The wet clutch delete kit remove about 7 lbs of rotation mass

Meaningless in the overall driveline, wheels, tires, driveshafts gears etc. Then how close is the weight to the centerline?
I'll disagree with this statement. Losing weight in the rotating mass is never meaningless. Especially if some of that weight is at the crank

What are you talking about !
The engine braking is as strong as stock .  That is an indication of a trouble with you installation...
Please do the correctly before posting wrong information.



Interesting, I just checked the clutch for a one sprag ......guess what it does "not" have one. So you will have to educate me how the engine brake works? You do know Can Am uses a a one way sprag for engine brake?

Bad choice of words, I should have said you would not notice the difference in the overall package.

Second, I would argue the seven pound loss. Just weighed the kit by it's self.......11lbs, it's heavy.

Vforcejohn, one of the most recognized names in the V-twin performance game's "claim to fame" is his Stage 1-3 machining mods to primary clutches where he takes off just ounces of weight making vast improvements in power and acceleration. He also uses different sheive angles,springs and flyweights to extract even more performance but it's that weight reduction first that makes the noticeable difference...and that's just ounces off the end of the crankshaft. So, if this kit actually takes "pounds", even ounces off the end of the crank, it should be a "very noticeable" engine performance gain.

We all know about rotational mass and weight and how it robs power and acceleration when we add larger or even just heavier tires.

For me its not even a question since I have absolutely found no downsides with this kit, only major gain.

- stronger power
- free reving engine
- no more rattling sound (the only   sound is now the exhaust !)
- you can use any oil
- no oil contamination by the clutch
- no delay between gas pedal and wheels.

NMK, if you want to cover the freight & go thru the process to install this killer clutch I will send it you for an independent evaluation.

I find it highly unlucky you will find it's 7 lbs lighter & if engine braking is important we need an explanation how it works.....because it doesn't.

I'm very confident you will find your current set up with the little tuning you've done is better.

Here is directly from CF Moto Canada website...look at the 3rd statement...


R800 Stage 1 Kit
Once the R800 Stage 1 kit is installed, you will immediately feel the acceleration effect.

The clutch kit will also provide:
Greater top speed!
Superior acceleration
Better compression effect (deceleration)

Well this thread grew legs! I see now where the massive performance gains claimed for the elimination of the wet clutch for the dry, come from. A bit of comparing apples with oranges I think.
Quote
...When dialed properly, the engine jump to 7200 rpm instantly and stay there to the top speed where it climb to the rev limiter at 7750 rpm. ...

There appear to have been extensive hop-ups and changes done to this machine besides the eliminating of the wet clutch, and performance with all these modifications are being compared to performance of a stock CF Moto!
Not a particularly fair comparison, but as always the compromises needed for the straight line performance increases, must be paid.

Speaking of the CVT alone, if the machine instantly jumps to near rev limiter RPMs when throttled up then you have a drag racing machine, and one that would not be much fun for recreational riding at least by my reckoning. I like to go places and see things, and overcome the odd technical challenge.

If significant weight has been removed from the crank line and it's become a belt slammer with a high engagement RPM already then I can see that on pinning it at a standstill, the crankshaft will whirl up to valve float RPM before the primary closes on the poor belt, providing more snatch at the start and maybe even a wheelie if its on pavement. It also makes the machine even less tractable. How is it at moving ahead just six inches while loading? :)

If that's what's fun though, there it is. Not my cup of tea but if everyone wanted the same thing, how boring would that be?  Peace out.

Your are completely wrong on that. The rpm jumps to 7200 because I floor it to the metal. If I move the gas pedal normally the sxs move very smoothly. I find the clutch kit smoother than the stock one because no more clunking engagement...
The engagement is normally at the same rpm as stock. Mine is now a little higher because I want it.

I don’t have extensive hop up, it’s the stage 3 directly from CF Moto.
-wet clutch delete kit
-Power Commander
-Slip on with quiet baffle.

And I have seen absolutely NO WEAR on my belt in the last 1700 km.  It’s not a belt slammer !

CTDLS have many symptoms of a bad installation...
No performance gain
Belt failure
Clutch not aligned
No engine braking...

It’s not hard to see that something is wrong with the installation or with a defective part in the kit !!!

Very tempting. Wonder what it would cost to ship it to 87109 from there. For me...and my needs, I have been happy enough with the wet clutch setup and my tuning but the one thing that still gets me is the oil contamination from the clutch...and all that damn noise....lol.  With the deflection set right and backshifting working correctly, it should.. have engine braking down to about 9mph where the primary lets-go of the belt. That's really not slow enough for me in some mountain situations but in low range that be take it down to about 4. That may be OK.

ctdls, you have a lot of money tied up in this. I really think you can get most of it back out. I'm sure there are people here or on FB that would gladly buy it from you.

It's the stage whatever kit directly from CFMOTO, I called BS on all claims...it does not work as advertised.

I've asked a few questions in this thread with no answers, what does that tell us?

Certainly there was an alignment issue because of no mention in the install instructions. When I called the shims & alignment tool were sent out. The alignment issue was corrected.

I could have put it on the dyno & possibly improved the fuel map, by then I was so pissed off & the final nail in the coffin was the deleted engine brake.

No belt issue's because it wasn't installed long enough.

BTW it is loud.

What questions are not anwser?

The kit is a CVTECH TRAILBLOCK primary clutch that is sold for all kind of ATV all around the world .
People that have atv without wet clutch paid for this clutch just for the benifit of basic design, reliability and performance gain...

An NO, the engine braking are not deleted , it is better than stock .
Just this have proved that something is not correct with your installation. You also tell it’s loud... this clutch make NO noise.

As soon as I can I will post others videos.

Anyway, continue with your set up if you like it. On the 2 ZForce 800 that I have install this kit the results are the same. Way more responsive, a lot quieter, smoother, and no more black mark on the poulie and no dust.

How does the engine brake work with this dry clutch? There is no one way clutch.

What could be wrong with the installation, it's very straight forward?

Meant the exhaust replacement muffler in this kit is loud.

I don't like the current wet setup form a calibration perspective, when our season returns I will get back to it.
