Rear Cylinder "thunking" probably the cams...help
 

Ok. Let me start off with, I've searched the forums through all the cam tensioner threads. Mind you this still may be my cam tensioner, i just need to know for sure if i'm going to keep riding it to see if the tentioner fixes itself.

A week ago i was hearing a high pitched ting ting ting ting, coming from only the right side of the rear cylinder. (seems to be coming from the side of the cylinder head.)

Today after a ride, the noise has morphed into a deeper thud thud thud thud. Same pace as before, same place too.

So the question: Are the cams on the right side of the engine?
Why has the noise changed?
Do I ride if for a while and see if it fixes itself, or spend the time ripping out the tensioners? (forums seem to have a bit of debate on this, i just dont want to hurt my baby)

My curvy does this after a top end rebuild on the front cylinder but theres sweet fa wrong with the cam chain tensioners, cam chain, valve clearances etc. After its been running for 10 seconds, it sounds fine, might jsut be the front cylinder firing properly.

Could this be the case with yours? (if it still makes the sound when you are riding along, does it still feel as powerful?)

Honestly I've been affriad to ride it while its like this. I was hoping someone would be able to differentiate between valve noise and stuck cam tensioner. It doesnt sound like a chain slapping.

You COULD always take off the rocker cover (very easy to do) and check the tension of the cam chain. All you literally have to do is undo the three bolts on top of the casing and lift up. Gasket should be re-useable considering the amount of times I've had mine off!! There should be minimal play in the chain but 'some'. This is naturally quantified in the haynes manual. If it's loose or too tight then it would be worth purchasing new cct's. Replacement ones rather. :)

I'm sick to death of cct's that I will be getting manual tensioners in a few weeks/months.
