left hand cam chain tensioner missing ? HELP !

Ok guys, I was out riding on Tuesday next thing I know theres oil everywhere ! the left hand cam chain tensioner cap has come off !! the engine still running fine no rattles i have found it stuck in the throttle linkage now I figured the plunger should be under it looking at the parts diagram BUT I have pulled the cam cover and I am pretty sure the plunger operates on the lower guide from the other side so it would go in before the guides and the cap is just a cap if you know how it all works please let me know I can just put the cap back on and enjoy myself this weekend ???, jon.

Do you mean the 6mm dome headed Allen screw that goes into the back of the left cylinder cam chain tunnel? If so you're golden. Just pop it back in with a sealing washer and go.

If you mean the 24mm cap on the inside of the valley? Lon the LH cylinder this is also just a plug for the hole used to bore the tensioner plunger seat in the other side of the cylinder. This too can be replaced easily but use a sealing washer on it or it will leak.

Reading your post again I think the second option is most likely.

Hi Pete, Many thanks for the reply I should have been clearer it was the 24mm cap took me ages to realize why the 2 cylinders are different I then realized the plunger has to work on the slack side of the chain anyway its got locktight on it now !, the engine was rollerized just before I got it so I guess it was removed then Ive done about 8000 miles on it so why it came undone now is a mystery may bee the heating & cooling has annealed the washer & crushed it slightly who knows ?? panik over any way, many thanks again, Jon.

Hmmm. It doesn't need to come off for rollerising am more likely it was just done up by some limp wristed feeb at the factory when assembled.
