2016 Cforce 400s clutching questions
« on: April 27, 2017, 07:50:56 am »
Good morning,

I'm considering installing some larger mud tires on my new 400s and another forum member brought to my attention some adjustments I may need to make to my clutch.
The stock wheel size is 24" and I was considering a 26" or larger tire.
I guess what I'm looking for is info on how this will affect my clutch and what adjustments, changes, modifications I may need to make. This is my first rodeo with a CVTech clutch. It's also my first CFMoto machine.
Thank you

26 will be the MAX you can put on without spacers , Fronts will hit. 25 is about right for that machine.
As for clutching, 10g weights and secondary to A1 , this should have you set up.
If you don't want to change weight the secondary to C1.
B2 is overboard for that system.

If it has Pistons or Tits you will encounter problems.

I'm curious as to what these changes will do, would anyone mind explaining what I'll be doing?
Also, where can I find more info, manuals and guides for this kind of work?
Should I have my dealer make these adjustments? I'd rather do them myself but considering this came with a 3 year warranty I'd hate to void it in one swoop.
Thanks

There are some good YouTube videos out there. Here is a link for one on the secondary.

One on the primary. This is a canal, but the concept is the same.

Keep us posted on this. There is not much info info on the cvtech primary tuning, at least for cfmoto.

Absolutely. I've watched several youtube videos on CanAm CVtech clutches in the past few days.
This doesn't look like a difficult procedure at all. I guess I won't know until I crack open the casing on the CFMoto but I've got almost enough courage to do this myself soon.

For the weighting of the primary, it seems people are using 5/16 washers which are about 1.7g each. If I place 2 washers under 3 weights it will be about 10g. Should I place 1 washer under all 6 weights instead? That seems the logical route for the same weight. Keep in mind I haven't taken it apart yet, I'm going completely by what I've seen and read online here and there.


I found these videos helpful -





Thanks all

I wouldn't stack weights. It will go ok for you. Just give yourself time in case you get stuck. The only thing I had issues with was the key in the secondary lining up. Just takes patience.

The primary clutch doesn't need more weights.
Less if anything

I'm not sure what weights are in there now, but yes you will want less weight and make sure it stays balanced. Meaning all the same or evenly distributed throughout. Less will move the cvt working rpm up so your closer to the max horsepower output. Just keep in mind that the rotax puts out more power than yours.

I misunderstood the weighting @wheels, my apologies.

I think I understand now.

Here are the new mudders mounted.

Thanks for the continued help and I'll post what I decide to do.

Its scheduled to go into the shop on the 15th. I'm getting the warrenty kit for the Airbox taken care of since I found oil in there and they will have to fix or replace the whole thing anyway it looks like.
While it's in there I'm going to have them make the adjustments suggested earlier in the thread.
Since installing the larger heavier tires I definitely noticed a difference in engagement that bothers me enough to do something about it. I'll have news soon.
