Hello Friends:

This is my first post here. I just obtained a 1974 Sportster XLH (1000cc). I've been working on bikes for over 25 years but I've notworked on a S&S carb.

My question is this: My sporty tops out at around 5000rpms (no matter the gear I'm in). The idle is fine and accelleration is fine but I can't get it to "open-up".

I know the dude I purchased it from just replace the carb. The carb that is currently on the bike is a S&S 330. The carb-throat has the word "Shorty" stamped on it.

Is it probable that the main jet is too small? I have a lot of experience with Mikuni carbs but none on S&S. Is there a site where I can see the schematics for this 330-carb?

Thanks much for any input: dtkid

 

You might check out the following for information on the S&S carb settings.

Also, S&S used the 'Shorty' description on different models. For the most part the it was used on the Super E's (1 7/8") and Super G's (2 1/16").

 

If I had to guess, I would guess RICH.

 

Hello and welcome from Tucson. Don't know the answer to your question but hope you get it taken care of soon.
