Thats brilliant advice, I'll remember that. Funnily enough er indoors mentioned doing something similar but I told her to be quiet and go back in the house.

Most of the torque are over 20 arent they, so I guess I'll need to get one of the bigger wrench's.

Were you able to shed any light on the chain roller? Maybe I should just go along to a dealer and check out the free play on the one in the shop!

Thanks
