KLR Guru's Help needed

To start 2006 KLR 25,000 miles. I am getting noise around the front sprocket. It sounds kinda like grinding or the chain running along the guide but it grinds stops grinds stops. It is more noticeable at low speeds but suspect its just covered by engine noise. I can coast with the clutch in and it continues to happen but the bike rolls smooth. When accelerating the bike feels like it has a flat spot on a tire. I did the doo hickey years ago I have also changed the chain with a RK along time ago and recently changed the rear sprocket. The motor sounds strong and isn't missing so I suspect the drive somewhere. I'm thinking maybe the output drive spacer. If it is are they a pain in the arse. I'm no mechanic but do my own tires, brakes and own tools. I ride about 80 miles a day and hate to have my baby acting up. Any advise is appreciated and welcomed. Thanks for the great forum

Get a pair of tweezers, get down on your knees, and start grabbing the rollers in the chain and wiggling them. They should spin, but they shouldn't have much fore and aft or side to side play in them.

These things do not always wear evenly. It's not unusual to find worn roller bushings in one section of the chain and, a foot away, roller bushings that are pretty much OK.

The symptom you describe is similar to what this condition will produce, so it's worth a look. Unless, of course, you just replaced your chain. ;^)

You should also check for chain tension - spin the rear wheel and look at the slack in the chain. If it changes it's another indication of a worn chain, or of an improperly adjusted new chain (there is often some eccentricity in the sprockets. If the chain is adjusted too tight when the chain is most slack then the eccentricity can cause a tight spot).

The kind of wear I'm describing is shown in this post.

Welcome to the forum!

Checking the chain none of the pins rotate. There was one link that the pins were protuding more than any of the others. I can't get another until Monday or Tuesday but will start there and keep going. Keep you posted

I think you misunderstood, or I mis-communicated. You want to grasp the rollers and see if they have a bunch of play in them, not the pins.

In this picture:


The roller rides on "Special Oil Impregnated Sintered Bushing". Now, this just happens to be a specialized photo, but our motorcycle chains look the same. That bushing that the roller rides on can wear quite a bit and allow the bushing to have fore and aft play. That's what you're checking for.

In this photo:


The bushings are at the center and you can see the grooves worn in them. The roller it self wears similarly on the inside, creating a whole bunch of slop.

By the way, how many miles are on your chain and sprockets?

The chain was replaced probably 10,000 to 12,000 ago along with front sprocket the rear about 2,000. I did the rear brakes and discovered the rear was shot. Actually it was about a week after the change the trouble started at first I thought it was the brakes dragging.

I suspect a new chain will solve your problem.

Get it up on a motorcycle jack or some concrete blocks so you can idle the engine in first gear and watch and listen to find the problem.

I have had the bike on a jack and the sound is coming from the front sprocket area.I haven't had time to work on it the last couple of days but because of the valued opinions I have gone ahead and ordered a chain. I will keep you posted and again thanks.
