Just geared down from the stock 57/63 gears on my M8 to 53/67. With 14% more torque will I need to add or remove weight from my primary clutch?
More or Less Primary Weight for 53/67 Gears on M8
- Thread starter SaberKitty
- Start date
In theory you will need to pull some weight out. Not first hand info, im just waiting for my 54/66's to come, but thats what i've been reading. That thing should have some low end grunt!

Oh boy,
I just installed the 55/65 in mine and am a little confused now.
BDX said I wouldn't need to re-clutch, however, I'm down on my trackspeed in a deep hillclimb.
I'm taching over 100 rpm higher than I was, so losing weight would be a no no.
My throttle response is still snappy, but the track isn't hooking up and pulling like it used to.
HELP!!!!!!!!!

I'm going through the same thing, with gearing down the secondary has to shift out further, but with the combination of stiff springs and shallow helixes it just gets to hard to overcome.
I even have a cpc torsional kit but with the stiff orange spring it seems to be the same story, gonna try it with next to no tension to start and see how that goes, but I will bring the trusty red and white just incase.

I have to take what kelsey says with a grain of salt as I feel that he's only half right more times than not.
Anyway, yes my track speed is lower now on a deep powder climb. My R's are up, and I will load the adjustables with more weight.
We got 7' of fresh this last week, and had this not been the first day of a full blown season, I'd have the stock gears back in tonight. Snow again tues, so I'm riding till then.

If your track speed is down I'd say put the stock gears back in. You had the power to pull them.
I'm going to try the same thing too.
what rpm are you hitting, I would say throw in a 2* steeper helix, before the gears and track where loading the motor now its turning easier and a steeper helix should give the primary and motor more feedback. These AC motors seem to like being loaded.
Honestly 53/67 is way to low i think, it will put your clutches into over drive and reduce belt sheeve contact in the secondary and start slipping. has anyone checked how hot the clutches are, are they hotter than before.

This season I've really enjoyed the 53/67 gears for boondocking through the trees with less belt slip, more torque/power and throttle response.
The right gears all depend on how/where you ride - Everything is a comprise; you can't have it all. Track speed on a hillclimb is not something I'm concerned with as I don't do it anymore after a friend was in an avalanche.
With the 53/67s, I'm running 78.3g of weight @ 76-7700 rpm. It's a torque monster tractor.

I changed from stock (2007) 57/63 to 55/65 (2010 stock) I lost track speed on the long climbs, however the sled is way more fun to ride 80% of the time. I think with some clutching I could get some back. I did drop 2 grams off the primary and unload the secondary spring to softest position. My clutches are not near as hot as they were with the stock gears.
