Want to get the best possible performance, fuel mileage, and tunability out of your carburetted Harley? You need one of these.

The Lectron HD250, HD300, and HD400 carburetors are the definition of bolt on performance, and what's better is they have NO JETS to change, you read that right - no jets. Get all the advantages of a flat slide carb like Mikuni with none of the tuning headaches, these carbs are fully externally adjustable and they automatically adjust for elevation changes because of the proprietary metering rod design. No more losing power and gas mileage when you go for a ride into the mountains.

These kits include the carb, air cleaner adapter (for stock and S&S bolt pattern backing plates), choke cable, throttle cable, a 2-bolt manifold adapter (for S&S style manifolds, will also work with stock Harley carb manifold), Metering rod adjustment tool, and shims to adjust head spacing at the breather bolts.

PLEASE NOTE; The included throttle cable is 33", this will work fine for most Dynas, FXRs, and Sportsters with handlebars up to 12-14". Longer cables are available directly from Lectron.

When using the HD400 kit with the included adapter on an S&S super G manifold, some bikes will have clearance issues with the stock gas tank, carb will stick out more than stock. We reccomend using either the Mikuni manifold or the Ultima spigot mount manifold #278, this will save you a lot of headaches and enable you to use most air cleaners without modifying them.

These carbs will not work with S&S Stealth air cleaners without modification, however they will fit S&S bolt patterns.
