I been using one of thoes dry shot NOS kits you can get on ebay for cheap I sprayed 10 takes over a period of time of it it my polini and still have 200psi of compression and never had a problem I just upjettted until it just started 4 stroking a lil bit and only use for about 4 secs. but man talk about power it says you get 50% more power up to 5 secs with a fresh tank my bike will pop a wheelie at 50mph and take off like a damn rocket.What a ride.SO far its been good for me.cant dish out $1000 bucks for a wet system.
