removing bike engine sprocket
whats the best way to do the above? service manuals say sick the rear brake on and undo it but as the engine isnt in a bike i cant do that.
im going to give it a go with mole grips on the sprocket and see if i can get it off that way but am a little bit doubtful that will work. only other
option i can see is put it in gear but dont want to damage the box.

Put it in first and use a windy gun (or electric equivalent). You won't break the box.... 
Spin 'er off Well...

Make a chain wrench to fit around the sprocket. That's what we used to do many moons ago.
Tell them about the bent treacle edges!

Oh believe me, you'd have to be properly cack-handed to do any damage!

I made like a Y shaped bracket to hold the sprocket then got the engine into 2nd gear and used a masive breaker bar.They're on real tight.Not to
teach you to suck eggs but you have noticed the washer with the bent up sides haven't you?

:D:D
is your airgun 100BHP???
how would you damage the box??
only thing i can imagine is the engine spinning arround...
i would use a piece of chain... welded to a long bar.

I took mine off last week purely by sticking in first and undoing with a spanner - they are not generally hugely tight I think

With my R1 in neutral I wedged a bit of wood between the sprocket and the case and used my battery impact driver on it.
It came off really easy.
The R1 has a Tab washer that has to be released first though!
