Have you ever noticed there is about a 5 degree temp range where your bike just runs and sounds perfect. Tonight was that temp for my RGlide, 69-74F and she runs perfect. Heck even the throttle felt smoother. Ok, that might have to do with the fact I lubed the cables yesterday, lol.....

 

Always seems to be a sweet spot for most motors, most don't see it though.

 

usually its weather conditions when ideal your engine really likes it!!
