Alrighty then!
Pulled everything out of the box Adam sent me. Everything looked good just like the videos.
Okay to the Install. Had a tuff time using the clutch removal tool to get the Inner half of the primary off. Finally after using a torch to heat it up then using some axle grease on the threads of the removal tool. Viola! With a Bang she popped off. Used Electric Torque wrench to take it off.
Now how can I explain this. Trying to compress that secondary spring and slide the two halves of the clutch onto the shaft is miserably difficult, when you dont know what you are doing. The position of the motor in the Commander there doesnt allow for alot of manuver room. Finally, I stepped into the seat area, bent at the knees hanging onto the roll cage above and used my Heel to push in on the hub of the clutch. It gets better, after I had it pushed in all the way my buddy used a 3 foot crowbar to wedge in there so it didnt pop back out which freed me up to screw the bolt in. A video would have been priceless. Laurel and Hardy got nothin on us. What could now be a 20 minute job ended up at two hours.
Now for the good part. One, upon start up everything looked and Sounded great. Even with the exposed CVT it was much more quiet and just better sounding.
I put just the seat in and left all the panels out including the clutch cover. Two, drove it up the block to my house and I have to tell you, the herky-jerky start, off idle, is now GONE. Yes thats right folks, no more on-off lightening starts either in reverse or drive. You can now look good cruising out of vendor row, kekek. I noticed that it doesnt hook up right at 2000 rpms as in stock form, its more like 2200-2300 but its smooth as silk.
Didnt get it on because I was in a hurry to load up and get it down to have my Exhuast and chip installed. Gonna have to take this baby out real soon now.
One last bit of good news. I dont know why but with this clutch the CLANK sound when putting it in gear is GONE as well. No more Clank, awesome.

The Power block is a similar clutch and I just made a tool out of a piece of 1" square Billet aluminum that slipped over the edge of both halfs. You would run a bolt thru the center with large washers then tighten the nut untill the clutch was compressed enough to install the tool. Then remove the bolt and spring tension holds the tool in place. Slip it on the shaft and install the bolt. The clutch halfs will then compress and the tool will drop off.

Nice idea Steve...got a measurement between the 2 shoulders that hook the sheave halves?......Lance

Because the clutch withes will not be the same you will need to measure the one you want to make the tool for. Then add about a 1/4" to the opening of the tool.

Gotcha.....thanx,,,,,Lance

Just a note: You can also use the tool on the clutch when you remove it for like rebuilding the motor etc. That way it will stay together on the bench and be ready to reinstall.

this clutch setup is not the same as the kawasaki and suzuki styled setups. you actually have to compress the spring IN the bike. the spring is not incased in the clutch. the clutch is its own assembly, and the spring sits behind the secondary clutch. you have to push against it in order to get the clutch on. i can say it is not a one person job. its more like a 2 person job, one to push the clutch on, and one to start the bolt.

i will try and have a video up of the complete disassembly and installation within a day or two for everyone to see. i have an owner coming in thursday or friday and i am dong a full install in house and will get the videos of everything and post them

 

[Odyknuck]

Thats Interesting. It certainly appears to look and work like a power block clutch. I am looking foward to seeing this spring behind the clutch concept.

How much does the new CV tech clutch cost ( complete with all needed for the swap ) ? Thanks

 

[Xelvic]

Great to hear Razorback. Did you have to install the shim? Also, did you request to have it engage at 2200 rpm? I would like mine to engage around 1800rpm if that's possible. I do a lot of slow technical rocky trails.

Hi Xelvic,
No shim for me... its aligned perfectly. I just followed Airdam instructions.
One question I had was that Adam had installed a kind of a flywheel plate on the inner half of the primary. He explained to me that becuase of the odd firing order of the 80 degree twin, there is a lull in the power sequence that the crank is spinning on momentum. He said i could take it off but i left it on and Im very happy with the result. I really am excited to get out and do some REAL duning with this puppy now.
Adam has some videos comming in a day or two about complete in shop installation of his CVTech Clutch. Im sure he will explain everything in detail.

You can kind of feel the clutch grabbing hold at 2krpm but it really moves the machine out at 2.2k rpm... I really like the softer launch....with a light foot.
Im sure it will hook up and spinn the tires with some real throttle. It does make it easier to put in the trailer tho.
Xelvic if you are on the fence about it, I can only give you the idea that it is better at this time. I will give a real commander test with pics next comming trip.

this clutch is very similar to the powerbloc you are thinking about but the secondary clutch is the one that we are having troubles getting on. the primary is one assembly and just simply slides right on the crankshaft. the secondary is the tough guy.

 

[Odyknuck]

Ok, I misunderstood.

hint..hint..LBR I think you need to buy me a new clutch for Christmas....
