Sound From Left Side Of Engine

I noticed this today when I rode home about a half-mile from the gas station without my earplugs in. Guess one downside to earplugs is that you don't notice stuff like this.

Don't know if it just sounds odd due to the lack of earplugs or if it's always been there and is normal. Maybe I'm just paranoid. The metal skid plate probably amplifies it, too.

I don't know how to describe it other than a kind of "swishing" sound that I presume is the balancer chain: it kind of sounds like a spinning chain, more or less. No pronounced rattle or anything like that.

After I got home, I did the balancer chain adjustment and started it back up and the noise was still there. Last adjustment was about 1,000 miles ago.

My doohickey was replaced about 4,000 miles ago with an EM lever and the torsion spring.

Can you guys hear anything like that on the left side of your engine when it's running?

Don't worry about it. If you're used to riding with earplugs without them you hear all sorts of noise. It's a fairly noisy motor to begin with especially if the valves are loose (like they should be).

Listen to one of the modern 450 off-road motors, talk about fixin' to splode!

No kidding! It went from being a quiet hum to sounding like it was rattling apart and I'm sure that skidplate makes everything sound worse.

I actually believe this is probably the first time in six months that I've ridden it without earplugs.

I'd say you're right and I'm just being paranoid. If something was wrong, it would probably be making a lot more noise than it is.

I coated the top side of my skidplate with spray on rubber coating which eliminated most of the reflected noise. Rattles, squeaks and and other unnatural noises drive me nuts!

That's a good idea. Might have to do the same this Winter.

Remarkably close to my motto, "If it ain't clanking or knocking, it probably ain't runnin'!" All my bikes seem to be remarkably loud when I first start them, but then I get my earplugs in and all is normal.
