The K57 needle controls fuel delivery through the mid-throttle range (roughly 1\/4 to 3\/4 throttle) by metering fuel flow through the needle jet (R.262042). Needle position is adjustable via the clip (R.245630) across five grooves — raising the clip leans the mixture, lowering it richens it.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with the Dell'Orto VHSB 34 XS (R.295060) fitted to all Rotax 125 MAX EVO variants: \u003cstrong\u003eSenior MAX EVO, Junior MAX EVO, Mini MAX EVO, and Micro MAX EVO\u003c\/strong\u003e.
