yz 250 engine drawings

[vasvar82]

I own a 2000 wr 125 husky and have had several problems concerning the engine reliability and parts supply and high cost (mostly around the exaust valve and the clutch basket). In order to solve such problems i was thinking of installing a yz 125 or 250
engine. I know the 125 engine fits whith minimal frame modifications (I tried on a 97 125). Unfortunatly i cant find a 250 engine to try on my bike. Does anyone know where I can get blueprints of such an engine so that I could see it's external dimensions? Any other suggestions of a solution would be apreciated. Thanks!

Still waiting...?

You'll be waiting a long time. The factory won't let those out and anyone who's done the work to draw them won't be giving them away either.
