inthemail Posted December 22, 2007 Report Share Posted December 22, 2007 i did a few frame mods (removed some baloney ya know) and acidentally chopped off my tabs that hold the airbox in, i had cut up the airbox to make sort of an open intake (see pic) ok. so scrap the intake all togeather, WHEN i jetted the bike i installed 320 mains and did a plug chop at about +24 degrees celcius, late summer temperatures and it was dead on perfect. i plan riding over the holidays and its about -5 degrees celcius. i KNOW im going to be lean without the intake but im just wondering how bad it will be considering the tempereture is so much lower now than in summer. should i risk a few short runs or will the jetting be way to far off? do you guys rejet lower in colder temps?

350BANSHEE350 Posted December 22, 2007 Report Share Posted December 22, 2007 well if just takin the lid off does a load of difference and is needed to be rejeted if you do o then imagine how much better flow you get with the whole unit off your pretty much running one big pod filter if it was still 24 degress celcius then you would need to rejet with that kind of mod now since its colder wether you DEFINATLY need to rejet so go from 320 to oh maybe try 360 do a plug chop and go from there Quote Link to comment Share on other sites More sharing options...
Michael Jackson Posted December 22, 2007 Report Share Posted December 22, 2007 well you kind of answered your ownm question... since you say the jetting was "Dead on perfect" during the summer.. its gona be leaner than the olsen twins in the winter.. and...its bologna Quote Link to comment Share on other sites More sharing options...

shee rips Posted December 23, 2007 Report Share Posted December 23, 2007 jet as if u had pods.... maybe 1-2 sizes less.... when you open up the intake(or exhaust) you have to jet bigger.... Quote Link to comment Share on other sites More sharing options...
HotCarl Posted December 23, 2007 Report Share Posted December 23, 2007 get some pod filters and throw your air box shit away, you are just asking for dirt to get in there. Quote Link to comment Share on other sites More sharing options...
inthemail Posted December 24, 2007 Author Report Share Posted December 24, 2007 ok. so the question has been sort of answered, ill try again simpler. colder outside temperetures = less oxygen in the air correct? so, i need larger jets for thinner air?

Yes in the winter you have to rejet or you will be running lean... I usually run my bike alittle rich so I dont have to rejet in the winter, I just leave it... So yes you will have to go bigger without you airbox and especially bc Its cold...Like said above, If you where running a 320 before I would go up acouple sizes and do a chop....
