pipe without new pilot jet

[04'400ex'er]

Will it hurt my motor if I run a 160 main with the stock pilot for a HMF full k&n and no lid at 800ft. Or will it just not idle well. Because I cannot get a hold of a pilot until a week or so after I get the pipe. any help is appreciated.

you should be fine,just turn the fuel screw out(richen) a half turn or so if you need to.if your motor backfires on deceleration then you have a lean condition,thats when you want to richen it up some.otherwise i wouldnt worry about is,you should be fine:)

I didnt think it was a big deal but I wasnt sure. HMF told me to go 3.5 turns out to start with so if it runs bad then I will just go to 4 turns or so.
