01'Wr426- Tiny metal chunks in oil/filter..Help...

[dirtbikekid1]

I just changed my oil in my 2001 wr426 and there were tiny chunks of metal in the filter. I put a magnet up to them to see that they were aluminum. There was also some steel dust on my oil drain screw magnet. Is this a big issue? Do I need to rebuild it? It seems to be running fine and it isn't making any bad sounds. Any information will be much appreciated. Thanks...

How often do you change the oil?

How many chunks are we talking about?

How hard are you on the clutch?

It is quite normal to see a tiny bit of metal in the filter, maybe a piece or two.

This seems to stop after a few changes. I believe most of these little fragments come from the clutch plates. My magnet always has the "dust" you speak of.

I just got the bike so I don't really know how the previous owner rode. I think I'm going to ride it one time and change the oil again to see if it is still apparent. Thanks so much for your input.

As Mutu says (if that is his real name CR boy) always expect to find black dust on the magnet, this is normal.

Metal however I think comes from the gearbox dogs. So take it easy on the gearchanges and use the clutch whenever possible.

The 3rd and 5th gears are the achilles heel of the Yammy but can last indefinitely if treated sympathetically

Normal clutch material. You will find flakes in the pleats of the filter too. I suppose it could be a failing ball bearing, but you'd find out soon enough. Its usually just some clutch material.

Be careful dirtbikekid, I just buy a WR400 1998 and the motor do a buzzy noise....I have change oil and notice the exact same aluminium parts in my oil.... after riding a couple week...PAF.... the timing chain have jump some gear and the front chain guard have broked in 3 pieces. when I have do the job I have nitice the timing chain haved grind the inside of the motor, I dont have the choice to change the timing chain, the both guide and a new head gasket....total coast of the job $385.00 and do the job myself. IF I WAS YOU I WILL CHANGE MY TIMING CHAIN ONLY BEFOR IT JUMP GEARS AND DO MANY DAMMAGES. Just change the timing chain is easy just little patience. GOOD LUCK !

I had similar metal bits after recently purchasing the same bike. Approx 3 riding hours after the change, 3rd gear went out and grenaded my bottom end including the cases$$$$$$$.
