Drag pipe,

I keep jetting information for CVs on my photo web site. You can find them here:

PANHEAD:

Slow Jet: #50
Main Jet: #175
Needle Jet: 0.115
Needle Type: N86E
Idle Mix Location: 2 turns

Engine Specs:
Displacement: 74c.i. +0.060
Cam: Crane 296A
Compression: 8.5:1
Exhaust: Free Flowing (upsweeps with 22" baffles)

SHOVELHEAD (recommendations from those who have done it, not my personal experience):

Same as Panhead except the following:

Main Jet: #170

KNUCKLEHEAD (recommendations from those who have done it, not my personal experience):

Same as Panhead except the following:

Slow Jet: #48
Main Jet: #180

I run this jetting year round. Our winter is probably closer to your summer but this jetting works fine winter or summer here.
