Frequently Asked Questions
Fits Mikuni VM round slide carbs (VM26, VM28, VM30, VM34, VM36, VM38, VM40). Also BS30/34 pumper carbs. Check your carb model stamp.
This is a low speed (pilot/slow) jet only. Main jets are larger, like BS30/102 series.
No direct fit. Keihin PE/PD jets are different threading. Use adapter or rejet with Keihin jets.
Use plug chop method: richer black smoke = smaller jet; lean white = larger jet. Or use jet kit calculator based on mods/elevation.
No, single jet only. Reuse stock o-rings or buy Mikuni o-ring kit K464.
