It does have an effect but not in an area that I'd find useful. Pointy SV650 is retarded in the lower gears at under 4k rpm and under half throttle - just enough to sneak through the noise regs, allegedly.

Now I dunno about other riders, but if I'm at under 4k revs with the throttle less than half open, I'm not expecting my engine to perform. And even on the rare occasion that I did suddenly decide I wanted to go faster, whilst at the same time being too lazy to change gear, I'd open the throttle more than half way.

The only conceivable advantage is that it might smooth out the snatchy throttle pick-up. Also makes tick-over slightly louder.
