No fuel in cylinder #2.... Hmmm

[NatiKiD]

So I have an 80 gs750L. It's only running on 3 cylinders. Sometime #2 will come back, but cuts out shortly after. I know I have spark. What would cause a no fuel condition in one cylinder? (Carbs where professionally cleaned and rebuilt 6 months ago)

Makes no sense to post your same problem in different sections- stick to one. Did you check your petcock? does #2 have a vac connection to this harley petcock? pull #2 spark plug and see what it looks like after some running.

The Harley Petcock is just and on/off style. No vacuum needed. Spark plug dry, so scent of fuel.

Hi,

The term "professionally cleaned" doesn't carry a lot of weight around here.

Either do them yourself or hire one of the guys in this forum who've done hundreds, and done them right. See the "Services" section.


Thank you for your indulgence,

True enough, but in this case, it might.

He was just being polite enough to not name names.

I will be following up wih him soon.

I just checked back in your stats because this all sounded to familiar to me, and have found you have started 3 threads for the same problem since May, and you have yet to except that the carbs are a miss, and your Sportster petcock does not work correctly.You need to go through the carbs again and make sure your floats are adjusted properly[ Man I feel like we are beating a dead horse here ] and if you are running a Sportster petcock and it is not vacuum operated have you plugged the Vacuum port on the #2 carburator?

Fair enough. I'm sure you can get Mr. NatiKid sorted out and on his way to miles of smiles.

Vacuum port is plugged. It doesn't make sene why it runs great when it wants too.
