A new noise has recently started to pop up. It's a kind of scratchy rattling whenever I'm going over ~40-45mph and I take the throttle off and cruise (clutch isn't pulled in btw) When I pull in the clutch it stops making the noise.

It isnt a steady regular noise it's kind of uneven, random-ish. It doesn't have a metallic ring to it, sounds almost like someone dragging their heels as they walk.

Any ideas? I'm a noob having been riding for about 2 months and I'm still learning mechanical know-how, any help would be appreciated.

 

if it vanishes when you pull in the clutch, id look at your clutch or some major parts related to the clutch. id check out whats under the clutch cover to make sure everythings fine. take it to a professional if you dont have the mechanical know-how. otherwise you're gonna screw stuff up digging into it yourself.

 

I second that. It's definitely some sort of a clutch issue if you say that it disappears when you pull the clutch lever in.

You're learning the mechanical know-how? I'd research a few shops in your area and take there.

 

Clutch!

 

Damn, I kind of figured it'd be something like that. What's the price range I should expect for a pro diagnosis? I'm a full time student so I'm limited on funding.

 

yeah probably a clutch issue, especially if it's a high mileage bike.

however, if your chain is very loose it could repeatedly slap your swingarm when letting off the throttle. chain slack is an easy thing to check before digging further. is the sound coming from the left or right side of the bike?

 

+1 for chain tension... start there... it is cheaper and easier!

 

Yeah my chain is a bit on the loose side. I'll be visiting a friend who has the tools to tighten it. To make sure, is it just loosening the axle nuts then turning the little bolts until the chain is tensioned properly?

 

And the mileage on it is 14k about even

 

yup thats how you tighten it. but make sure you lift the **** end of the bike first. dont do that crap while the rear is still on the ground. its like beating a dead horse. pointless.
