just picked up my r1 engine today.im sure ill be asking loads of questions from here on but just a few to get started
1 does anyone have any dimentions for a engine cradle(or photos)
2 how far back do you mount the engine
3do you use the prop with a mounting in the middle in the centre

Cant help with 1.

Mount it as fr back as possible. The alternator cover will just miss the passenger footwell by about 20mm.

Yes the prop is a two piece unit.

i went further than that and took 6" out the pass foot well to get it as far back as possible..........

Position yr engine and build a cradle to suit............

does the sprocket have to go in the centre of the tunnel opening
