The only thing I have on my Pred is a White Bros pipe and twin air foam filter with stock jets. I prolly will take the top off my air box and just change the jetting. What size main jet should I go to and should I change the pilot jet? For anyone that has done that, is there a noticable difference? Thanks

 

good luck taking the top off your airbox... from what i hear the pred dont run so well with it off [img]i/expressions/face-icon-small-wink.gif[/img] (i suggest keeping it on... you will figure out why)
and if you just got the pipe and filter... id say go to a 157.5 or a 160 MJ, PJ should be fine stock.
the WB pipe doesnt call for any rejetting anyway... but i still think it would help... its letting out more air... there for it needs more fuel.

 

Oh yeah duhh, I forgot the lid holds the filter in... thanks Hozed!! [img]i/expressions/face-icon-small-blush.gif[/img]

 

lol.. i knew you would figure it out sooner or later.
