Hi Paul, If you haven't already, have a good look at the primary and final drive chain. I had a similar noise on one of my bikes and it turned out to be a split roller on the final drive chain. crazy thing was it had to be in just the right orientation to hit the gearbox sprocket and make the clunk. So it happened about every third or forth rotation of the chain.
G'day Paul, been on a couple days ride with mates and out of range of the internet so I'm in catch up mode on your site, yes mate strange sounds in the next videos l hope you have found the problem, cheers mate, Neil 🤠.
Try to see if there's any polished up spots on the rear chain plates. Or is it even something more simple like the rear chain tapping the swingarm pivot with a standing wave. Mine did that when I fitted slightly longer rear shocks. The sound went when I was riding with the suspension compressed.
Chains ,bearings ,etc often get reversed orientated upon reassembly....sprockets get worn..its a black art..Ive always thought a couple of tensioner guides would really help....lay out all the clutch springs and put a straight edge over them..also a fine file clean up clutch basket tines and plate spline ...tabs..with make for a much smoother clutch movement
Whilst running in gear slowly put pressure on the rear brake that'll stop the noise. It'll be the final drive chain thrashing about. As they always make clunking noises when not under load.
Hi Paul, do you have an engineers stethoscope? I find they help immensely in localising odd noises which often send you in the wrong direction. Just a thought.
Alternatively!, old mechanics trick, a piece of wood about a foot long and half inch thick. Place around area you think is the issue, place other end against your ear. Believe it or not works for me every time.
Sounds like primary chain not running smoothly over the teeth. Put a bit of load on it and the chain sits badly one a particular tooth. Just a suggestion. Watching with interest
Sat in my armchair, I did not think it was something hitting the case, it sounded to random and to 'solid' as if its hitting the back of the primary - no idea what it could be though :D I though maybe a clutch spring doing something odd. However cannot wait to see the problem!! Thanks Paul.
Couldn't hear too much from you speaking over the noise, but my bet is still on a starter clutch mechanism not being align properly or getting in a way of clutch basket.

That clunking noise aside,,, it's a lovely sounding engine and exhaust note

Would it be possible to re record your voiceover, I can't hear your wise words
Thanks Paul.
Has it had a clutch conversion, could be an alignment issue?
What's the gear behind the small aly plate for?
That is one of the electric start gears.

Does it have the right number of clutch plates
I honestly don't know as things stand. No doubt a test ride would show up any shortage.
What about a gearbox gear missing a tooth?
Whilst running in gear slowly put pressure on the rear brake that'll stop the noise. It'll be the final drive chain thrashing about. As they always make clunking noises when not under load.
I did that, and it made it worse, but you could be on the right track!
G'day Paul, is the chain knocking on a case somewhere? Sounds like it had my chain make the noise once, cheers mate, Neil 🤠.
Hi Neil, yes, that's what it was!

What's the difference between a motorcycle and a puzzle. A- not all puzzles have a motorcycle.
A normal chain & 4 spring clutch! I expected something a bit more fandangle!
I had a very similar noise on my T120, turned out the drive side bearing had eaten its cage and the balls were all together on one side of the race.
Oooh - we know where the secret switch is now!
It is one of a couple ...

Sounds like a chain jumping a tooth
couldn't hear a word!
Can't hear a word you're saying
I know it's your bread and butter to fix these "restored," machines but do ever think of saying take it back to the twit who sold it?
