Timing question

Postby vrlpete » Wed Sep 02, 2015 10:54 am

I have an interesting issue with my 82 asp. When checking valve clearance, my timing marks are opposite. Instead of position one on the crank to check cyl 1 it's position 2. As I've got 15k mi on this bike in this state I assume it runs 'ok' like this. Sounds like I just need to pull the timing belts and turn the crank a turn with the valve adjustments backed out. Sound about right?

Do not......change the timing belt position if it's a running bike...
You may have mis-information somewhere...

Timing marks are specific.When T1 shows up,cylinder #1 is at top dead center..

Take note....
This T1 mark can be on the compression stroke when the plug fires or at the end of the exhaust stroke..
You set the valves when the engine is at the top of the compression stroke.

T2 shows up the same way for the opposite cylinder..
Cylinder #1 is the front right cylinder..#2 is the left front one..
You can look at the marks..T1 on the flywheel...left and right cam have a "up" position and side markers...If there wrong(on the bottom),rotate the crank one turn to bring them upright.
One rotation of the crank is one half turn of the cam.
Check the T1 against the "up" mark and side marks..One tooth off is too much...3 teeth off and valve damage may occur.
