Keith, I've been riding my Harley a little more lately than the Speedie. I guess thats why when I get on the Speedie I just think its getting faster!!! Actually, the Harley (2005 Springer FX) pulls like a tractor on steroids - up to about 3,500 rpms, then they just run out of power. The Speedie is gagging for gas at 3,500 and wants to be rung out. Maybe I just have gotten used to the Harleys rather undramatic power curve and think that the SPeedie is getting quicker, but it does seem to be pulling much harder lately.
