They still make that thing? Having tried one in the 80's on a 2 stroke I can say it did absolutely nothing. As worthless as boost bottles, splitfire spark plugs, and most aftermarket pipes and reeds. Always wonder how the manufacture can refine and test for years and after a new bike hits the market, kazaam... 1 lousy month later FMF and the likes have a new pipe etc. that is so much better than the original. And the louses at dirt Bike endorse the stuff. Something stinks around here, think I'll get some fresh air.
