I have a lot more punch more bottom-end & more control speed out of a low end 3-port engine, don't get me wrong, the WS-9 is a bad ass engine... and I love "RB" motors. Just a little stumped

on tuning of this bottom-end.
It's not a fuel tune issue... I believe it's about finding the right pipe!
I've tried the, RB-2045, JP-2 & the AE-2035.
Any help would be awesome, Thanks, T.
WS engines are a shorter stroke Buggy engine, they never will have great bottom end for a Truggy...no matter what you do it will be soft on the bottom...they are top end Buggy engines...not Truggy engines....
