Installation tips: check compatibility with your model before installation, clean the jet well and the carburetion chamber, and tighten without forcing to avoid damaging the part. Changing a jet is part of the fine adjustments that affect richness, consumption, and acceleration feel — ideal for achieving clean carburation and a more consistent response during your rides or track sessions.

Always replace worn or clogged jets to ensure stable carburation and smooth operation of your engine. For any intervention, prefer a professional if you are not comfortable with disassembling the carburetor.
