For anybody who has switched to 19/46 gearing on their 12' pro 800 163 as their only mod, what did you notice? Better, worse, or the same. Thanks

I run 19/43 in both of our pro's with custom cut helix and I believe it is a red/black spring. Have a PA head and HPS can running 64's and stock primary at 3-6000'. After several good pull up the hills the clutches are warm, but can hold bare hands on them easily enough. Both clutches are about the same temp to the touch. 600 miles on original belt and it still looks like new with almost no visible belt dust anywhere. Clutching is working good and holds rpm's very well, but may try a tied this year for the heck of it.
