So I did Eagle Mike's Torsion Spring "Doo" Upgrade today. I was hoping to see some near cratered damage inside but NOT SO! OK, OK, I agree after working on this beast that the tensioner is not the most robust in the world, but mine was still holding tension after ~ 6500 miles on the bike. Now what it would have done when the balancer chain stretched is probably not so pretty. My thinking is that there a huge variation in the chain wear/slack on the balancer assembly and that is why some people see serious problems before doing the "doo". I'm glad I did it, as now I'm more intimate with the KLR "guts". Also, my balancer chain had so little slack in it, that I had to drill another hole for the torsion spring as there was no way I could get it on the new doohickey at the 7 oclock position. I drilled a 2nd hole at the 6 oclock position and finally threaded the spring around the tensioner shaft! All in all a good wrenching day, even got the FMF "Pipe bomb" header on the bike and will do a video tomorrow. Didn't get around to the front suspension today but another wrenching is in the works.

Cheers,...now back to put that skid plate back on.

Did a Doo for another guy today too. All was good inside, mind you he never adjusted it since new two years and 8000 miles ago.

I'm not sure if the PO ever adjusted this one either, but if you look at the pics, it appears as if it has actually moved to take up slack at some time vs. one single contact point where the hold down bolt is at. All in all, I like looking into things like this. Boy, getting that inner cover off the starter was a bitch! I thought for sure I hadn't taken all the screws out, that O-ring was really holding it in place until I laid down the WD40 and a rubber mallet.

Sorry I missed your tech day, you think a local guy could borrow your doo tools sometime, I have the new Eagle Mikes doo on my shelf. I have been waiting for a warm weekend to get her done.

Sure thing, make a note of my email at [email protected]. I have a couple of drawers on one tool box that are nothing but specialized tools that I've used only once!

Cheers,

John

Got motivated after doing the "doo"...

So again thanks to all for your advise and encouragement. Over the weekend I did the doo, added the FMF "power bomb" header to match the FMF Q4 exhaust, dropped the forks, added the progressive springs and new fluid/seals, and even added an Eagle Mike fork brace. By the time, I got all of that done it was late in the afternoon but I rode down to Boulder to the "pub" and had a late lunch. The bike handles much better with the front end upgrades. I suspect handling on the freeway should be a bit less dodgy with the fork brace. Now all that remains is the high altitude dynojet kit that was back ordered :-( , but should be here tomorrow. I'm on vacation sort of kind of this week so hopefully I'll finish farkling and be ready to ride for the Summer.

John (oh yeah, need to work on the GPZ and the Vrod today as well)

I did the doo on my 87' @ 44,000 miles a few months ago. The original tensioner and spring and tension were in perfect working order before I replaced them with an eagle mikes and torsion spring. I had a hell of a time getting that spring on there though.
