The 1 I have is a direct replacement for a 04-07 blade. Though I know they fit the SP1-2. I tried fitting it to the SP1, but I'm pretty sure I need to add an extra spacer in to let it push the push rod further to activate the clutch. Really well made and you can feel how well it works at the lever.
It was not meant to fit the SP, but from the RC51 forum I learnt that it would fit straight on and it did. As said all that is needed is for a spacer to be made so that it actuates the clutch properly. Currently it Only pushes the plates out half way.
I found that the lever would feel slack till around half way in travel and then you would feel it push the rod. Which makes me think that there is a need for an extra packer in there. (You already get 1 with the kit).
Ah. So you have already worked out what's needed then u sneaky git That would make for a brilliant feel at the lever.
