John,
I have not been following this thread, so I apologise if I am
repeating someone else's advice.
If you change to K&Ns you also need to uprate the dashpot springs.
The 8 oz (yellow?) ones are the correct ones from memory. With the
increased airflow the needle can shoot up too fast causing lean
running at cruising speeds.
Suggest you sort this out B4 changing needle type.
Regards

Does anyone know where I could lay my hands on an AAA carb needle in a hurry?
I've bent or broken all of Seven Enterprises' stock and Victoria British
doesn't seem to have them.
This was the next recommended step in fixing "rich idle, lean cruise"
syndrome. This expert figures my K&N filters are flowing "too much" at
cruise. He did have the same problem and fixed it with AAA needles on
his HS4s.
I'm using HIFs, but now know how to use the adapters for fixed needles.
I'd prefer biased, but fixed is OK.
(Learning about fixed needle adapters is how I broke the other two needles).
I now have 1 AAE biased needle and 1 AAA fixed needle in the car. It's a
bit confused.
