look to need a servicing themselves. Is there any shops, salvage yards, etc that I may find an 01-04 cylinder head at a reasonable cost? Prefer to be complete, although cams are not necessary as I have hot cams to go back in.
