Okay, I've got all my parts on order, my GDU has been rebuilt and I should be starting the reassembly next week. 

As I was getting organized on my workbench, I moved my clutch assembly off the one side but as I grabbed it I noticed the last disc was actually cracked. I have absolutely no idea how this happened as when I took it out I brought it over to where it's at until I moved it getting organized.

I don't particularly want to buy a whole new clutch as this one was working very well. I have never owned a motorcycle before so I don't have enough knowledge if I can replace just one disc? It is the very outside disc as you can see in the picture at approximately the 5:00 position. 

Can I replace just one?

@meatman the technical control seal in your picture has been tampered with. The wire has been fed through the (wrong) closed end.

Regarding your clutch question, I would advise replacing the plates as a pack (1 broke, why risk it). A cost effective OEM kit is available but the springs are not to Radical spec.

Looking at your Gen 1 gearbox, I hope you have a service manual on hand for plate and circlip direction (orientation to load) torque specs etc. 

Best of luck with your project, Rich

Almost ready to drop the engine and GDU backing, something I noticed during the dismantling process is that I was missing a few bolts (see pictures)

 

I wonder where I would be able to get some of these? Anybody have any spares? 🙂

@meatman 

Your clutch slave cylinder mounts through those bolt holes.

Noted that there is no output shaft seal there (plus spacer)? It gets clamped between the crankcases so needs to go in before the cases go together.

@rlm-dan The seal is installed now and thanks for the tip. I suppose I would have found that out eventually eh!

Hopefully I get a quick response tonight on this question...

 

I am installing the clutch and notice the spring washer and the spring washer seat were not installed when I dismantled it. As far as I can discern they are used to lessen clutch chatter. 

 

I don't care about chatter and was wondering if it's okay to not use them? Is this deleted in a radical setup normally anyways?

Early Busa's (99-01) didn't have these washers fitted as standard but everything else did. Radical leave them in everything and fit them to engines without them to assist.

Having said that you should be fine without them and the clutch will work fine without them.

If you suffer any problems with juddering/grabbing and general clutch behaviour then they would be the first thing I would look to fit.

Anybody have suggestions on how to tighten the sprocket (output shaft) nut?

 

I know it's supposed to be 105 ft/lbs but the shaft spins even in gear.
