2009 m1000 primary weights questions

[gingerbreadman]

Im getting the sled ready for riding and have the clutches off for a good cleaning. I'm not a well versed sled mechanic but Iv always thought the flyweights should move up and down freely with zero drag, I have the top cover and spring of the primary off and the flyweights all have equal amount of resistance with no binding but they will stay half way, i pulled one bolt out and on either side of the bolt there is a oring, the service manual calls for 11 foot pounds pre load on that bolt so that is where the resistance is coming from. with the nut loose the weight flops back and forth but it is not a locknut and will not stay in place without being torqued, Im assuming the resistance is factored into the spring rate but could someone confirm this for me.

Yes totally normal. They compress the o rings a little. Be sure and loctite the nuts back on.

Any resistance anywhere is lost efficiency. You can do two things. Sand down the outer sides of the o-rings a little. Or tighten the nuts then back off till there is no resistance in the weights movement. I will use Red Loctite on the threads and even put a drop at the backside of the nut for extra insurance. Been doing this since 2006 with no issues whatsoever.

Thats what i thought too, made sense to me for the weights to move freely because like you said its lost efficiency. I called my dealer up and asked him and he said it doesn't matter if they are tight or not, the momentum of the clutch spinning will fling them up no matter what. That doesnt make sense to me at all but just thought i'd throw my 2 bits in since thats what i heard, take it for what its worth i guess.
