Carburetor TUN'R PHBG 21 AS rigid, without separate lubrication, choke lever

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

This low-cost TUN'R carburettor 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 edition, or BS), it is rigidly mounted with a lever choke, you can also switch it to a cable choke without difficulty. Compared to the SHA carburettor, this model is much more precise, efficient on recovery, acceleration and peak speed. This model does not have separate lubrication.

*Attention, although it has an aluminum bushel cover, an aluminum tank... It's not really a real DELLORTO ! It is not worth the performance and durability of a real DELLORTO !

Advice : accompany it with a 21 or 19mm pipe, carbon valve slats, pipe aligned as much as possible 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.

The carburettor is delivered as such:
Standard small pitch main jet: 80
 

These accessories can be changed for better settings, although these carburettors are very well preset. All spare parts and adjustments can be found here.
