To feed your LT250 more fuel, the Trinity R&D department offers the Keihin 39mm. Remember, just bolting up a bigger carb can actually make your 500 lose performance. Trinity engineers were able to overcome flow problems by designing a velocity tube that sets back the intake, channeling the airflow into the carb. Also included is an Outerwear-wrap that protects your new K&N filter from sand, dirt, and grit. Trinity's stainless steel and coated throttle cable (thumb or twist) replaces your stock unit. Gaskets and hardware are included, as are a selection of jets for fine tuning.
