09 KLX250s Clunk when letting out clutch.
#11
I have barnett springs and dirt racer clutch on my 351 klx, the clunk has always been there even before the upgrade, clutch basket looked good to me. I've always assume it's been a drive chain issue, perhaps the feeling of the chains initial friction on the sliders, depending on what gearing you are running.

No, the basket isn't hard to replace until you look at how much a new oem one costs. How you would check it is by taking out all the plates, and feeling the inside of the baskets fingers. Over time they can become grooved and this affects clutch action. Come to think of it, I don't think that would cause any kind of "thunk" when you let the clutch out. Does your clutch slip on it's own at all? Another thing I thought of, how loose is your drive chain. Even though first seem real low to me, the little klx sounds like it struggles to take off sometimes and sounds like I get a little chain slap.

The danger of an over tightened chain is that when your rear suspension is compressed about 2/3 through it's travel is when your chain gets it's tightest. The absolute best way to check is to remove your shock and adjust the chain so you can rotate your swingarm up through the motion. Not practical at all unless you were doing other maintenance, so I check at the back bottom of the plastic chain protector that is mounted to the front of the swingarm. Push the chain up and it should come to about 10mm from the swingarm. Then compress the rear suspension and make sure it doesn't get super tight and then you're good. I don't have a manual, but this is the basic way with all bikes, unless of course you own an ATK 406.
