Frequently Asked Questions
Fits Mikuni TM and VM series round slide carbs (BS32/34/36/38SS, VM26/32/34/36/38). Check your carb model markings.
This is a low speed main jet (needle jet position) for fine-tuning mid-range fueling, not pilot or high speed.
Single jets are for precise tuning. Consider a full Mikuni jet kit for complete range (e.g., #98-118 sizes).
No, Mikuni jets have different threading. Use Keihin jets for OEM Keihin carbs or confirm conversion kit.
Use plug chop method: richer black smoke = smaller jet; lean white = larger. Or use Mikuni jetting charts by elevation/temp.
