What did he actually do? to modify the fuel system? tkns
I do an old trick on the intakes that never fails...taking a tip from the best engine builder and innovator in the world...Yamaha. Maybe you old farts like me remember the Yamaha YICS system" It stands for Yamaha Induction Control System...basically a loaded intake plenum....already charged with newly atomized fuel molecules...just waiting to be called upon to be sucked into the combustion chamber and banged off....good idea I sez to meself I'll just pirate this idea and see what cooks out...literally. Cheapskate me goes to the auto parts store and buys about three feet of intake/fuel line, and one brass T....I cut equal lengths of the line and hookemup to the intake manifolds, then Tee off to the petcock.....makes vacuum synching a snap....hook up the old mercury sticks...dial it in....hookerup......MY O MY!!!!
It's so smooth with this YICS system now I can turn down the idle to 800 SMOOTH rpm and the little fella can compete with the bigboy Harleys in the coolguy idle rumble acoustical music category!!
