Beware the Eagle Mike Doohicky mod spring

Just checked the 6th KLR to have had the Eagle Mike Doohicky upgrade...the coil spring was broken...as well... that makes it 6 out of 6, all fitted by a reputable dealer.
Also then found that the roller bearing inside the idler/tensioner sprocket had collapsed???? a very strange thing, unfortunately only able to account for 9 of the missing 11 roller pins after fishing around with a magnet, draining the oil and removing the clutch side casing as well. (had the bike on its side to do the doo without draining oil, easier to work on...hmmmmm).

All that I am putting out there is that all of us thinking all is well inside the engine after we spent money and time doing the Doo, Take the time to have it checked out....PLEASE.

If you are in Cape Town, South Africa...I am happy to have a Doo Tech day at my house....just get in touch with me through the Forum and we can set something up....it takes all of 30 minutes.....total.

So your saying that the actual Eagle Mike springs are breaking? Have you contacted Eagle Mike about this? I'm sure he'd like to know! I have the EM Doohickey and torsion spring in my closet waiting to be installed but now you have me wondering...

Please contact Eaglemike and let him know about this.

Either the parts are counterfit or the dealer that installed the parts did not install the spring correctly. Whatever it is Mike needs to know.

I installed mine right away and have had no issues. That being said, heat treating springs is tricky business and it's not impossible that one of his springs was improperly heat treated. Please contact Mike directly so he can sort things out with his spring vendor. He may need to recall some kits. Are you suggesting you've installed 6 kits and have had six failures?

Well, I own three KLR s 05, 06 and an 07 all had the doo done by a reputable dealer, got the stickers and all. took my 06 motor apart for gear problems and discovered the doo spring broken, this lead to opening the other two, all broken, which lead to opening three friends KLR s, these were also broken, one was fitted by the same reputable dealer, the other two fitted by unknown mechanics...just seems a little too coincidental to me that of the six I have checked, all were broken in a similar way, reputable dealer just shakes his head and says...have not had any comebacks..... I emailed Eagle Mike but got no reply...

Thanks to those that forwarded this link.

I rec'd an email this morning from a person I think is the same as the OP of this thread. I rec'd the email at 11:08, and responded at 11:42, so only 34 minutes passed. So some of the above is misleading..............

I have not had a total of 6 springs break before that I know - this is from the total number produced. This leads me to think there might be an installation issue. Either way, I want to support all the products I sell. There could have been a heat treat issue with the springs, but this cannot be said with certainty. The springs are produced in the US. I do visually examine every spring before it's packaged.

I've said this before, but I think it bears repeating. The torsion spring is a far better setup. The extension type setup is constantly cycling a minute amount while the engine is running. This will contribute to spring fatigue. Even engine revolution the spring cycles 18 times. That's the number of times a link plate passes of a sprocket tooth per revolution. There is some slop in the spring lever to shaft fit and there is also a bit of play in the adjustment lever to shaft fit - although much less in mine than the factory parts.

If the OP wishes, I will send him 6 torsion springs as replacements.

I don't know for certain (at this point) if the original spring were all mine. It doesn't matter - If the op will send me name and address I will ship these USPS International Priority mail, and will post the tracking number here.

I think too many people forget to reset the spring tension screw periodically. This applies for the EM spring and stock spring. It's just good maintenance.
