I finally spent some time on this project today.
I made another version to keep the cost as low as possible.
I think 5 profiles and all the holes can be machined in one set up, then the last step would have to be done one at a time unless a jig was made.
But for now, no jig..
I'm getting quotes on the material and the machining.
I hope to have some news fairly soon.
After a few of us verify the design viability then I will let every one know the cost.
Then, I will look at making custom covers and a slightly different design  :-o

By the way, if someone has a CNC and wants to whip up a batch of these to try out, let me know and I'll send you a CAD file  8-)

what do you think about making a coversion of ´88-91 kx 250 and k5 clutchcover conversion... they are very similar ...
the real big deal would be to get one of the factory 2peace-covers and copy it in sandcast...   :-D

I looked at using the 89 kx250 clutch cover.
Unfortunately the kx500 cover is significantly bigger when you compare them side by side.
If you know anyone that has a factory 2 piece cover that would be willing to donate it so we could get it sandcasted let me know  :lol:

The machine shop located across the street from my shop never gave me a quote on these.
So, I have another shop working up a quote.
The owner and I went to college together so maybe I'll get a quote.
I don't plan on selling these at a profit so whatever they cost will but what you pay.
Anybody have any guesses as to the price?

We have a company that provides us with a few different billet parts we include in some of the fuel injection modules we sell at my work.  I will drop them a line and see what they can do for us  :-D

What material do you suggest using for this?

What is the rough dimensions for the piece of billet that will be used?

a 2 peice clutch cover, an over drive 5th gear, a road registered rolling chassis KTM 450 conversion ( black plastics green decals and orange frame) and i think i will call it quits  in the bike tinkering department. I dont think I could get a better bike than that.
