Fuel boiling/percolation

[dtmmil]

What are people doing for fuel percolation on the carbed bikes? I ran my fuel line up high between the jugs over to the carb, down around the front to try to help, even put a heat reflective sleeve over it. Im guessing the carb is heat soaking.

If it's an S&S carb, do you have the fiber spacer block, with the O-ring between the intake manifold and carb ? Also, what are you using for an air cleaner ?

Not sure on the spacer, havent had the carb off. And using the teardrop air cleaner.

Its an S&S super G carb and i believe the fiber block and yes there is an oring.

It seems that you have the insulator block, and a decent a/cleaner. Be sure your timing, and jetting is correct, and you have as little as possible blocking air flow.

Is there any other insulators? Thicker etc? Im dealing with the same issue on my carbureted daily driver truck, its getting converted to efi.

I see theres a 3/8” thick spacer, not sure if 1/8” is enough but i might give it a shot
