Hey, fellas. I've got a problem that I need to troubleshoot real quick.

My friend recently reached the 6000 mile mark on his 2007 600RR and I've been helping him do an oil change a few other things. One of these other things was tightening the chain. To make a long story short, the drive chain is now making a rattling sound while the bike is at even low speeds and increases as speed increases. I'm fairly certain this is not the cam chain rattling as we did no work to that area. I've definitely heard this sound before but don't know how to fix this. I don't think it's the chain as it only has 6000 miles and was bought brand new. This would also likely rule out severe sprocket wear, but I'm not really sure what I'm talking about. Any help is much appreciated as my friend already had a tree land on his car and his computer crash. Thanks for reading.

We basically only tightened the chain, then realized the alignment was off and messed around some more and eventually ran into this problem.

That's the thing. We initially tightened the chain so it was within Honda specifications. Then we realized the rear tire was tracking to the right and adjusted the screw sets accordingly. However, my friend then decided the chain was either too loose or too tight for his liking and we messed around with that some more. Thanks so far for reading, slaps. I'm glued to my computer trying to help him out. Poor SOB is trying to find answers on his phone after his computer crapped out on him a few weeks ago.

We've been trying to find better ways to align the rear tire than the ticks on the swingarm as they're apparently notorious for being inaccurate.

We've attempted the two "string" methods only to find varying results.

We also noticed that the way the chain lines up on the teeth of the sprocket might be another way to align the tire. Is this plausible? We tried this a few different times only to eventually get part of the chain towards one side (chain lies on sprocket with a lot of space to the right) or the other (chain lies on sprocket with a lot of space to the left). This leads me to believe this method might not be accurate, but at this point we're kind of puzzled.

Thanks for the posts thus far, please keep them coming as my friend needs this bike for work.

I understand you're just covering all possibilities and definitely appreciate that. But yes, the chain has two or three coats of proper chain lubricant. The chain was even degreased, washed down with water, then relubricated and our current problem arose well after this was done.

With the rear wheel down on the ground, how would you go about adjusting the rear tire to align it properly? How do you (slaps) normally align your rear tire, with the gauges on the swingarm?

yeah i used to use the gauges. i still do the same method with the Gilles chain adjusters.

i jus loosen the axle nut, then tighten one (left) side to one mark. then tighten the other (right) side to the same mark. if its too tight or i cant get the other side to match...then i loosen the left side a little and then try to match the right side with where its at on the left. i do this til i get it to match up and the chain is within specs. then tighten the axle nut and recheck the slack. if its all good...then i torque the nut to 83ft/lbs. go for a short ride and recheck the slack again. then call it a day.

Degreased with what?
Washed down with what? (high pressure)

This process isn't that complicated. I definately appreciate people that what to do the job right and maybe even better than Honda recommends. You can never be too accurate.

However the flaw with what you're doing is that the rear sproket has 2 things holding it. One bearing through the axle and a bunch of rubber pieces. Even though everything is held pretty tight, I doubt that it will be more accurate than the marks on the side of the swingarm.

Here's my guess on the noise, you used solvent or something on your chain to clean it. Then pressure washed it and re-lubed it. Using a pressure washer will remove lubricant behind the o-rings. Spraying chain lube on it will not penetrate that far back into the chain. Chain lube does help your chain but it is nothing compared to the lube under the o-rings. ( I used a non o-ring chain on my track bike and lubed it after EVERY session, It lasted 6 track days)

I hate to say that I think your chain is porbably junk. Your chain has to be either extremely loose to make rattling noise (which is more likely to jump teeth ) or your sprokets have to be out of allignment pretty far. (the swingarm marks are close enough to keep that from happening)

I would suggest wd-40 to clean it, it will disolve the old chain lube and also doesn't hurt anything. Then wipe it off. I know it won't clean your chain perfectly but it depends on how much you want to wipe. Then it will fling off a little too after you ride but I haven't thought of anything better that won't hurt anything.

Sorry to bring this back to the top, but it turns out the chain was too tight (according to the mechanic my friend brought it to). The noise has lessened and the bike appears to be running fine. Thanks for all the help and information and a heads up to anyone with a similar problem.
