going to be politically incorrect and ride my klr for the fun of it.

Jeff - I think part of the confusion is I'm talking about two KLRs. Mine and another guy's I'm servicing. I did the torsion on his 3k smiles. Mine I did a few years ago around the 3k mark as well. If you remember, I did it right before a trip to Baja with my brother who unfortunately chose not to doo his and a small dirt nap destroyed his top end. This in fact is the only (first hand!) case I'm aware of that caused catastrophic failure. Under warranty and 3-months later it was returned...with the upgraded doo. Many places you can't legally take a motocross bike, so the KLR becomes the de facto weapon of choice. Plus I'm not going to trailer a non-street legal moto all over the place (Baja, Death Valley, etc.) with limit places to ride when I can enjoy adventure riding all along the way. So yeah, mine has seen severe action. I don't anticipate it lasting as long like the commuter guys. But it would I'm sure if I wasn't so hard on it. Even with good maintenance and care, many pro racers tear-down their machines after each race. I just did an ultra 4k+ mile ride in 9-days including (CO mountains and Mojave and Death Valley) and other than the valve clearance issues I'm not tearing it down. Of course, there are minor repairs mostly from severe vibration but most of these components are over 2 years old (GPS bracket, progressive rear shock/spring). Well, it's good to know you have confidence in the torsion spring holding insitu. I realize the bolt holds the doo but I'm concerned about the process of tightening and loosening it which might allow the spring to somehow reposition out (towards the left of bike) causing it to strike the starter. It's an unfounded concern at this point, so I'd just have to monitor it. Vibration isn't a big concern, but then again I never thought a "secured" the OEM doo could be so bad! So I guess nothing surprises me. I will say I don't expect ever to have a problem with Eagle Mike's doo. All of the doos I've done were sans the torsion option which is why I'm trying to understand any/all issues...which seem in my head so far. I'm very curious about the sprockets myself. Just called dealer...nothing. Still waiting on the cylinder head bolt that installs upside down and this sprocket. I hope this gives me a bit more case clearance. Boy it's tight. The other guy's machine has comfortable clearance, so all that's left would be the chain. The front sprocket was the worst worn, so I was expecting a bigger miracle. Oh well. I adjust my doo at every oil change. Funny with a worn out balancer drive line, most likely I've been dooing it for nothing. A better design might simply be fixing the doo on an eccetric with needle bearings and make it adjustable from the outside with no spring necessary (similar to a fan belt system just tighten a bolt a desired tension. Complete redesign but then again this jingas system needs it. Imagine if EM didn't make a stout doo? You be inspecting and replacing more than riding. The TPI torsion came in a sealed bag. It included a sticker on the package referencing leftcoastkls.com for install instructions. It came with the drill bit. Brian
