Although the bikes got a 'service history' in reality its just stamps in a book confirming 'service',no details.

I have changed oil and filter,brake fluid and stripped/cleaned the calipers.

Lubricated the cables and anything else i can see and cleaned and adjusted the chain,,3 times!! what a faff that is.

Im going to change the coolant,which one is it?..car stuff ok?

I have no idea when the valves/tappets need checking or if they have been. So my questions are : when should they be checked and is the process the same as the ten? ...
