Going Pumpless. 1 Month, 1 Week ago  
Since I have everything apart and the Fuel pump off( and I like what it looks like that way , Im thinking of doing the Small Carb mod to the Needle valve seat suggested in the Tech articles . Have any of you removed your fuel pump and just let gravity cake care of it . Noticed my friends old Shovel head Custom is pumpless and it runs like a scared rabbit .

I don’t believe the bowl on the stock carb is large enough to hold the fuel that the bike needs to run at its best. You would have to go with a Mikuni 42 mm I did and love it

Re:Going Pumpless. 1 Month, 1 Week ago  
I did just like the tech article states and put in the float needle. It was very easy to do and the bike runs as good as ever. I also vented the fuel cap at the same time. I wished I would have known that one a couple years ago, before I walked out and found my tank imploded.

Pumpless with the cap vented. No problems. Have the stock carb setup (non-ported, stock jets, etc.) though. Runs just fine.

Re:Going Pumpless. 1 Month, 1 Week ago  
I only removed the pump... didn't vent the tank, didn't modify or replaced the needle valve... nuthin'!

Oh, I did cut the main fuel feed of the petcock by 1/2", and everything runs and works just fine.

If I were a high-speed highway runner, or did a lot of WOT riding, I'd probably spring for the bigger needle valve, but since I tried running without that addition first, and experienced no fuel shortage... I'm good to go, sans pump.

Oh, and today it hit 58 and sunny here, so I was out... saw a few other riders as well. I was not alone.

IMO you do not have to go to a 42 carb to go pumpless .Run a search for pumpless and there are many threads that will help you.I run pumpless with a stock carb....Coug

Will doing this totally cut out the possibility for carb puking? If it will, I am in for it next spring as the first priority after getting my motorcycle out of hibernation.

Most likely.......... unless you actually have a problem with the needle valve itself..
