Hi Pleiades

Thank you for your swift reply.

I had a little wiggle of the sprocket but seemed ok, I'll have a proper look tomorrow.
I'll have a look at the throttle cable too, does the manual show how much play/lever movement before it engages?

I must say, I've not emptied the oil breather pipe yet and there's some oil in it, i'll at the filter and plug. Just emailed Kev, hopefully I'll get the controller before I head off to the continent.

Cheers
