Purge kit on a street Bike ?

Well im sure alot of us have seen these NOS purge kits on the imports and muscle cars but how bout on a street bike? FYI you can run these purge kits with only compressed CO2 and get the same effect (Search purge kits on ebay for the best deal most being under $100 dollars) also a 10 or 20 oz paintball CO2 tank works great with this setup and saves you big $$$
