Description

If your bike is showing signs of temperamental running, hard starts, or a rough idle, your pilot jets are the likely culprit. You will receive 2x brand new pilot jets (Item #60 in diagrams) to fit both the rear and front carburettors.

The factory fitted pilot jets are sized specifically for each engine capacity. Because 125cc carbs have smaller orifices, they are more susceptible to clogging and buildup. Regular cleaning or replacement of worn pilot jets can resolve many common performance issues.

💎 Performance with Reliability!

Keeping your jets clean and correctly sized ensures smoother, more reliable throttle response and a happier engine overall. This simple replacement can bring your Hyosung back to life if it has been feeling moody or inconsistent.

Cures Rough Idle Restores smooth running at low RPMs.	Fixes Hard Starting Ensures consistent fuel delivery from cold.
Model Specific Sizing Correct size supplied for 125cc or 250cc.	Mikuni Fitment Fits all listed v-twin carb models.
