Monster 796 clutch conversion?

[bikepilot]

Wet clutches work really nicely, embrace progress 

[Punx Clever]

I like my dry clutch.  I can open it up and let the hampster that turns the motor breathe a little easier.

But in all seriousness, I much prefer the feel of my dry clutch to wet clutches i've ridden.

Small case wet clutch to dry clutch conversions have been done, but there is no info out there and most will give you a crazy high price quote just to avoid doing it.  Here are some photos of the difference between the small case & large case transmission input shafts.  They are from a 695 & a 749 but I do not think it has changed any on the latter models.


This is the wet clutch small case, notice the way the threads are set up in the splines of the transmission input shaft.



This is the dry clutch large case, the input is about 5mm longer then the input on the small case engine.  The shaft also necks down to the threads.

The splines are the same on both input shafts so the cluch assembly can physicaly be installed.  The nut that holds the clutch basket will be the main issue.

I stand by the notion that every Duc should have two options:  First is a red frame and second a dry clutch, if you so desire.

thanks for the well taken photos

Ahhrrr... i see many cases of "the dry clutch envy" coming down the pipeline once the mod bug hits these new Monster owners.
There is definitely a market there for a company to put together some sort of a conversion kit.

It seems both wet and dry clutches have advantages/disadvantages...

But the main reason people seem to like it is for 1. looks, and 2. the sound.

I have seen some sport classics that have a clear cover to show off the clutch, yet retain the wet clutch.... and from what I have read, it seems to be much cheaper than a full on conversion...

I have seen one new monster with this as well..

This seems like a pretty sweet, unique, and cheaper option for us wet clutch guys to get the "look" of the open...

Might be a good project!

Wow... none of the new Monsters have dry clutch. This is really sad.
Looking at the rest of the Ducati line up... i see where this is going  All part of the "green agenda" bs!

ummm, 1100.

as you noted above the shaft is shorter on the wet clutch thus the nut that must be put on is not the same that comes with the 848 conversion kit and has to be custom made, that is what i heard from my local dealer that put the conversion kit on an old 620 monster that everything bolts up fine but the problem is the nut has be be custom made, so its something you ahve to have done by a machine shop, so in all it ends up costing you something like 2k dollars for the conversion since the dry clutch conversion kit 848 is around 1500$ to start and a few hours labor and the custom nut make up the difference.

ummm, 1100.

The new EVO is a wet clutch. There is no current Monster with a dry clutch

THe 848 kit costs 1500 because it comes with 1 Magnesium side cover and 1 EVR slipper clutch.
A simple kit would cost a LOT less if they use a standard cover and clutch.
Telling you, if a dealer were to setup this kit, they would make a TON of money.

Wanted to dig this topic up again in case anyone had anything new to share, the new gen monsters are getting much more common and I know theres still interest in the mod.

I talked to my local dealer and he is sure the 848 kit will fit right up, in fact he said he would be willing to bet money on it.  (of course people have already determined the customization required)  I think I will try and wrestle a deal out of him, I buy the kit, he figures out how to make it work using my bike as a lab rat...and he gets to keep the bragging rights that his dealer does dry clutch conversions on new monsters. 

Ideally I would like to pay for parts (the kit and machinging of custom parts) and have him donate labor...
keep your fingers crossed for me.

Also when I talked to him about it, his high points for the dry clutch were as follows: 
1) no clutch material contaminating the oil.
2) the wet clutch monsters use a drive gear assembly with a spring preload device...its designed to reduce gear noise...but it actually has a slight parasitic power loss...(proabaly in the neighborhood of a HP or two...but with my 135#...thats a decent amount...)
3) of course the customization options and incredible sound. 


Ill keep yall updated!

 if he develops a production kit with those custom parts. PLEASE share.

The good news is EVR will start producing a true slipper clutch for the small case motors this spring!

[freeclimbmtb]

honestly, I hope your right...because if I rope him into a deal...then I'll have a one off! 

Now that I own the bike im almost toying with trading up again for an 1100s...and get my damn adjustable forks and dry clutch. 

dealer is smoking dope according to all my research to include talking to EVR engineer.
The small case motors are different in many ways.
It will require a lot of custom work which is why I haven't started yet. BUT if he develops a production kit with those custom parts. PLEASE share.

It's called a dual mass primary gear and it has been responsible for a 'few' heavy engine repairs.
Older small Monster's one piece gears can be fitted to avoid this issue, but it's making a really loud high pitch noise.
