Tulip / DELLORTO venturi improvement adapter Ø43mm threaded X Ø60mm for PHBH / PHBL

Here is a very interesting product for owners of PHBH / PHBL carburetors anxious to improve their performance. This accessory will allow you to change your air inlet diameter (tulip) from a Ø43mm to a Ø60mm with an anti-slip lip of Ø62mm.



This article is mounted on all PHBH / PHBL carburetors from 26 to 30mm. Provided that your carburetor is threaded at the level of the air inlet to be able to fix this tulip. This will therefore improve the venturi effect and allow you to install the large intake horn or Ø60mm air box.
