I don't think there is sufficient clearance in the Honda clutch to fit it.
Hi Hugo,
It is possible to fit a needle roller pusher on the Conways Honda clutch, as we did it on my late fathers outfit
There is not a lot of room, and you have to do a little work on the pressure plate..
If I get chance I will draw something up over the winter, as I need to do the same mod on mine.
