750 clutch sprocket weight reduction

[dja981]

Who sells these clutch drum holes and how many would I need? Oh and what size should I order?

I haven't got much money now. Can you give me a price for half a hole?

Much appreciated, I know how important the weight issues are!

Price is dependant on hole type, half round hole is dearer than half a equilateral rectangle hole. Oddly, we don't do square holes ................... what's it to be then?

An equilaterally triangular orifice, I was told them is real good

Tappered I presume?

Do Mirages require invisible holes?

No, just holes on the outside only.
