Lots of nooby questions here, sorry for that!
While I`m messing about with my bike, I thought I would also adjust the valve lifter.
Found this great vid on youtube...https://www.youtube.com/watch?v=9PD38ZaDjGg
Only problem is that as soon as the adjuster arm touches the little tap on the rocker arm it wont budge.
Is there a possibility my bike is fitted with a stronger valve spring or something? the valves move up and down as they should when I crank the motor but I cant move them with a large screwdriver, let alone the valve aduster. They are realy hard.
Whats going on?
