OK for racing!
Dellorto PHVA 17.5mm for performance use on 50cc - 70cc scooters. This is a performance carb from this Italian carburetor maker at 17.5 mm. What we like about this carb is that its outside dimensions are about the same as standard, so it fits the same manifold and airboxes on many Honda, Peugeot, Kymco and Daelim plus Suzuki and other scooters using similar type engines.
This carb makes a big difference to your engine's max power output through its superior design and larger internal throat size. We recommend using both a larger manifold and racing air filter for even more performance. Performance reed valves ensure higher power performance too.
Larger carburetors give noticeable increase in max rpm‘s plus more response, which means more power and higher top speeds!
This is a great upgrade for 50cc - 70cc engines. Takes the factory auto-choke unit (on Hondas and Suzuki TR50 [Chassis CA1LB], possibly other models too). Comes fitted with 90 main jet, 35 slow jet and A27 needle (as verified on 9 Feb 2016 - specification is subject to change). Otherwise grab the Dellorto type choke unit we sell separately.
Some modification could be required to throttle cable or air cleaner etc, but for most models this is a bolt-on replacement performance carburettor for a good power increase on your scooter for street or race! Tuning is usually required by a technician or experienced person. This carburettor takes the Dell'Orto 6mm main jets.
