1985 YZ250 with air cooled motor????
« on: March 18, 2014, 11:27:11 am »
Don't know why you would, but the price could be right for someone who wants the engine and then sell the rest off  ;)

Looks like a 85 frame, with later model tank, exhaust and other bits, but looks pretty tidy overall and gotta love those red footpegs  ::)

Gotta be a YZ490, or a YZ250F motor? Maybe IT250F/G?!
The "likely" aircooled motors (IT250H+, YZ250G/H) all had side exhaust ports.

Piston Numbers come up as 250YZ C, D, E,F? and IT250 E,F,G Wiseco Piston. look like an YZ250 E/F motor given the size of the ignition cover.

Need engine numbers.

Intake manifold seems to point the carby directly backwards - suggesting the motor isn't from a D/E.

Be good to know the engine #..Looks like a E-F engine to me,... if so wouldn't mind it for a spare engine to tinker with  8)
