te250 timing chain

[tadgh]

What type of terrain? I see the grass track. In northeastern US we have conditions ranging from clay, short steep hills to rocks and larger hills or low mountains. We may have grass tracks or not depending on the race promoter.

well thats basically what we run too, forest single track, rock climbs, bog, fire road, river crossings etc and sometimes like the picture grass track.
that one was a lot of grass track and pretty much flat out with nothing to cause any log jams but i have ran ones where the course became almost impassable after a while.
if you see any videos of the 2008 wales wec round well thats also typical of irish enduro/hare and hounds

found a helmet cam someone had on:

Mine is all rattly, too. Sorry to hear that the timing chain didn't fix it. I only seem to notice it around idle speeds--anything beyond that, it sounds great, and runs strong. Hmmm...

in talking to George at Uptite he said it was probably the auto decomp doing that and it didn't seem to be a big deal...

I just changed the oil on my 2005 TE450. I checked the three screens and there was 'junk' mostly at the bigger two screens and in the bottom of the engine. I could put my finger in the screen hole and pull 'more junk' out of the engine.

The stuff seemed to be plastic. I assume it wasn't metal as it didn't stick to the magnet parts tray. I could bend the little pieces between my fingers. They were black and pretty thin. Pieces were no bigger than 1/8" x 1/8" and most were smaller than that.

A few months ago I changed the gasket on the tensioner and never released the spring loaded "plunger" or whatever it is called. I then tried many times to kick it over and it was very hard to start. Once I got it started, I rode it for about 10 minutes on the street.

I then check Cafe Husky and found the error of my ways and realized I should have released the pressure from the spring loaded piece before re-installing. I then corrected the problem and go figure, it started right up. I have ridden maybe 4 times since fixing the tension and all seems fine/normal.

So, I assume I had the plastic (it seems) chain slider pinned against the chain for the short time I was kicking and 15 minutes of riding. Could this have ground up the plastic enough to be the bits I found? Could the bits have been something else? Clutch material? I am a new motorcycle 'mechanic' and have never replaced a clutch before so I don't even know what that material is.

Any help is much appreciated.
