i juss got a f3 and started it... rode it down the road... and i noticed a chatterin sound... unno wat it is, im not that smart on motorcycles? wat do u think it could be....u can hear it at a idle and low spd coasts

 

Cam Chain Tensioner.

$50 part, there is a $1.50 fix somewhere here on the forums. Does it sound like it gets less noisy when revving or riding at higher speeds?

If so, it's prolly your CCT - super duper easy fix.

 

Hey, i've got the same thing, can hear a little chain thingie at idle and low speed, does that mean the CCT needs to be replaced?

 

Prolly - super duper easy fix!

All you need is an 8mm socket. Just take your side fairings off (don't even need to com off actually), on the right side above the clutch cover, sticking out of the block at about a 45 degree angle (two 8mm bolts).

Install the new one, thread the new tensioner shaft into the bolck just until it makes contact with the chain, start the bike and lightly thread until the rattle comes out of the engine. Once rattle is out, tighten down the locking nut and you're golden.

Just make sure you use a gasket or gasket compound - clean off the old gasket and make sure no debris falls into the block.

Super duper easy.

 

Well he did say "chattering" and not "ticking" so Im not gonna jump on the CCT band wagon like most... Im thinking a dry/loose/old chain...?

 

Well, where is the sound coming from?

From in front/underneath you? Behind you? Old, dry chain would definitely make a clicking sound behind you when you accelerate from a stop.

Bandwagons are fun, hop on one.

 

yea well there is a small sound comin from the rear sprocket area also but i think thats juss either brakes or the chain... but the main sound im wonderin bout is the one comin from like below/front me, kinda around the lower fairins.... it does it both idle and low speeds....might do it at high speeds but i cant hear it cuz the wind and bike and the surroundins

 

It's your CCT dude. Replace that beotch and ride it till the wheels fall off...

Oh yeah, and replace that chain and sprockets

 

well around here its to cold to ride and ****... will it hurt if rode bout 1/4 mile a week for bout 3 months until it warms up until it gets warm and i can ride it everyday? then ill fix it before i ride it everyday?

 

Let's assume we know it's your CCT.

By not fixing it you risk bending valves and creating and even bigger problem.

The CCT works by maintaining tension on the cam chain when there is slack. When the engine revs high, obviously the slack on the chain is reduced, and more tension is created - lessening the need for the tensioner so the tensioner collapses back off the chain. The problem however, is that the hydraulic tensioner that comes on the bike has an engineering flaw that commonly fails and doesn't always allow it to extend again once the RPM's are lowered quickly (backing off the throttle quickly while in high RPM's), meaning the proper tension is no longer on the chain and it is free to possibly slip - throwing your timing off and possibly damaging valves and ultimately the cam and crank teeth (worst case).

The manual tensioner remains constant. You set it when installing and it never moves from that position regardless of RPM's or chain tension.

Bottom line, there is a fix on here somewhere that will cost you around $2. It's worth it to find it. I would but I've written more than I wanted to and am going to bed.

What you want to hear is that you'll probably not damage the bike further by low RPM riding, and it's probably more than safe to assume that. BUT - why risk it when the fix is $2.

Fix it. Plus I'm not sure how you can pull up to a stoplight and be proud while your bike is rattling all to hell.

FIX IT!
