Ok,, That’s to the point! Thanks,, But, can you explain what is happening in the bike if the Doo is not replaced?Tell your friend too ask the dealer that shot it down to write out a legal guarantee that the doohickey and spring in his bike will never fail, and that all resulting damage will be paid by the dealer, in full.
When the dealer refuses, spend the $40 and address the issue before it causes catostrophic failure of your engine..
$40 is pretty cheap Peace of Mind, if you ask me.. I've seen 4 broken Doos or springs removed from KLR 650 motorcycles. 4 were broken out of 10... 40% failure.. $40 fix.. Seems simple to me, but I did mine 3 years ago and haven't had to worry about it since. $40 well spent..
Thanks for simplifying it. I agree and will pass this info on to my friend with the 07. We get together often to ride and I’d hate to be stranded somewhere with him when his goes!If the spring breaks (happens a lot) when you loosen the adjuster bolt you're allowing the chain to go very slack.. This causes grinding to the inside of the cases, or worse, allowing the chain to jump teeth.
If the adjuster breaks, you have loose parts floating around in your bike, plus your chain will have zero tension, causing the issue above..
The adjuster was updated on the Generation 2 bikes, but from what I've been gathering, the springs have no tension when new, so it doesn't matter how often you loosen the adjuster, it's not doing anything as far as adding tension to the chain, which is the whole point of the unit in the first place. Chain gets loose with and wear, and you're back to the first paragraph..
Or, a couple hours and $40 and you don't have to ever worry about it again.. Eh.. Seems like an easy choice..
I wouldn't recommend it if I hadn't seen so many broken units and heard about dozens more..
A little late on the response here, but as KL600 info can be hard to find, when i saw this post, I registered on the forums just to post an answer.Anyone know if the doohickey is a common part to an older 85 KLR 600?
I'm thinking it may be a good thing to be proactive and install it.
Hi and Welcome CactusJack!Hi guys, newby here. I would think one of the first signs of the tension spring going bad is timing chain noise or slap inside the engine. Tpyically what is the springs life span on average? I've had a Honda that the chain tensioner went bad and you could tell by the sound. The Honda set up was different but if ignored it could cause some damage.
