firstly can i ask why you would want to adjust it ?
or do you mean how to check if the cams are installed properly
after a rebuild,
if you just want to check if theyre installed properly follow these simple steps:-
1 take off the cam cover
2 take out the sparkplugs
3 put the bike in 6th gear
4 if you are looking at the bike from the front, on the right hand side of the engine will be a timing window,
this will have a flat slot in to undo
5 once you've opened the timing window, turn the back wheel
until the T marker inside lines up with the marker on the casing
6 your engine is now at top dead centre - you will also notice
the exhaust cam lobes are pointing towards the front,
and the inlet lobes are pointing the opposite way.
7 there are 4 blocks bolting bown the camshaft holding it in place,
the block on cylinder number 3 (this is the one to the left of the cam sprocket in the cenre of the engine)
there will be a line marker on the block near the sprocket, the sprocket will also have a dot punched into it, these markers should be lined up for both the inlet and exhaust cams.
once this is all checked, make urself a nice cup of tea
and sit and look at your bike, talking to it like i do
