this was installed on a Hayabusa I got but was never used. bottle has never had gas in it I dont believe. The reason I say this is that no thread sealant was on any fittings and the solenoid was backwards. it was just for show I believe. Intimidation factor in my opinion. So unit is like new you could say. You will need to supply wiring but it has the micro switch to set it up to activate at wide open throttle and #16 jets in each leg for each intake port. they average an increase of 9hp for each cylinder. 40hp kit its called. everything that was on my bike you will get. off of a 05 Hayabusa
