Excess Noise??

11 posts in this topic

:) Installed the E-Line carbon fibre skid plate on my '03 WR450 and it seems that it is reflecting engine noise back up...New noises that I did not hear before and the skid plate is the only new thing I did that ride...I was wondering if anyone else has noticed the same thing after installing a full carbon skid plate????? :):D

Thanks, I did not install foam between skid plate and engine. Should it help with noise?? I did not as i thought it would be easier to clean dust out. Before skid plate i got the pipe guard. It has paid for its self over and over...

I hear that carbon skid plates don't bounce as much noise up as a metal skid plate. I have both. Carbon on my 2 stroke and Metal on my 4 stroke.

Either way I'll take a little extra noise for the extra protection they both provide. I think foam will help and also keep crud from getting between the plate and motor.

Spray paint it. Might get a little crunchy when it dries. Or soak it in black dye. It's all in the details.

What works great is butyl tape sometimes called "ribbon sealer" and its made by 3M. Same stuff they use to seat windseilds in. Its usuallt comes in 3/8", you can make it smaller by stretching it. Of course, it comes in a 15 foot roll. Only drawback, but it will hold it quiet!

How many miles do you have on this bike? I think at around 3000 miles or so I started hearing things. Turned out to be a loose nut on the crankshaft on the clutch side. You can check it by removing the small clutch cover with the bike layed over so you wont even have to drain the oil. You will need a flashlight and a screwdriver to check the pinion nut and gear which sets just in front of the clutch basket. If the nut is loose you have to remove the side cover to tighten. I used loctite and retorqued and had no trouble since. The engine does make noise, with this nut loose wow! I think the noise changed when I pulled the clutch lever in?

I've found that skid plates are great noise reflectors on every bike I've owned!
