You were dead on 414.Shifting is way shorter on the 500 and yes it does like to continue pulling through the gears not flattening out like the 250.The bad>the lectron didn,t work out so well,pretty sure it sucked the bowl dry on long pulls just going into 5th as it would spit sputter and has to shut it down.Gonna go back to the pwk for now and see how that works.Any idea on jetting with the Q pipe V1.0?39mm Pwk.With the PT Pipe I,m at 58 pilot and 280 main which is a tad on the rich side.Q pipe will be here in the next week or 2 I think.

What size Lectron is it?  What metering rod is installed?  Does it have an adjustable power jet?  What throttle position were you at when it started to sputter?  If you were running through the gears then pinned the throttle when you hit fifth, you might just be too rich on the power jet.
