I cut Kimmy's air box and uni-filter, removed the mixture screws with a pink butt splice, slotted the screws and re-installed. We went on a night ride, and there's nothing quite like seeing your wife on her bike spitting fire out both tailpipes on de-cel. I brought the screws out to 3.5 turns, no help, on de-cell, around 3500 you get the "shot-gun" blast from the left pipe mainly...I rode it into work this morning, and the timing was perfect, right when I went through an underpass "KA-POW"...hilarious...will have to up the mains I guess...or something.
