2003 wr450f engine noinse.

7 posts in this topic

now i have read alot about these engines making alot of noise especially when you have a skid plate attached. i dont have a skid plate, and the engine noise is only at lower rpms. when you get on the throttle the noise seems to go away. it also seems to have a little sputter at lower rpms also going away and smoothing right out when you give it a little gas. it runs beautiful at midrange and higher rpms. now i just bought this bike saturday knowing that it needed some work and i am very new to the dirt bike world so any help or advise would be greatly appreciated.

thanks~

A loud knock from the bottom end is very bad. Mostly noticed at idle.

A ticking sound could indicate a loose valve clearance.

There tends to be a lot of noise from the clutch with these bikes. It is usually nothing to be worried about. Good luck with the bike.

Ift's while lugging it while riding it is most likely drive chain slap.

Even when properly adjusted this bike will have some chain slap.
