They were installed in the 2013 CVOs as well. Did something else change with the 14/15 that is contributing to this or do they also slip in the 13s?
Barnett now sells a clutch kit with heavy duty springs for this clutch. Any experience with this? Just wondering if slippage occurring on stock to moderate builds may be fixed by this.
I would like to have a slipper clutch, unfortunately it appears MOCO may have missed the mark on this one.
The same slippage was reported on the 2013 models equipped with the A&S clutch. It was especially evident when people had dyno tuning performed, even with Stage I bikes but especially with higher output mods.
A properly designed slipper clutch wouldn't be a bad idea, but Harley seldom spends the time and money these days to do a proper anything. Other brands have been running properly designed slipper clutches for decades, without issues. Where Harley screwed up was in trying to add the "assist" function to let them reduce the spring pressure and thus the lever effort. The assist function obviously doesn't work well with the cheap and simple steep ramps built in to the system, as opposed to the moving weights used in the aftermarket system. So you have too little spring pressure even for the stock output.
