im new the forum and new to working on this bike. i just bought a 1980 shovel with an 83" stroker kit for $1500. its a basket case but the entire bike is together and it runs. when i roll on the throttle it runs fine but when i snap the throttle the rpms start to pick up then it bogs and if i hold the gas it stalls if i let go it goes back to an idle. i messed with the accelerator pump screw and it didn't help. could it need to be taken apart and cleaned, is the main jet to big and flooding it? oh and the plugs are black but not fouled out

 

Go to S&S and download a set-up guide for the E. Follow the instructions, and you should only have to make minor adjustments. I'm curious as to what the motor was originally, a 74"? A 80" motor is actually 81.6". Harley had both 74's and 80's in 1980.

 

thats what id do, take it apart and clean it. also note what jets it has. then start from scratch on adjustments.

 

sorry i just went through all the paper work i got with the bike looking to see what it originally was and it doesn't say, but it does say its an 88" stroker not an 83" could it be to much compression and need to get a bigger main jet?

 

i took the carb apart, cleaned it out, rebuilt the accelerator pump and i still have the same problem the jets are 68 & 32

 

One does not "snap " the throttle on an S&S A CV yes S&S like to be rolled on Thank you very much

 

then what good are they because a lot of people i know ride them and if everyone has the same problem then there garbage. and i know they can be tuned in to run fine because like i said every one i know with a shovel has a super e on it and if your going to be rude then dont post because your the type of person that kept me off these things for years

 

K, time to take a breath of air. sqdealgeaorge is quite knowledgeable about shovels. His comment was not meant to be rude. E carbs have an accelerator pump that was/is intended to eliminate the flat spot that troubled those of us with the early B carbs.

Never having run an E carb I can say that the B carb can only be rolled and not snapped.

Did you take the suggestion and go the the S&S site and check their technical section on carb adjustment and tuning? They will give you a starting point. With a modified motor it may take a couple of adjustments to get it right. Means buying a few jets up and down in order to fine tune it.

Are you sure the problem is not the float adjustment? Are you sure you do not have a manifold leak?

 

If you don't get some answers to your questions then I would suggest trying the J&P Forms. There are two guys there that have forgotten more about these bikes than most will ever know. FX and XEA are the one's to ask...they have both been in the industry forever.

I don't think you are providing enough info though for a good opinion to be formed.

You bought it locally? If yes, then I would assume the jets were fine for the previous owner if nothing has been changed (pipes, baffles, mufflers). A change in elevation could require a change in jetting...but this probably isn't the case.

black plugs...oil?

Your compression is good?

Do you see fuel spray from the accel pump?

Then I'd be looking at tuning.

Your spark is bright and blue?

Timing?

Have you changed anything yourself?

 

the bike was bought 10 mins down the road. i dont know the last time it was on the road wherever that might have been or if anything has been changed since. nobody knows the history about this bike im going off the lack of info on the papers i got with it that are a dated e-mail from 1993. plugs are not oil, compression is good, accel pump rebuilt on thanksgiving and seems to work fine with a mist coming out of it, ignition is brand new and bright blue, i have tried tuning it according to s&s and others i have gotten info from, nothing seems to change the original problem the only thing can think of is the secondary jet is to big. from what i can find stock it suppose to be a .295 and i have a .32 and its flooding it. maybe?
