dry clutch conversion kit

#1 Post by jan buijk » Mon Apr 23, 2018 11:39 am

Hey everybody
I'm working on a completely new clutch cover to be milled
i have alraedy a welded dry clutch version , bud i want it better in one milled part
and also to mill a dry coupling lid here, with a ducati size, in which a complete ducati - yamaha coppeling modification fits in, not an extension of the output shaft, but use the existing shaft, to disassemble the entire block unnecessarily ,I want to make 3 different versions

A: an entire copy of an original lid, so 100% original
B: a dry clutch version, with kickstart possibility
C: a dry clutch version , without kickstart possibility
C: a complete conversion kit
with a ducati modificati coupling type
in consultation with the buyer
my question is also whether this is interested, and which version?
have everything already let 3D scan and are now working to achieve e.e.a. with drawing
please send an e-mail to jjbuijk@hotmail.nl if you are interested

Hi, Jan. :smt006

I'm interested to see what you're up to. You've got my email address. Send me some pics.

Have to be honest, though. Been waiting years for sergio90 to finish his dry clutch kit.

I'd be interested in "B". The first one or the second one. :)

I'd prefer a kit that only included the custom made parts. I have a Ducati clutch already. I started to design my own dry clutch years ago. Never had the time to actually make it though. The price would have to be reasonable for me though.

It is possible to remove the steel splined insert from the stock aluminium clutch hub and shrink fit / weld it into a Ducati hub.
(I used a Ducati hub with a cush drive, which happened to be steel).
That's what I did anyway..... :cool:

First, I think you have a typo in your original post. You list options A, B, C, and B again.

My lunch break is about over so I'll get booted off the internet. I'll get back to your question tomorrow.

Most people that do this mod tend to copy the design of other bikes that came with a dry clutch. Not a bad direction, but I think it requires more work to existing parts or replacments.

I was going to take a different approach. I found my incomplete scetches from about 8 years ago. I intended to replace the RZ clutch basket with a custom part that would be driven with the stock cush drive springs. The cover seal would ride on this part and the outer clutch basket would bolt to it.

Next I would make a hub with internal splines to mount on the shaft. The internal clutch basket would have to be modified to mount to the hub.

I never completed my design so I'm not positive that it's possible to retain the stock input shaft. That was the primary goal of taking this approach.

Hello Jan,
you should plan to offer a version without waterpump opening. Nowadays people move to electric pumps if they build such projects
