Readjust carburetor to factory break-in settings (Factory Needle Settings)

Pro.15 Engine:
The Carburetor Should be set to 2 1/2 turns on the high speed needle. The low speed needle should be set so that the head of the needle is flush with the end of the carburetor.

 

 

TRX 2.5 / 2.5R / 3.3 Engine:
If your factory preset carburetor adjustments have been tampered with, use the following settings:
1) Set the high-speed needle to 4 turns out from closed.
2) Set the low-speed needle so the screw head (red in Fig. A) is flush (even) with the end of the slide (yellow in Fig. A).

Always use the factory settings for initial starting. Only use these settings when the factory settings have been lost.
