Anyone notice a rattle after Scotts damper install?

I just got my Scotts damper and installed it this afternoon. I believe I did everything correctly, but there seems to be a bit of a rattle when I'm starting up in first gear at pretty low revs. I never noticed it at all before the damper.

I also greased the pin pretty well, and tightened down all of the screws pretty tight.

Is this normal?

Re: Anyone notice a rattle after Scotts damper install?

Before they modified the mounting bracket, yes. You may have one of the earlier mounting kits. Check the very front tab of your gas tank. It may be coming into contact with the Scotts mounting bracket. Scotts slightly revised the bracket design after people complained. Don't worry, it is easy to fix it yourself.

Normally, the gas tank is isolated from vibration by rubber mounting points. If the tank is hitting the bracket, it can rattle and amplify the noises from the motor. If the bracket is close or is hitting the tab, you can fix it. Remove the damper and the bracket piece that goes over the gas tank bolts. Use a file to add some clearance right where it contacts the tank tab. A small notch is enough, and it won't hurt the strength of the mount. My Scotts mount had the same problem on my 929, and this fixed it right up.

OK, after fiddling with it a bit last night, it seems it's probably either the slot where the tower pin slides in the damper. Doesn't seem like there is much to do about that.

You might want to recheck the stem nut and the setscrews to make sure they're all properly torqued. The pin shouldn't rattle.

I'll check the bracket clearance on the tank. I didn't notice it being a problem earlier.

I also checked the stem set screws. They all seem plenty tight.

Thanks.

It may only hit the tank when you are riding. Look to see if there is daylight between the bracket and the tank tab. When sitting static, the parts were barely even touching, but closer inspection revealed that the paint was chipped off the tip of the tab. You might need to remove the mount to check properly.

Re: Anyone notice a rattle after Scotts damper install?

Doesn't look like anything's hitting anywhere. I assume I got one of the newer versions. It's annoying, because I can only hear it when I'm riding and when it's going through certain rev ranges, but I can't pinpoint it with my helmet on and paying attention to the road, etc. Then when I stop, everything seems really tight and locked down. Not sure what it could be.

Re: Anyone notice a rattle after Scotts damper install?

When ever I got a rattle it was because one or two of the set screws has backed off alittle. When you grab the scots and twist it, does it move any on the bars?

No, it seems to be very solid. One thing I noticed this morning is that when I heard the rattle I would take my left hand off the bars to try to press on this or that to see if I could locate the problem, and the rattle would go away as soon as I took my left hand off. Then I figured out that it seems like when my left hand was on the grip or even pushing forward it would rattle more, and when my left hand was off the grip or slightly pulling the bar toward me I didn't hear it. Weird.

I'm going to try to retighten everything tonight.

One other thing, I noticed that the stock bar ends are a bit loose once in a while. It seems like I could overtighten them pretty easily, and they don't want to get too snug. Is that normal?

Re: Anyone notice a rattle after Scotts damper install?

OK, so I think it was my clutch lever. It was adjusted a tiny bit too loose, and so when it pulled back when you release it, it wasn't quite pulling up tight against the stop, so I think it was rattling slightly. I readjusted it slightly tighter, went for a buzz around the parking lot and that seemed to do the trick, but I'll know for sure after my next ride. If that fixes it I'll be very happy that the damper is installed correctly!

Well, it wasn't the clutch lever. Dammit. I can't tell what it is. I wonder if I've overtightened something? Everything feels very solid. I don't really feel like taking it apart, but I suppose I better.

The thing that bugs me is that I can't hear it clearly enough with my helmet on to figure out where it is coming from, and I can't pinpoint how to stop it.

Get the bike at the RPM things rattle at and just start grabbing everything you can one by one till the rattle stops or changes. Make sure you grab your keys and lock also, mine rattles now and then.

Ya, I'll try that. It only seems to do it most of the time though when the bike is moving. It's very odd and quite a bit annoying. I'm also wondering if the collar part (with all the hex screws that goes around the fork nut) is seated so tightly that it's vibrating against the top of the fork?
