Critter· Retired twice: Navy and as a govt contractor
Didn't really think you where looking for an answer. One of two possible. Just last week I posted ( How fast is your bike? 95, but will do the ton on Saturday night ) And I asked why is that. No takers as often happens.
1. Cooler air and the bike makes more power
2. A few beers and optimistic reading of the speedo.
