Frequently Asked Questions

What carburetors do these fit?

These bleed pilot jets are sized for VM28/486 Mikuni carbs only. Check your carb model before ordering.

Why are they sold in a 4-pack?

A 4-pack provides spares for single or multi-carb setups, and extras for testing different jet sizes during tuning.

Will these improve idle quality?

Correct jet sizing is critical for smooth idle and part-throttle response. If your current idle is rough, a different jet size may help — consult your carb tuning guide.

How do I know if I need a different jet size?

If the engine runs rich or lean at idle, experiment with adjacent sizes (#29 or #31). Start with the manufacturer's recommendation for your engine.
