hi could anybody tell me if the 1982 yamaha it250 aircooled engine is the same as the 1982 yz250 aircooled and if they are not the same whats the differance as far as performance and bhp thanks for looking g :

no it was not new so the whole engine might not be original. i think i will try and find a complete engine but i think it might be hard over here as you dont see many early ones!. could i ask you another question do you know if the yamaha yz250 aircooled engines 1982 are the same as the it250 ones 1982 model and if not whats the differance thanks for time gary.

can anybody help me i am planing on rebuilding my old yz125c aircooled 1976 . i took it apart when i was younger and lost most of the bottom end as you do. the engine number is *1F9-006024* when i done some recent reserch on the web the number came back as a dt125f 1976 did they use the same bottom end? when i also looked at photos my engine it looks like the yz one in the photos on the web as far as the cylinder head and barrel are so is it possible it could be a dt bottom end with the yz top end will it go together? and last but not least do you know any good classic mx breakers or where to find a complete engine any help would be very appreciated
