Cruisin' Guzzisti
I got a Quill silencer for my '09 Stelvio in 2010 and they kindly dyno'd it for me but only after it was fitted. I always wondered what a stock '09 would do but could never find a dyne chart until a couple of days ago.
My bike only had about 4000 miles on it so not really run in and I suspect it makes more power now than then, especially as I'm running a K&N air filter.
I compared the two charts and rather inexpertly overlaid the Quill results over the stock (from MotorcycleUsa magazine). With the Quill, peak power is down 1.18 hp and peak torque 2.27 lbw-ft up, both around 300 revs lower down. So what, I hear you say - until you look at the change in midrange! Enjoy.
