…...bit of a band-aid indeed and takes up some realestate ! here is a simple kit I set-up several years ago on a drawthrough gsxr…...high pressure pump , nozzle and 1 way valve , adjustable hobbs switch and relay , water/meth tank underseat and pump under battery box ( which was relocated to the swingarm ) ……. worked great for what it's worth but still toasted some pistons just the same .
