do you have any mates you can borrow a cdi from just to check yours is ok
if not check your woodruff key as they sheer and throw the timming out
dont know if you can get the flywheel off ..or if you would have to get someone to remove it for you but this would need to be removed to check the woodruff
ahhhhh its such a shame as its gonna cost a mint to have the garage guys look at it.. coz they gonna be doin everything we already looked at and they gonna charge you
