My new 2022 600 Touring did the same thing. I did the penny Clutch mod and WOW night and day. The clutch engages right at throttle engagement in High and Low.

Check the forum for the mod it's easy and best 6 cents I've spent so far on the machine.

Just use a gram scale and make sure every one is the same weight. Otherwise the vibration from being out of balance will waste the main bearing...first..then other things. A gram becomes a pound and more very quickly when spun.

Greetings again everyone!
I've resolved the high revving annoyance for my Dad's CForce Touring.

After playing around with different weights I settled on 20 grams.  That dropped the revs a good 800 rpm to 3800 rpm at 10 -12 mph and well out of the 4500 – 5000 rpm fatiguing high rev noise the machine was constantly making.  It is now a pleasure to ride at trail speeds. 

We recently completed a 21-mile ride with about 9 of it in a trail so rough we were often moving along at 4 to 6 mph.  The engine's rpm was clear down around 3000 – 3200 rpm at those speeds and still pulled well.  While my Dad did ride his CFMOTO about 75% of the time, I took a turn during a part that rough section.  When I was faced with a steep section at those speeds I did stop and select Low Range.  That raised the engine revs 500 rpm putting it back where it would have been spinning at 10 mph.  The CForce performed wonderfully and was a total pleasure to ride.  At no time did either of us detect any belt slippage.

I performed some acceleration runs while doing evaluation of that weight set and the engine spun up to 5000+ rpm right away and would pull revs in between depending on the load and speed.

Note the primary drive clutch spring is a 0951-1015 which equates to a preload of 200 Newtons and a compressed load of 900 N.  That is right in the middle of the chart.  I don't know if that's an original specification but it is the spring in my Dad's used CFMOTO.  Oh, and the weights that were in the clutch when I started were 11 grams each.

I'd say this is certainly not the solution for everyone, but if you're riding at trail speeds in your CForce Touring and find the high revving operation tiring and annoying, give this primary drive clutch tuning spring & weight combination a try.

Congrats. Good info.

Look at Real Talk Powersports videos on YT. He and Main Street Cycle have done a ton of work modifying the clutches to better suit different applications and riding styles.

The cforce 600 parts catalogue has 2 different weight options. 10g (stock) and 16g. Maybe the 16gram option is for cruising and people who wants a more tame machine

The heavier ones would certainly bring the RPMs down...something a lot of people want. 

Put the 16g weights on my 600 and the take off is much smoother and at lower rpms.
Also the cruising rpms dropped from around 5500 rpms to 4800rpms, wich makes the quad quieter and smoother.

Great to know 5 or 6 grams will make that kind of difference. Many people are looking for that..even with the larger engines. Makes a good starting point.
