Thunder Series Avs Carb Tune 392 Jets
|
On the secondary side, we replaced the original 407 jets with a pair of 392s. On the primary side, the factory 413 jets were replaced with leaner 404s. With the jetting change, power went up to 325 at the wheel, while the average air/fuel ratio leaned out to 12.21:1. More power and less fuel-we like that. View Related Article
