Tulip / DELLORTO venturi improvement adapter Ø38mm threaded X Ø60mm for PHBL

Here is a very interesting product for owners of PHBL carburettors anxious to improve their performance. This accessory will allow you to change your air inlet diameter (tulip) from a threaded Ø38mm so M38 to a Ø60mm with an anti-slip lip of Ø62mm.



This article is mounted on all PHBL carburettors from 24 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.
