I am in the process of rebuilding the engine from a 240 pro. When I originally removed the flywheel cover it was half full of gearbox oil and I was unable to acertain where this had got in.
Once the engine was stripped, I found that the kickstart shaft had no o ring or for that matter, no groove for the o ring to fit into. Im pretty sure this is the cause of the problem but why wouldn't the kickstart shaft have the groove ?
I have looked on http://www.r2wtrials.co.uk/html_files/fantic.newarrivals.html and the shaft there is exactly the same as mine (ie. no groove)
Anyone have any ideas ?
