YZ/IT250 Motor Differences
« on: February 22, 2014, 05:56:46 am »
Does anyone have any input on the seat of the pants differences from 83 IT250 to an 80-81 YZ250?

pretty sure the IT's are blue and the YZ are white ;D
I have a 83 IT 250 with a YZ250g donk in it and the IT motor's on the shelf  so the differances are
1) electrics for lights (fly wheel etc)
2) gear ratios
3) porting

Detuned yz engine (One or two models back) with a wide ratio gearbox, porting, pipe & a flywheel for more torque less peaky powerband & the obivious cosmetics.
