Not as hard as you would think…

• YZ250 Water cooled Engine
• CR125 Race Pipe
• Nerf Bars
• Full Powder coated frame
• 10″ Back wheels
• Contra Sticker kit
• Race Cut Plastics
• YZ Radiators
• YZ Rear Shortened Silencer
• 15t front sprocket
• 39t blue Rear sprocket

Theres still plenty of work to be done, but its at the stage were its waiting for a few bits to arrive, generator coils and a few others..

this was prity much the easiest Conversion that we’ve done at shugtech’s we needed to cut roughly 3/4″ of the right inside section of the swing arm bush, then the engine just fitted in,
we cut of the existing mounts and moved them up slightly to fit the new engine mounts, a great re-weld by Shugtech,

Exhaust:
Cut the top section of the YZ downpipes and weld that onto the cr exhaust and it fitted straight in round the frame.

Hope you enjoy the pics..
