Hello everyone! Will a 1979 CR125R motor work in a 1980 frame? I know the cylinders are a bit different, but if I use an entire motor, will it work?

Thanks!

You cannot swap the entire motor from a 79 to a 1980. The 79 had the exhaust port exiting at an angle. The 1980 exhaust came straight out. The frames were different. Maybe the bottom ends will swap.
