Anyone tried this motor against the JLR? Assuming the RB matrix is very much like the Sirio would there actually be any differences. I'm craving something with more bottom end and was told Novarossi is the way to go. I've seen the prices go down for Sirio, but again not sure what route to go. The JLR may be price worthy for performance...but will it have the bottom end I'm looking for...assuming I couple it with the yellow clutch shoe, LW shoes, and soon MSR hard spring?
