After months of Dyno and road testing our new Stage 1 Modified jet kit is now ready for the late model 1998 to present Katana 600s.
This economical and simple to tune jet kit is designed for modifying the air box with the included K&N replacement filter, cover and velocity ring for extremely increased air flow. The end results are butter smooth power delivery, unreal throttle response and good fuel mileage. You can expect a 4 to 5 HP gain with our slip-on and a full 9 to 10 HP gain with Dales full stepped header system. More mid range can also be expected as well.
The Stage 1 Mod kit includes 3 sets of original Mikuni main jets, mill spec stainless needle shims, stainless allen bolts for the float bowls and Dales timing advancer with gasket for the engine cover. Its a proven fact the advancer adds throttle response and increases fuel economy on the air oil cooled Katana motor. You can also still run 87 to 92 octane fuel without any problem.
