CCT's done but the rattle is still there; Ideas please?

[JIMMYJAMES]

Only me again, sorry for being such a bore!

As the title suggests the manual CCT's are in and set to the correct tension but there is still a rattle noise at idle coming from the clutch housing and lower rear cylinder area. I have done a search and most of you said it disapears when the clutch is pulled but mine dosent. When the revs are lifted to about 2000rpm and above its not noticable but it just doesn't sound as i would like it to at lights and in traffic. Should i be worried? Any suggestions please?

Just off to give it an oil change to see if that helps.

Bump

Oil & filter change done, no better.

Guessing here..... if it's not the cam chain the only other one there is the oil pump chain.

But the rattle may not be caused by a chain, its hard to say without hearing it.

Its louder on the clutch side if that helps. Where would the sound be coming from if it was the oil pump chain and can anything easilly be done with it? Just thinking maybe i could have a listen with a screwdriver if i knew the general area.

Thanks for the reply phil-V-twin. I'm guessing from the lack of replies no one else knows what it could be or can offer me re-assurance?

If it's still rattles and you are sure the tension is correct, then the chains are stretched too much for the CCT to tension them correctly. Depends on how many miles you've done I suppose....

I'm no expert on the manual CCTs so don't know the correct tension...

[goody]

Any chance you could film / tape it then put it on youtube and post a link to it?

[JIMMYJAMES]

Never done it before but i will give the you tube thing a go later.

Its done 25k miles they are not over tensioned as they have been done as directed before. Finger tight until resistance half turn back and lock it off. It all seemed to line up on the timing marks when i fitted the rear one.

After all the messing you've done with the engine I’d be balancing the carbs first before I started panicking
It could just be a bit of backlash your hearing

Hope it works ok, not the best quality but it will hopefully give you an idea.

That clip is a little too distorted to be useful, it sounds like your exhaust is blowing! ;-)

I didn't want to scare you but my mates 600 SRAD had a rattle that dissapeared under load, either when revving or riding it. A new CCT didn't help which suggests the cam is too loose. Hopefully this isn't the case.

Sorry can't help any further....others wil though

Thanks for giving it a listen bud, the exhaust isn't blowing so i can cross that one off the list. I will roll it out of the garage tomorrow and give Youtube another go. would have done it tonight but its pouring with rain

with warby here, balance carbs first. is noise there with clutch in/out, noticable when ridden? is it a clatter or regular clack, or is it a thunk type knock, is it there on over-run, is it tinny..... just saying very difficult to diagnose but this list can give a pointer. are all timing marks aligned as in the workshop threads?

Thanks for the reply.

The noise is there regardless of clutch in or out, it is only really noticable at idle. The noise isn't tinny, i would describe it as a clatter and the noise is constant at idle (almost like a tractor but no where near as loud) and its not apparent on overun. I didn't check the front timing marks but the rear cylinder marks lined up ok when i fitted the CCT's.
