I feel a thump

This only started happening a week ago, and I have a strong suspicion that it is the chain and maybe just a stiff or frozen link. But when I decelerate, ONLY when i have the clutch pulled, I feel a repeditive thump or vibration. I thought maybe it could be the wheel but the chain seems more likely.

For the imagination impaired, it goes like this

FAST ='s thump, thump, thump, thump
Slow ='s thump,,,,thump,,,,thump,,,,thump,,,,thump

It is not very noticeable, I can feel it in my left foot and barely hear it and like I said, it is only when I am rolling with the clutch pulled. If I engine brake I cannot feel it.

So, magic pool of knowledge.... what is it?

You do keep the chain properly lubed and lube after any wet ride?

Did you check for a screw in the tire?

You might have to inspect the chain link by link.

Put it up on a stand and spin the wheel. Should be easy to tell if its the chain.

well chalk me down for the dumbest question of the day.... thanks twowheel... it was the chain... i had cleaned it too well I guess and also I think had it too tight. So I applied my favorite lube TRI-FLOW and it is gone.

so the score goes:
common sense - 1
BAMF - 0

In my experience, that thump is most likely coming back. The lube temporarily will hide the symptoms but once the chain is pooched, well it's pooched. I'm not trying to jinx you and I hope this isn't the case for you. How many miles on the chain now?

And also: Just how well did you clean the chain?

If you used aggressive solvents and a steel brush, you probably damaged the o-rings that hold the lube. Once that happens, there is no more captured lubrication for the chain and it is done.

2600 miles, lubed and cleaned the chain at 850 miles, 1250, 1410, 1600, 1950, and 2546.
I used wd-40 sprayed on a rag and would wipe it down clean. And then apply PJ1 chain lube.

I seriously doubt its a gonner... this early in the game. And even if it is, it would be a warrantee'd item since I documented my service, right?

i never sprayed any solvents on the chain, nor have I ever spray WD-40 directly on the chain. Always on a rag and then wiped off the excess.

This is what I used to clean the chain a couple time, before i started with WD-40. http://thebikeworks.com/product/pedr...3024-qc581.htm

again, NEVER putting it directly on the chain. I think it had to do with the chain tension as well as the chain being too dry (not enough lube) cause once I loosened it up and relubed it, it is gone now.

a factory chain has no master link right? So if that is true they have to cut it off... and if that is true, why couldnt then just use a master link to replace a frozen link?

You're right, with that low mileage I'm sure you'll be fine. Happy trails.

i do have a quick question about chain tension... do you measure that 1 inch of play with the rider ON the bike? Cause that seems to make a big difference in the slack.

Chain slack is measured with suspension fully extended. Check how the tension varies as you rotate rear wheel, and adjust it at its tightest position.

so called me a motard but... when you say fully extended do you mean like up on the stand or fully compressed like with the rider on the bike?

Fully extended as opposed to fully compressed, in its tallest state, with the rear wheel furthest away from the fender, and the axle at its lowest position... Up on the rear stand, see if its fully extended by trying to lift the rear up.
