This set of 48mm came off a road race only 2.0. HAM heads, Tangerine exhaust, 12 to 1 compression, Jenvey stacks, etc Dynoed 142 at the rear wheel. Pulled hard to 7100 or so, but best was about 6500. Came on about 34-3600 and peaked at 58-5900, been to long to remember. Torque was pretty flat due to wider lobe center on cam.
40 vents
160 mains
60 idles
55 squirters
Can't remember the jet for the high speed circuit, but a jet from a smalll Dellorto carb for motorcycle fits. The AFR was too rich on top, so we put the smallest jet available. That adjustment leveled the AFR to about 12.7
I know lots of folks use Webers, I just had better luck with the Dells. Car sold due to health reasons. Dallas area. There are 3 sets on samba, each for over $1100. $850.00 plus shipping.
