Thanks stopintime. I was leaning toward just replacing the clutch with OEM or Barnett plates and getting the ducabike pressure plate. I just didn't know if the slipper clutch would be a good option for the extra cost.
I don't take the bike to the track and never had the rear wheel slip during down shifting, but if I was going to switch out the clutch for the EVR not would be the time.
I was told that I may need to replace the basket with the plates, but I was asking for high/low estimate over the phone, so I think the service guy was just covering his bases. I'm 90% sure I'm not getting the EVR. Like you said the OEM is a like a slipper clutch. Plus I think the gold pressure plate will tie the bike together nicely
