It's a 4cyl 250 in wellington, it's not hard to switch off engine in a high gear and roll down a hill...

Not really sure why this guy is getting so much flak on this thread, he seems to have at least a rudimentary mechanical understanding and a decent ability to describe the problem and understand our questions/advice on it; seems like a thing that should be encouraged tbh.

Do the number of clicks per min at a fixed speed of say 70kmh stay the same ,or would it change with gear selection,motor rpm?

as described; the ratio of clicks varies with road speed and gear selection: if i ROLL faster, it clicks faster

If i REV harder (in same gear)-road speed increases and it clicks faster

If i down shift then it clicks faster.

and please, ive been reasonably patient (as i guess many think i should be given i'm new to the forum, and therefor cannot possibly have ANY experience with engines (thats sarcasm incase you dont quite have all cylanders running today))- but yes. IT DOES STILL CLICK IF ENGINE IS NOT RUNNING< STOP ASKING STUPID QUESTIONS IVE ANSWERED THREE TIMES ALREADY--READ THE POSTS< IM HERE FOR DRIVETRAIN ADVICE< NOT TO BABY YOU ON HOW TO READ...

sorry to all those who have been most helpful; but some of your comrades are becoming a burden

You sound like a fuckwit.

Fair enough then. I guess I won't ask about the kerfuffler valve and what colour powerband it has...
Seriously though, if the chain and sprockets are OK it sounds like maybe a missing tooth on either the primary gear or the clutch hub gear. About a million years ago I had an XR500 that had similar symptoms and it turned out to be the primary gear missing a tooth. If it is that then you are lucky, no need to split the cases.

Remove engine

Split cases

Inspect/repair/adjust gearbox/selector system as required

Reassemble

Refit

Ride

That's not very helpful.

It's very simple! You move your clothes to the lower peg only AFTER you've written your letter home unless you are getting your hair cut in which case you get your younger brother to move your clothes to a lower peg for you!

You going soft?

If the clicks increase with a downchange lifting rpm but not speed but doesn't do it in neutral then fault after the clutch. If it does it in neutral while rolling down hill its likely final drive bearing. If it stops with clutch pulled and rolling in gear its likely in the clutch.

I still think final drive bearing when under load due to the started after chain replaced unless its the wrong size chain or sprocket teeth bent over and catching.

Its likely had a stretched chain running with tight spots on that bearing for a long time.

Order a clutch gasket. Remove cover. Inspect
Drain oil and check for metal. Remove oil filter and check it also for larger bits.
How about remove chain and check shaft for movement.
If bearing collapsed enough to be noisy seeing as its sitting in oil then the shaft will shack or the oil seal will be weaping when the bike hot.
Take front sprocket off. Warm up bike and put it in gear.

Anyhoo. I'm quite interested to find out what the issue with the bike is. If I thought it wouldn't lunch itself on the way up the gorge, I'm almost tempted to get this cat round to mine to investigate... Not that I need anything else to work on.
