Clunking sound from stop during acceleration

My 2009 Wee has recently started to make a clunking noise as I accelerate from a stop. This is not constant. It sounds like it is coming from the rear wheel. I was thinking the rubbers in the rear hub or the wheel bearing, but everything looked and felt good after I removed the rear wheel. I don't hear the noise with the bike on the center stand when I release the clutch. IE no load on the rear wheel.

It sounds like the noise goes away as I accelerate, but that could be other noises drowning it out. It does seem to be worse at the end of the day after 3-400 kms.

I read about the clutch making noise, but it doesn't sound like the noise is coming from there.

Any ideas are welcome!

I have resolved every issue that this bike has had with the help of this site! Thank you! This bike is less than 1000kms from Ushuaia and was ridden here from Las Vegas NV. With the help of StromTroopers!

I had a noise like that. I thought my transmission was eating itself. It turned out to be the chain wearing into the teeth of the sprocket and getting stuck on it. The crunch was the chain roller breaking free of the ledge on the sprocket tooth.

If you lube the crap out of your chain, does it change th noise?

Did you mount the rear wheel correctly? In particular, did you line up the swingarm with the slave cylinder mounting properly? They need to slot together to transfer the torque loads induced by braking.

Chain and front sprocket. Lots of wear can hide behind that front cover. I was amazed at how much smaller my front sprocket was when i checked it.
Those parts do wear!

Agree with chain/sprockets, and if your rear sprocket carrier was easy to pull out of the hub and easy to drop back in.....the rubbers are worn out.

Red face Thanks for the help

The noise occurs after I have been riding for a couple hours. The chain lube I have now is very sticky, and the rubbers are definitely worn.

As soon as I know where I will be for a while I will get new rubbers, chain, and sprockets sent down. For now I will keep the chain clean and try to find some different chain lube. I will be in Ushuaia in a couple days.

This is an incredible part of the world! I will try to get some photos uploaded provided the wifi doesn't crap out!

Thanks for the help!!!

Yup. Almost certain it's your chain on its way out. Look for a kinked link and that's your culprit. That's the sign my bike gives me when it's time for a new one.

Raise the rear wheel off the ground (centre stand/hoist or something safe) then run the bike in first gear and watch the chain. The chain should run smooth with no vertical movement, if it intermittently leaps about and 'stutters' then there's your problem, a stuffed chain. And yes check the cush rubbers, play in them will ruin a chain in no time. You can repack them with old inner tube cut into rectangles, plastic milk containers are also pretty good. And of course there's no use putting a new chain on worn sprockets.

While this is a good way to inspect the chain, USE EXTREME CAUTION when executing this because tools and FINGERS can quickly be eaten by the chain entering the sprocket, way faster than you can pull your hands away. I'd advise against running a bike in gear with no rider unless absolutely necessary

Alternatively, put it in neutral and spin the wheel by hand; chain issues won't be made as obvious but it's safer
