Air box and girdled head

Just finished putting my 09 back together and am trying to figure out what to do about the Air box. I had to cut the stock one so it would clear the girdled head and the last fix did not hold and probably killed my motor. What does everyone do with the air box issue and girdled heads? Would black silicone work (the super tuff crap or would it not stick)...

I think spacers are in order. A buddy took an old set of adapters and milled them flat on top and made his own for cheap. X-Scream and others make billet spacers too if you don't mind spending the $$$.

If you find a set of spacers I have a factory airbox i can sell you. I am going to stick with adapters and proks instead.

care to elaborate? I haven't bought one yet but was thinking of..


Plain box with a big gapping hole facing over the motor. Tack on a 125$ price tag and it seems worthless to me. 125$ is nothing, but it better be a hell of a lot better then what I saw. I am not a cheap part person. Cheap was this crap I did to the air box before, cheap or cheasy cost me 400$ to rebuild my top end. Only rich people can be cheap. Everything on my 09 was brand new, New b pipe, new msd, new girdled head, new xft footholds, good resin from reputable uscompsites. Cheap was this crap I did to the air box before, cheap cost me 400$ to rebuild my top end. Off the soap box now. :veryhappy:

I have had fewer water issues after switching to proks.


It was not water I injested it was harder, last time I injested water I bent a crank and pistons looked perfect (different motor) this was something hard..... I was being a smart ass on my old ski and stayed under to long and didnt give it a chance to pump the water out :( The 09 died from something else.

Just dremel it. As others have said, that area already has a hole (two actually) that lets air in over the head of the engine. All you are doing is slightly modifying that hole's shape, not adding a new hole.

I covered my cut hole with west system and black fiberglass layed like this ......solid and can't come out.....it has held up great.

x2 - I just cut/dremeled around where the middle acorn nut is and its fine, been that way for 2 years. Not sure what the dilemma is here
