Hey Joe,
I did notice a difference taking off, but it did NOT feel like it was over lugging the motor to get going. I am sure taking off on a steep hill will be different but I won't know that for sure till I get up to Duluth where there are hills in abundance for this test.
Now I only have a 790 engine, I suspect the 865's have even more reserve in the HP department.
Addendum;
I just went out and did some experimenting.
I did a number of slow start ups and the motor did not feel like it was lugging, I can tell a difference from the 17 tooth, but not such that it would personally concern me.
I did two speed run ups, I ran it up until I hit the Rev Limiter two separate times and same result
First gear hit at 50 mph both times
Second gear hit at 80 mph both times
Third gear hit at 105 both times.
I didn't go into forth as I was testing the limit in each gear and I was out of road.
Someone here knows what the limiter is set at and you can figure a comparison from there with smaller sprockets.
One thing is sure, this sprocket really acts like an extra gear at the top end. By "feel" 4th gear at 55 mph feels more like the bike did in 5th at the same speed and like you should stay in 4th until 60-65 mph it certainly makes the engine run at lower RPM's at 60 plus.
Anyone with a tach that can translate RPM/MPH with this set up can chime in.
