Guys,
Dynojet kits generally consist of a needle, main jet, and spring for each carb, as well as a drill bit to enlarge the slide lift holes. What is the effect of enlarging those holes? What if I put in the parts but don't drill the slides?
It seems to me that enlarging the holes will increase the RATE of slide lift, but not the overall lift. Will that have more effect on airflow or fuel flow? Could NOT drilling it cause a lean stumble on quick throttle opening?
Your opinions please!
Thanks,
Jeremy
