Dellorto PHBG 20mm 2T clamp on carburator kit. These are the perfect upgrade for worn out orginal Dellorto carbs on any 125cc to 175cc engine. You get a more modern design, increased performance and reliability. A far superiour alternative then "upgrading" to a crummy Indian Jetex carb or trying to find replacement parts for a carburetor no longer supported by Dellorto. Clamps onto a reworked original intake manifold just as originals do and can be used with your airbox for a completely stock look. For carb replacement on any 185cc to 210cc engine, we reccommend the Dellorto PHBL 24mm carburetor kits.

To mount the PHBG carburetor you need to have your existing manifold machined down to size. We offer both Series 2 original manifolds and Series 3 original manifolds machined and ready to go. You may also send us your manifold for machining ($25) or as an exchange on any ready-machined manifold ($15 discount). We also carry a full selection of jets and spares.
