Are these adjustable, or automatic? If automatic, how can I make sure the tensioner is working? I'm getting some engine noise/vibration that I didn't hear before, especially around 4000rpm. Want to make sure I'm not i danger of the timing chain skipping teeth. Thanks, Phillip

 

its automatic but i cant tell you how to tell if its working sorry

 

Mine is missing the bolt that goesin the center. Does this affect anything? Thanks, Phillip

 

i would tink that the bolt is nessesary how many miles have you put on the bike like it is?

 

my question is where in the motor did the bolt go.

 

it couldnt have went in the motor

 

as I understand, the bolt is a plug. Correct?

 

i cant remember good enough to tell you for sure but i think you are right

 

the bolt is a plug under that plug is a spring that pushes a small piston inward.that lil piston has locks etched on it"lil teeth" so it cannot back off,no bolt equals no tension but in most cases the teeth will hold inward unless you depress the lock,my question is'nt where the bolt went,where did that spring go" it must came out like a rocket it's very rigid.by the way nothing can go in the motor.it only goes one way.............
