04wr450 low speed engine clatter

The manual recomends an octane rating of 95. Most of the premium pump gas around here is 93. Anyone using octane booster? Other than that, this is the most awesome bike I've ever owned. Blows my CR500 away. Is this normal?

Sounds like your chain, they are very noisy. It still peaks me out every now and then as well. Check for correct tension, I also did the chain slider mod, thats made it a bit better, but its normal

When I first got my 450 it made a loud "CLACK!" noise when I cracked the throttle open... I was positive it was engine noise... but It hasn't made a peep since I put silicone under the chain slider 50 miles ago. That little peice of plastic can make a helluva racket

I have tried different types of foam but they don't last long.
Think I my try a piece of inner tube like others have.
I think the 05's have something soft under the chain slider from the factory. A retrofit to other years???

I took it off turned it upside down apply silicone, very thickley,smoothed it out,
let it dry and shaved off excess.It was a good 4 or 5 mm thick the whole length.
Worked for me.

Do you have a big sump guard fitted, they do reflect the noise upwards for sure. BUt my engine is noticeably noisier now than in the 1st 500 miles. Check the clutch nut is tight and the locking ring is fitted correctly, they have been known to come undone. Mine seemed ok, so I am still mystiifed! It si not the drive chain as it is noisy when the bike is not moving at all.
Camchain, maybe? Valves, maybe too, but at 1000 miles.......?? Hope not!
Only thing I had done prior to the ride when it became noisier was change the oil to Silkolene comp 4. Same weight as my putoline stuff, but maybe a little different when up to temp......???
If you search on the engine noise, clutch, you should find the post about the clutch nut. its about three months old as I recall and was either started by or solved by a guy out in slovenia I think?

Now take the bike back home and tighten your chain properly and the noise will go away.
I have over 4000 miles on my 01 WR426 I have the adjust my chain rairly, but that noise is a sure sign.
BTW I still have my stock chain buffer and its not even close to worn out.
