If you want to preserve low consumption while having more performance than with a SHA or other model for endurance or the road for example, the PHBG model will be a very good compromise.

This low-cost carburetor is of very high quality and has a multitude of adjustments: richness screw, idle jet, needle valve ... This model is the AS (also exists in BD, AD, DS, DD, black model edition, or BS), it is rigidly mounted with a lever, you can also switch it to a cable starter without difficulty.

Compared to the SHA carburetor, this model is much more precise, efficient in recovery, acceleration and peak speed. This model does not have separate lubrication.

Advice : accompany it with a 19 or 20mm pipe, carbon valve slats, pipe as much as possible aligned with the valves, you can simply use an original air filter but also a horn. Provide a range of nozzles from 86 to 100 depending on the filter used.
