metal rattling in exhaust?

[BlasterX2000]

i got a 2000 blaster with a stock pipe and it has had a loud rattle for a few days and couldnt figure out what it was till my buddy started shaking the quad back and fourth u can hear a piece of metal boucing around in the pipe it sounds like one good sized piece not a bunch of small pieces could it just be the baffle broke off? because i was told it could be crank bearings but it only sounds like one piece but does highly resemble the sound of a ball bearing in a paint can. anyone got any ideas? :-/

Yuuuuuuup. It's the baffle .

it's very possible that the baffle came loose. i would recommend pulling the pipe off and just make sure that's where it's coming from.


another similar sound could be caused by a leaky head gasket.

ok cause at first i thought it was a top end knock but my buddy was messin around and shaking it back and fourth and u can clear as day hear and feel the rattle coming from the fat part of the pipe after jiggling it for a second whatever it was fell further down the pipe and must have got stuck cause it stoped rattling for a bit but i do remmber the person i bought it from saying sumthing about the baffle just figured id be safe then sorry and ask

 

[brandoz28]

yup definitely sounds like the baffle came loose...


easy fix, buy a good aftermarket pipe! lol. you would be amazed at the difference it will make.

yea im thinking about it im a little short on cash right now seeing as how after a new pipe i will need to rejet my carb so i guess for now ima have to figure out a way to get it out. if it aint one thing its another lol

 

[brandoz28]

the only way to get it out would be to cut the pipe apart.

just save a bit of cash, a used FMF setup can be had around 100 bucks if you look around

I cant belive all the sh*tty advice and guesses with the obvious staring you guys in your faces!!!

Thats a definite sign that the MUFFLER BEARINGS are shot!

While you got her opened up might as well check your canooter valve as well its probably shot as well

i see a used fmf going up for sale soon!!! for right around 100 bux

there you go! pick that up and some jets (260, 270, 280, 290) and a few extra plugs and it'll be like riding a whole new machine!
