previous owners mods: stainless headers, yoshi slip-on, what appears to be an unbranded hi-flo air filter, not had the carbs out to see if its been jetted up yet but theres a bit of low-mid range bog at times. tweaks I've made so far: stubby levers, osram night breaker bulb (wow! i can see), forks dropped through an extra 10mm, black double bubble, grab rail off, black lensed mini indicators, k&n oil filter, motul 7100 fully synth (so much smooth!) zx1 metal treatment (even smoother!)
