secondary butterflys

[spamanglenn]

I logged the behaviour of the secondary butterflys on a gen2 when i rode one last week.interesting to see their behaviour of when they open and when they close and when they are half open etc.Interesting to see their behaviour.A nice feature to have when you want to dial in smooth off/on throttle.
