KLR Kaboom

Not as bad as it could've been.

'03 650 w/64,200 miles, AKA Booger.
Bought bike with 63k on it and the Doo was toast, it was OEM BTW
I did the Doo and rode off into the sunset.
Today as I was under decel...CRACK! Locked the wheel so I quickly clutched and eased to a stop. We were on dirt.

Drained oil (M1 15/50) looked clean and sparkle free.
The pics tell the rest of the story. Obviously all those Doo-less miles took their toll on the balancer chain.

This engine runs beautifully and has used no oil in the 1000 miles I've put on her. It pulls strong and had no real funny sounds other than some average cold motor piston slap.

All looks OK in the blast zone in spite of the grenading chain. Yes the cam chain shoes are a bit scuffed.

Do the Doo today!

Wow, I'm surprised it didn't punch a hole in the case. Hard to tell from the pics but looks like there may be some sprocket damage. The tension spring looks intact. Is that the long or the short one supplied with the new doo?

Gray-haired riders donít get that way from pure luck.

No damage to the sprockets or the case! The chain however is done! I was at very low RPM luckily!

Good for you, looks like you can get out of that mess for a new balancer chain, (and new cam chain guides).

Reason I asked about the spring is the instructions I received from HT were unclear about which one to use. I have to wonder if that was not a contributing factor, although your bike had an extreme number of miles on it before you changed the "doo".

My thought was to use the shorter one for longevity, as it would be able to provide adjustment for a longer period of time. Never thought it may be overstressing the chain.

The written word is sharper than the spoken. No ill will is intended.

There was likely a floating part. Either an old lever/doo part if all pieces weren't accounted for, or the washer behind the idler shaft was dropped during the doo/lever install.

General note: In the instructions I provide, there are spring selection instructions. Always a good idea to read the directions, including those in the link provided.
all the best,
Mike

Yeah, guess I just kind of flipped after seeing DonD's crash and just "doing my doo". I did check the stretch of the short spring and found it at right at 3/8".

Is it possible to get too much tension on the chain with any of the parts supplied?
