Did all the manufactures of turbo kits quit? I see the kits aren't for sale on KMS, aerocharger, or boondocker. From all of the forums I have read on here I have seen very mixed reviews with them. Seems like people who like to wrench and tinker were satisfied, people that wanted to bolt on and go were not. I'm guessing they quit selling them because they didn't work that well. Part of the thrill of riding for me is speed and torque, and coming from a flatland area, it's a larger part of the riding experience than boon docking. I have ridden a couple different kits, and while enjoyable, it would just be hard for me to invest into one without knowing there is way to get more reliable power out of a bike. Any thoughts?
