Does anyone have a clear and easy step by step with pics of how tot do the kleen air mod (for Stunting to prevent hydro locking the motor) for the 03 R6. \r\n \r\n \n \nNot trying to beat a dead horse just trying to get some clearification. some say block offs and others say a T conector....

\r\n \r\n This is the one Im planning on doing
\n
\nHere\'s the link...
\n
\n
\nThis may work for other years, but is based on an 03. Credit goes out to Greg Moon for his insight on this one.
\n
\n(1) Remove the AIS solenoid pictured below. Ziptie back the connector so it doesn\'t end up in your cooling fan.
\n
\n(2) Remove hoses #1 and #2 from the solenoid, you will be reusing them.
\n
\n
\n
\n(3) Reconnect #1 and #2 back to the nipples on the two breather covers on top of the motor.
\n
\n(3) Using a plastic or brass T fitting found at either your hardware store or auto parts store, connect #1 and #2 to #4. (#4 is roughly 2.5 to 3 feet long)
\n
\n(4) Connect the remaining end of #4 to the crankcase vent located behind the throttle bodies and facing straight up.
\n
\n(5) ****EDIT***** Do not add the #3 hose...leave the two nipples connected to the air box!
\n
\n(6) Cap off the 2 inlets on the airbox where the hoses used to hook up.
\n
\n
\n
\nThat\'s it, you\'re done

\r\n \r\n first things first if you unplug the valve in those directions and it stay open you may not even need to replace the valve with a t , easiest way to check is to just blow through it and if it\'s open you can use it as a t fitting just make sure the electric plug isnt connected ..
\n
\nthe purpose of this mod is to simply bypass the air box so no oil can get in there and as a bonus you will also gain some performance from this mod because it not only stops hot oily air from getting in your air box but it also creates a vacuum in the crankcase and that makes the bikes low end better ..
\n
\nit makes a vacuum because there are one way reed valves under the ports that the two short hoses are connected to and they are ported to the exhaust..
\n
\n easy way to see if you have done the mod correctly is to pull your oil filler cap off and cover it with your hand , you should feel suction on your hand when you rev the bike ..\r\n
