With just a ev27 cam, S&S shorty/with thunderjet carb tuner ,dyna signle fire and "Python" thunder headers, it takes for ever to warm up, and you cant dog the bike at all. 3&4 gear are a pain, its where its needs the the back pressure the most, and cold start ups.
If you run it like down the strip when riding it runs great. The best way to ride it is to keep the rpm's up. Python thunder headers are tuned exhaust and a good street/drag every day use. Still wish there was $$ to put stock exhaust back on , even trade so some one else can make noise & play with horse power
