Re: ENGINE SWAPS SUCK......big time

the head breathes into the air box
if u have done the tip sensor
and u drop ur bike to the left and it dips on to the nose cone or tank
it could hydro lock as oil pumps into the air box then into the motor

it could just get blown out the making alot of smoke
or stop the engine from turning
or bend valves / rods as u go to start it

so clean air mod is to..........
block the 2 airbox pipe inlets
and plumb the hot crank case air to a old drinks can out of the way....
idealy u could have a very small filter on the end of ur hose pipe / can arrangement
as engines breath in while cooling down.....

if you are talking about an f4i then hook the crank case breather hose[the hose that comes out of the left side of the valve cover] to a plastic t fitting and then replace your clean air valve with the plastic t fitting [clean air valve is the t shaped valve on top of the valve cover that has three hoses going to it] the cap off the two holes that will be left in your airbox ,and thats a proper clean air mod on an f4i ......

you will not only keep oil out of your air box but you will create a vaccum in your crank case and that is free horse power and low end torque....

Re: ENGINE SWAPS SUCK......big time

oh and if the bike smokes alot when you put it on the bar with this mod that just means you have too much oil in it but don't worry because the oil is routed directly to the exhaust ports with this mod so it won't foul your plugs or damage your engine in any way

Re: ENGINE SWAPS SUCK......big time

did you use the clutch while shifting through in a burnout? if not it might have saved the gear. hope you get your ride back together soon!
