Bronze clutch plates

An elderly Dominator 99 I purchased has been fitted with bronze clutch plated bearing on steel plates. The clutch slips with the engine loaded, before full throttle.
Why anyone would fit bronze plates to a 65 year old bike is beyond me.
Anyway, the clutch springs are screwed in quite tight - could go a little more.
My question is - should bronze plates be paired with steel plates, or should both pairs be bronze?
Does bronze/steel have a different coefficient of friction to fibre/steel?

Should be ".....bronze clutch plates bearing on steel......"

Whatever clutch and plate combination you have does not seem correct. Not unusual with the Domi's.

What oil are you using in the primary?
I have a commando with the bronze/steel plates.
I use ATF which helped to limit the slip problem.
i also machined off half the pressure area to increase the 'stiletto heel' effect.
might be worth trying.
otherwise back to standard plates.

Hi Tony,
What do you mean 'stiletto heel'?
It's a Dominator, not a Commando.
I think it's ATF, but I'll check.

Hi Richard,
I know it is a dominator but you have commando type clutch plates, I.e. phosphor bronze, and yes they should be matched with steel.
The stiletto heel effect is you get a lot more point pressure under a stiletto heel than a flat shoes.
Look at RGM part number 050008 for what they call the high torque plates.
may be worth trying to modify yours.
