Newb here with some jetting questions


Recommended Posts

Hey gang,

 

New to the forum but not banshee's. I have a 97 shee, dune ported and polished, trinity head with 20cc domes and 28pwks. So I have it jetted for sea level, it's never seen altitude, but in 2 weeks I'm headed to sand mountain which is 3-4000 ft. Any suggestions on what I need to change..pilots/mains. Appreciate the help. Thanks!!!

copy and pasted from the jetting FAQS here...

 

Typically you'll need to rejet your mains one size for every 1500'-2000' elevation difference; jet smaller when going to a higher elevation and jet larger for going to a lower elevation (for example: 300 mains at 3000', 320 mains for 0' or sea level IF the temp is the same)

 

This is for stock carbs, but it's all I know.
