The one on the left is for a bucci slipper ain't it?? just had this in reverse, fitted a Bucci clutch and my JHP plate won't fit, it needs to be like the plate on the left. Do you want to sell it??
JHP one will need teeth machining out, I'll up a photo later this afternoon but its the black one at the top of this pic, as you can see the plate contact surface is flush not lower than the spring cups.
Graham. Ive got a full ATcorsa slipper and i think the plate is the same as mine. Why don't you pop round and have a look . I've got to give it a partial strip for a clean up, and check the dished spring plate.
