ADA Yamaha 1100 & 1200 in a Blaster Conversion Plate.
ADA has made an Extremely nice kit here for the Yamaha 1100 or 1200 in a Blaster!
Billet engine mount brackets to allow the Yamaha 1100/1200 (non-power valve) engine to drop right into a WaveBlaster. Sets the rear of the engine in the same spot as stock, so you still use the stock mid-shaft. Only modification required is to remove the waterbox and can the use a Rad Dudes rear water box, and grind part of the rib from the waterbox tray so it doesn't rub the motor.
