Valve timing

Post by Mossn »

Hello,
I am having troubles checking the valve timing of my bike, I don't really understand what the manual says, that's why I would like to ask you.
I would like to know if the red dot on the camshaft pulley is well placed, the dot is (up) in front of the crankcase mark, the exhaust valve just closed and the inlet valve is about to open.
If I understand the manual, with this position of the camshaft I can turn the crankshaft to put the PMS1 mark of the flywheel in front of the crankcase mark. Then I have to turn the flywheel of 24° clockwise and fit the belt.
Am I right or wrong ? If wrong can anyone explain me where I am not right ?

All the best,
Nicolas

Later bikes (electric start? plus X2 Kanga's etc) are timed using the center of the cam pulley - hence the reason for the rubber bung in the electric start casing?, and not the mark on the crank case, so it depends on the age of the bike.
No need to move anything when fitting a belt unless the engine has been apart.

This might help but check everything first.
