Right bend pipes

you may hear 50 different theories on that subject, bottom line is right bend pipes flat out pull harder and longer, IMO.
keep that LRD, i've tried 4 different right bends, the LRD was a close second to my Trinity/CT.

I might trade/sale this toomey i have on the black bike now for another right bend.
 
I think it has to do with less bends. Right bends just go over up and out, where as left have to go down over up turn and out. making the design slightly less efficient

Yep , more bends in a 2 stroke pipe causes too many different pressure waves for an ideal powerband.
