Not sure if it causes plates to hold oil & stick/grab? (when you pull in the clutch & move the trike). Not sure -since on the manual clutches the plates do not come with this from the factory- Are they not a problem?-(for those who have used them)

I called Barnett. They say that that they DO dimple theirs and that the dimples are there to allow oil in to cool the plates. They also said that providing the correct oil is used that the presence of it in the dimples will not hurt performance.

yes my maico was not 14.1 like yours so that added a bit more power but my cyl cylinder kick back was still from an eng that displaced 150 cc more than a single kawi cyl.

ok cool. yeah you got a tech guy, i mentioned it was also there to cool the clutch in my previous post. there is a bit more to it than that though. they do have plates with no dimples though. the high horse race guys use no dimple plates because the dimples reduce contact area which reduces holding power, simple fact.

think about this, a dimple is the same as a hole with respect to surface area. imagine if one was to drill 50 3/8" holes in every single metal in a clutch. there would be very little surface/contact area. the clutch would slip more than a greased pig on ice.

Below is a link to a page with 20 different sites mentioning that the barnett plates they bought have no dimples.
