So i have a Megabomb in the mail, my jetting is Stage 1 dyno jetted for stock header with aftermarket exhaust (Q4).. my question is, (since i cant find my dyno box), how do I change my jetting for this header?

 

what is it cuerently? and what carb do you have?

 

not sure... just got the Dynojet stage 1 and did the option for the stock header.. cant remember

 

its the stock carb

 

I doubt you'll need to jet for the header pipe alone, I didn't. I was at stage two slightly rich and nothing changed with the install.

 

Dynojet has their instrucions free on line.

 

you can make jetting changes really easy by instaling or rigging a temporary a:f gauge and riding around for a while and seeing where it is at in diffrent parts of throttle opening and it's best to do while riding so the motor is loaded
