125-200cc 91 WMX 125

Hello all. I just picked up a 91 WMX 125 basket case for $120. The left lower engine case is cracked and I'm sure the engine will need rebuilding from the ground up. Definitely need new steering head bearings also. Also the subframe is tweaked. There's a straight one on ebay for $103. Does that sound a little pricey ? My goal is to restore this thing but I'm not sure what I've gotten myself into lol. The suspension will need freshening up but is pretty solid.

Anyway to make a long story longer whats a good parts source for this thing. Used is ok.
I'll try to get pics up soon.

ebay and halls cycles for the most part. Check ebay.co.uk cause they have a bunch of parts too and alot do international shipping
