My 2009 AVL 500 Bullet has previously been stripped of its decompression cable. I am trying to restore decomposition capabilities, but the lever on the plate at the base of the valves does NOTHING. I have read where it is supposed to raise the exhaust valve, but a I can't find a drawing anywhere in either the shop manual (AVL Bullet Electra) nor the Snidal (admittedly classic iron cylinder) of HOW THE CAM LIFTS THE VALVE??? Obviously something is missing on my engine, but I can't finds drawing.
Thanks

Portis is correct. The AVL system does NOT lift the valve. It only holds the exhaust valve push rod UP once it has been raised by the rotation of the engine and the rising cam.
I have removed it all, including the switchset lever, from my '08 AVL (it is virtually USEless except for killing the engine). Would it help you if I took pictures of the mechanism and posted them?
Did YOU remove the mechanism or did someone else?
Is the collar installed on your exhaust valve push rod?
Addendum PS: The AVL compression release system doesn't help at all with kick starting if that is your goal. As Ace said, and I hesitated to do, it is a useless piece of shit (except for killing the engine). I kick start my engine just fine without any kind of compression release and it has 9.8:1 CR with horrendous strong Ace valve springs also.
