Hey all,
Just looking for some thoughts on my NSR clutch.
Something is wearing out and I'm looking to get it sorted soon as its annoying the nackers out of me!
The symptoms are the back wheel still drags the engine even when its ajusted to pull the clutch out as far as possible (from the beginning of the lever travel). It drags a little less when its ajusted like this but having the clutch open/close in the first 1/4 inch of lever travel is annoying to say the least.
The bike has done 13,000 miles but parts have been swapped and changed between this and a donor bike (previous owner) and thus the engine may not be the origional. I suspect the problem could be tired springs/streched cable and am thinking of ordering these two from wemoto.
Just wondering what the difference is between these springs and these heavy duty EBC ones? Worth the extra few bucks?
Also whats the difference between the cheaper steel clutch plate set and the kyoto friction plates? Asside being less than these would they be worth looking at if it comes to plates?
Any thoughts would be much appreciated.
Best regards

Heavier duty springs press the clutch together harder which is good if the clutch is slipping because of too much power. Not really necessary for 99.9% of people and it makes the clutch harder to pull, I'd get whichever is cheaper. Also the complete opposite of what you are experiencing.
A bike clutch has both steel plates and friction plates, they are two different things. If your clutch is slipping then you have probably just worn out the friction plates. If you look at the steel plates currently in there then look for bluing from heat and see if they are straight and within tolerances etc. Might be better just to buy some new steel plates anyway if they are cheap.[/quote]
Sounds like the cable or part of the pulling mechanism is knackered or the clutch basket itself is notched rather than the clutch plates though. If you take the clutch cover off with the intention of replacing bits, inspect and measure the thickness of them first.

Watch that it explains how the clutch works.
If your basket was notched then the plates don't move smoothly and as a result they could bind together even without the spring pressure.
You would need to take it apart and inspect to see if this was the case though, the solution would be a new basket or file the notches out of the old one as a temp fix.
Work your way through the clutch cable and pulling mechanism first however as it is simpler and cheaper to sort and more likely to be the issue.
HTH, good luck . |
