S&S super E on a shovelhead

[LW Shovel]

I have a 81 superglide with a super E Carb on it and it seems to be hard to get adjusted.Is this too much carb for this motor?

The "E" will work on a stock shovel. What are the jets in it?

[LW Shovel]

I have to find out,Right now it has what it had out of the box.My mech said it has a flat spot when accelerating.

Should'nt be to much carb. I run a Super E on my 64 Pan w/ B grind cam. Probably just needs trying different jets and a good tune. I know someone in Augusta that could help.

.0295 pilot, .072 main, 3 turns out on the pump, and 1 1/2 turns out on the air/idle screw.
This will be a strong baseline, and adjust from there.

The way gas around here is we find the 28.5 and 66 or 68 to work well,
my EVO has an SE4 cam and SE heads and I run the 28.5 / 68.

The signal at the carb, is so sluggish with the a-typical shovel, that more fuel is required across the board.

i ran a super E on my shovel when it was stock 74" with a sifton 440 cam and again as a big bore 88" with an andrews b grind.

I ran slash cut pipes, 1 3/4 drags and two inch drags. I found the carb hard to adjust with the drags...always had a flat spot no matter how it was jetted. S&S says this carb may be finnicky depending on your pipes and air filter set up...

my '83 shovel did 70hp with just bolt ons..no cam.

My biggest tuniing problem was sealing the manifold gaskets. The key is a good BRACE for your super E and good worm gear clamps. Not necessarily aircraft style!

I ran a Yost power tube a single thunder jet, a "turbulator" which i swear helped. I went to MC power arc single fire ignition set to 6.5 K redline.
All "seat of the pants" tuned. No dyno until the very end which ended up just being a measuring device, not a tuning aid.

That engine rans SO well! The valve train held up even...stock!
People thought i had MUCH more work done that I had. I just super tuned what i did have!! Key! Word!

One more note. Do NOT use drag pipes with this set up. The bike will run like crap. Use Cycle shack 3/4 inch slash cut with baffles in. I remove the baffles and bend the large "tab" restricting flow. It is a very very stiff tab. I hammered a solid steel rod thru it to open it up a little. That made a huge difference in the tune. NO BAFFLES worked like crap. Modified baffles really helped the tune. Cycle shack pipes are dirt cheap. Buy new ones and remove the baffles to work on them before they get all carbon ed up. Re installl the baffles after you modify them.

Any questions PM me. But I am telling you I ended up with a chill Shovel for not hardly any extra $$ after the money was spent on all the carb stuff.

i just put a supper E on mine (99 superglide)and added the v&h big radius but have noyt had the chance to ride it yet!! still waiting for the tank to be painted!! then i will ride!!!


but untul then i am keeping up with this tread

I've got a dual throat del ortto on my 81 FXE.
It is set up rich, but is runs well.
running dual pipes with baffels.

I have a heavily tricked out dual throat Weber for my build in progress, a 109 inch Shovel. I think Dual throats with the swept manifolds look really cool. Contrary to popular belief, they CAN be made to perform extremely well. Lots of tuning issues.

I know there was one guy who made manifolds for Weber dual throats with INDIVIDUAL RUNNERS. Very cool IF and ONLY IF the diameter of each throat is large enough to flow the air and fuel needed to make power. Dual 40mm throats are TOO SMALL for many individual runner applications.

You can give each cylinder a MUCH better signal by NOT using a common plenum for mixing each pulse. DUAL throat 48mm Weber is a nice size for say a 107 with heads that really flow!
I forget the company. I am sure you can find individual runner manifolds around. I think Riveara supplies all common plenums still. I am not sure. I have not checked them in ages.

Oh, and as far as I know the manifolds are the same for Del orto and Weber. Arent they?

I am NOT a big fan of rich running Harleys. My car, my bikes are all set up a tad lean. Lean is mean. Rich is safe. Lean can damage motors so be careful. Know what you are doing.

But you get all your crisp throttle response from an motor that is NOT rich.

I dyno tuned for power once. Then I leaned it out for throttle response. I made a tad less power but gained over all performance because the motor spooled up so well.

Dont STARVE your motor, but keep things CRISP! You want that SNAP!

For something really special look into individual runners. I found this in 10 seconds. I am sure their is a ton of info out there.

Yeah, that pipe looks fine.
Again, i want to stress that Super E's can be made to make a LOT more power and better response by taking them futher.
1) Yost power tube
2) TURBULATOR
3) SINGLE THUNDER JET WITH ADJUSTABLE AIR BLEED.
4) K&N AIR FILTER
5) uSE THE STOCK AIR MOUNT AND COVER. The stock mount has a nice raduis on the intake that helps air flow and the enrichner control works well this way.
6) Special attention to NO AIR LEAKS on manifold. This is critical. Use a very solid bracket to help mount/support the carb on the motor.


The thunder jet gives the final circuit that the super E is lacking out of the box. The tuners that dont believe in them simply dont have the patience to tune them properly. But a properly set up Super E will rock your world! It takes a good while to really dial them in PROPERLY.

Will your bike run well with a super E with out all this stuff? Yes, as long as the manifold does not leak. But you are missing out on a LOT of throttle response and power.

Trust me on the turbulator. I swear it helps swirl the intake charge. They are not expensive. Dont bother with the atomiser.
Worse case scenario is that you end up with better fuel mileage from the turbulator. More efficient burning of your intake charge!

For what its worth a few mates in the past have run cv carbs of evo's that most people junked in those years, on there shovels, with good results , you can buy the adaptor or make your own and with a bit of rejetting it is a good alternative

Nothing wrong with a CV, especially if you plan on multi altitude touring. The Rockies will play havoc with a sea level S&S tune.
