2 more cents....
i've noticed over the years, that when people add multi-stage reeds(thru power reeds, a RAD valve, or ESR valve.etc.).
They don't follow instructions!
9 times out of 10, the trike is over-jetted on the main(due to increased air-flow).
when installing ANY of the above mods, remember to DROP the main jet 1-3 sizes, depending on the plug-chop(its in the instructions).
On a side-bar........
I'm not sure, Mr Sandman, but can plug-chops also help to determine correct needle height after the main is jetted in?
Following plug-chop instructions, but at half throttle.
Hope any of this helps anybody out there.
