New mixture screw, PHF 32

Post by 900tlc » Sun Jun 05, 2016 10:29 am

I purchased a pair of mixture screws for my 900 GTS, but could not help noticing the end taper being slightly longer (about a 1mm) than the originals. Two questions, A, were they modified by a previous owner,,B, have they been changed by the manufacturer.
The screws came from a genuine Del orto supplier, any clues? The bike runs fine so far,always ran on the rich side of carburation,before changing the screws, have not checked the plugs yet.
Anyone have any thoughts?

There are two types of Phf 32 mixture screws. One for the as/ad models and one for the later cs/cd models.

The c series have a fine cylinderical point at the end. Perhaps you have those?
