I had my runs with katana600, GSX750R's and Busa. BUSA only good for straight line runs. I'l rather go fast on water then a street bike. so i sold the busa and bought the ski jet. May be you guys owned a bike and never worked on it. I did my own tunnings and wearout parts replacements. So i know what to expect from what bike. If i were to buy a bike again, it probably be a GSX1000R.
Katana's probably the slowest bike i ever owned. i really dont like the aircooled concepts anyways.
