I have a new M8, I have not had it out yet. I have herd through the grape vine that there is a clunk either on de cel or after de cel when accelerating. Appearently something to do with the electronic reverse and the way the notch is cut in the helix. Has anyone noticed this?
2009 M8/M10 Clunk
- Thread starter xray
- Start date
Is it the way way the helix is cut for the electronic reverse, or is it caused by something else?
Most likely the helix due to the reverse. Have heard that sound for years when I used to ride Poos with reverse. Haven't had a chance to ride my new M8 Camo SnoPro yet but I expect to hear the clunk you are talking about.
Any and all sleds with R.E.R will make that noise, It is the helix sliding into the reverse notch. There will be no recall or way to fix it, that is the nature of the beast.
2009 m8 sno pro same here , good to no it is not just mine
that sound is very loud (clunk)

my 08 m8 makes a awful clunk when coming out of reverse. make sure the rpms are at idle before going into or coming out of reverse. the higher the rpms when pressing the reverse button the worse the clunk, my dealer said if the rpms are high when enguaging reverse it can do damage to the gears
The noise from the 2009 is from the clutch (helix) not the DDrive
I beg to differ. My 07 doo didn't make a noise, nor do my riding buddys dragons or xp's. Haven't had a chance to try my m8 though.

My 03 Escape would do it too
On the 09, look at the helix, I don't know how it could NOT make a noise unless you're very gentle with the throttle as it goes from the ramp side to the notch side. Not too fond of this new helix, but I don't see how you avoid it.
On the 07-08, Mine did that too, just gotta keep the R's down. There should be a limiter that keeps It from switching above 2500rpm I believe it was?

This may be a dumb question. Could you put a standard helix in?
Then you wouldn't have that gap between the rollers and the notched side of the helix. I dont see the secondary opening up that easily due to everything is spinning in the opposite direction as the helix ramp. But as I say this might be a dumb idea from a newbie to the sled world.
Thanks for the heads up about the clunk though.

Sure you could, your reverse wouldn't work right or at all though.
isn't this a no-brainer?
I would think so, isn't it obvious that you should be idling before you switch into reverse on any system?
Maybe I am reading this wrong..... But wasnt the question if anyone had a clunk while accelerating or decelerating? Not when engaging/disengaging reverse? And yeah if your motor is running above 3000 rpm the reverse will NOT engage even if you do push the button
Mine clunks too!
But I don't believe its the secondary. I took mine off and turned the shaft the secondary rides on. It has a good amount of play. It clunks when you twist it back and forth.
So I believe the clunk is from the diamond drive itself.
