So all you guys out there on shovels, I'm curious to what you have found to be the best carb to run. I'm mainly concerned with responsiveness/performance and not so worried about ease of use or adjustment.

The S&S E's are about as good as they get.

If you want to run a stock carb, Keheins (however it's spelled) off late shovels and early Evo's will work ok too. I never tried a CV, but I know you can get good results with them on an Evo, no reason they wouldn't work on a shovel too.

I'm running an E right now. And more then likely I just don't have it set up right. But it's not the most responsive carb I've ever used. It works great if you are WOT and want to dump fuel in the chamber but other then that it's kind of slow to respond.

It's probably just my ignorance though.

I like s&s e becuase its simple...if you want more performance and tunability you could always add a thunder-jet to it.

I run an S&S "e". When I want my motor to respond I usually need to down shift or slip the clutch 'cause my shits geared for the long haul.

I'm running a CV. Runs fine for my aplication, fairly cheap (about 50 bucks) and some times you can find them laying on the side of the road form all the guys that just HAD to have a S&S on thier Evo.

sounds like it's not adjusted properly I am running a G on my 98" Shovel and I have no problem what so ever....most people buy it throw it on and call it good...alot of adjustments and jet changes will make it ball's to the wall performance...adjust your air first then you need to adjust your accelerator pump till no black smoke comes out when you twist the throttle and if you still don't have it change your main jet up or down it will be no slouch anywhere through the power band unless if your running to big of a cam and or timing is messed up...try that...

For the money $25 or so, it's the keihin butterfly. You can turn the slow speed screw out about 4 turns and ret up up a couple of sizes larger and it's a good carb. You may need to hacksaw the tit off the top of the carb to expose the screw however on the later model ones. One drawback however is once the slowspeed circuit is worn out the carbs trashed because it's made from aluminum. and all the keihins were lean from the factory so if you changed pipes or airclearns or timing, they coughed. But that can be fixed with the mods listed above. About the best new carb in my opinion is the Super E. Easy to tune and jet and spare parts are in abundance. The old BEndix carbs are nice but the new adjustable mainjet ones are junk as the adjustable screw leaks air.

i've got a "B" on my '76, it works fine. not the best responsiveness but the bike starts and runs good. If I had to buy a new one, "E" or SU. $.02

E's if you got the bread.
B's if it's in good shape and you got the electric button and some cam.
CV's work great too (also cheap)
Bendix in good shape for a kick only scoot on a budget.
Mikuni if you are rich and tuning genius.
