My DR650 died today.

[Squiggles]

Done any mods that might require a rejet?

[Transalper]

When mine broke I was stuck in gear but could push the bike with and without using the clutch. The piston would not go up and down. Couldn't shift easily. Once home (via trailer) we rocked it a bit and heard a chunk of gear falling to the sump. I managed to shift gears a few times and could still push the bike but the piston still did not go up and down. Then it all jambed then it got free again. We never tried the starter button but even if we did I dont think it would have turned over... bent crank etc.
Removed clutch cover, fished out piece of gear then took it all to mechanic which is where it still is.
Happened on the Dusty Butt ride in the middle of the Rainbow.
That has all been said before in Nordies gearbox thread.... what ever that was called.

A train.

[junkmanjoe]

A KLR would never do that??

klr was my first choice, but dr was cheaper.

Hey Joe

PS: Can you guess what the piston is out of?

That piston looks like it's out of a big two stroker, so won't be any good in the DR.
Not a boat and not a train...hmm. Big aircraft engine?

Definitely run out of compression, either holed a piston or bent some valves somehow, you don't always hear valves bending.

Do drs have a decompression device?? maybe look at that, but my guess is the cam timing has slipped, and bent valves.

That piston is either out of a compressor or an old (very)tractor.

[junkmanjoe]

what would cause the timing to move out of place.

maybe a sheared locating pin on the cam. Mind you I don't know dr engines at all, but am an engine rebuilder by trade so have had to look at a lot of failures over the years.

so youd know the KLR pretty well then

I've heard of the auto Decomp jamming causing simular symptoms on the DR, i hope its something that simple

Don't wanna start a dr klr pointless thing' but after 6 months reading kb the engine failure score so far is

DR 3

KLR 0

Saying no more unless provoked.

[junkmanjoe]

easy boys, my toy is broken.
every time we go out for a ride something happens.
mybe the east coast dosnt like the DR very much,

JMJ motor gave up.

wait on bad things happen in 3s

My DR is 31 years old and still going strong. Actually, prob not original engine, but hey, DRs are still good. You probably burnt a valve or fried the coil.
