Here is a new one. I tend to fire the old girl up once a week and ride her through the yard for a bit to keep things moving. Lately I got a rather loud noise from the drive chain. Like every link is rinning over or against something. But only when I put it in gear and let the clutch out. Free rollong in neutral-no noice. Chain and sprockets only 3k old, all is lined up, sprocket solid, tension spot on, chain very well lubed. Slider on swing arm good.
What am I missing?
Cheers
Rob

Some sort of end-float on primary drive from box when under stress of driving the wheel. A wild guess, but front and rear sprockets out of alignment can make any chain fret a bit? There will be a truly knowledgeable person on this site to crack this, then we'll all learn something hopefully.

the only time I have experienced chain noise that wasn't down to 'obvious' reasons was when the chain actually had more wear that expected
it's not my time to go, it's not my time to die
the last thing I want is for my family to cry

Not that I can see. And just 3k old. With Scottoiler.

Wonder if the chain protector has worn through on the swingarm ?

I checked that first. Good beef left on it.
Still doing it. I will give it a long run-out as soon as they stop gritting in N.I. See if anything was just tight and needs to loosen up.

Well, its still there. Getting a bit louder now. And I do not believe anymore that it is the drive chain. It is from higher up. Very audible from both sides. Decided not to ride her until I solved this or got it solved.
Again, it is a clacking sound as if the side of a chain is rubbing on something. What is internal that could make this sound?. Clutch? As it only happens as soon as I let the clutch out? In neutral and pulled in clutch no noise. Frustrating.
Also had a 'failed to proceed'. Will be in another post.
All great fun, isn't it!

Sounds like it might be the clutch basket area from those symptoms.
Nealry every bike or car I've had does the same thing, when in the neutral position and the clutch depressed it's silent, release the clutch you get noise. Often it's a bearing, in a car it's a thrust bearing usually, but on the bike it's possibly loose plates. ?

It's an easy job to pull the side cover off and have a poke about

Thanks. Hoped if I don't think about it it may not be that. Not easy to do where the bike is. No tools or indoor space.

Well,clutch cover off, nothing obvious. Should the center activator thing wobble about?
Plates out, look like new, dead flat, nothing sticking.
All basket parts solid on bearings, nothing worn.
When put in gear the centre hub got about 1/4 turn free spin. Normal?
Apart from that all looks and feels good.
?
Thanks

Would that produce the noise around the front sprocket area?.
Meanwhile I found out that you don't hear the noise if you ride fast enough. So don't expect me to hang around too long.
Going to move her from N.I. to Cornwall beginning October. Will have her MOT'd, serviced and linkeages done, like every two years. If still noisy garage can have a snoop.

Well, mystery solved. It was the drive chain after all. Needed an MOT, passed again, so got the garage to have a look at it. Apparently, the current chain has several tight spots as well as several very loose spots. That causes it to klick over the front sprocket and slap quite violently against everything it runs over and around. Disappointing, as it is only two years old, has done 5k miles and has got a Scotty on it. The sprockets also got more and less worn teeth. Replace all!
The original chain lasted 32k miles! Only replaced two years ago. What make would that be?

Well, first of all - the Scottoiler needs to feed oil - which isn't neccessarily the case. Secondly, age and little use harms a chain more than use. That's my experience (on both issues)

Possibly over tight when fitted, tdm's need plenty of slack despite mot man telling you it's loose.
