Need a bit of help guys, need some measurements from an early DR 250. The plan (for vinduro use) is to put a DR250 motor with 300cc kit from a GN250 into an 86 RM 125.

If someone has a DR and a tape measure handy I need to know the length and height and width of the motor and the size of the bolt that goes through the swing arm and rear of the motor.
Cheers, Chilly.
