hi all, i got a big red 200es right now, good condition. i can get a hold of a 250es motor. is it possible to swap out? its an 85 motor. i do believe it is shaft output for drivetrain. can i swap my sprocket parts on the 200es motor to fit the new 250 or is this impossible? is there any possible ways to get the 250 motor to work with my sprocket driven big red?
