hi, i live across the pond in scotland , needless to say there aint many shovels near me , ive a 81 flt, with andrews cams, stock pistons and super b carb, for the life of me i cant get her to run sweet. obviously its down to the super b as everything else has been renewed, my jetting is the prob, can anyone help ?? wot are the correct jet sizes?? im runnin drag pipes, cheers ,ian
IMO . The best thing you could do for your shovel is put a CV carb on it . I had a Super B on my '81 and could never dial it in just right . The main problem with the Super B is that it doesn't have an accelerator pump , not a good street carb .
Come to think of it I believe I heard that there is an accelerator pump upgrade available for the Super B , that might be an option for ya .
Disclaimer : Don't believe anything I say unless you are absolutely sure that I know what I'm talking about .
40 or 42 CV Carb with a press on adapter for your manifold and it will run better and easy adjust!
The S & S B is a good carb too but I sort of like the accelerator pump too Like the Shorty E S&S has! Maybe the B Carb is a bit to big for your motor too !
CV PERFORMANCE.COM is where you should look and they should be able to get you all the stuff you need to bolt a modified CV Carb with adapter all set up and ready to bolt on your bike! Now the other thing is the pipes your running !
Alot of tuning problems can be fixed with the right pipes, and a little back pressure for a street motor!
Hey I'm from Wisconsin and love to support S&S
but now Im in Colorado and Im switching out my E-Shorty to a CV Carb on my 59 Panhead for the adjustability going from 5000+ ft to 12,000ft in the same day with a turn of a knob as I ride!
But try the set up Kirby gave you above....if it works dont fix it! I used to watch Kirby aka ProDrag1320 race in the midwest and he knows how to "go fast"
all good advice here Its the riders choice on carb preferance I perfer the S&S super shorty E I wouldnt run anything else set it and forget it.but alot of guys like a CV.I like butterfly carbs not slides....Good luck.
I like an E carb as well. I am working on an 80 inch Shovel with a B on it right now. Between the points and the B it is tough to get it to idle right. It seems to have a two step idle. Either 1200 or 600 rpm but NEVER 900. It will idle high for a bit then will settle down to the "too low" stage. I've checked the advance unit out too. What is up with that?
