Hi There, I was hoping someone out there may be able to help. I'm restoring my 1978 Yamaha XT250, my first project of this nature. The engine itself is in a terrible way and its going to be more economical to buy another one. I have found two today, one taken from an xt250 with a round swing arm profile and the other newer one from a square swing arm profile. Will the newer engine fit on my bike ?. I dont know what year the swing arms changed, so cant date the engine & the chap selling it doesn't know. Any help in this area would be great. Also if anyone could recommend other places to pick up engines i'd be very grateful. many thanks Rupert
