simple intake and jet Q

[CJCaldie]

ok, Ive looked around and im still a little confused. im ordering a pro-design kit. if i pop the top do i re-jet or do i need an aftermarket exhaust first? the exhaust probably wont be till next year. im sitting with stock specs and at 3000 elevation. if i got my info right i would just need a new main jet? ive read a lot of guys say just get a 150 and see how it runs but they are talking to people who plan on putting on the exhaust. i know im not really going to see any improvement until i do the exhaust so maybe just hold off on taking the top off? whats the deal

If your running stock exhaust and no airbox lid at about 3000 elevation you should run a 147.5

finally found two extensive threads about tuning and learned a lot. ill start with the 147.5. should i consider bumping up the pilot at all? i guess ill just let it run and see how it goes but since ill be at the shop...
