Unfortunately there are no intake gaskets on an `89 or earlier, they used those lame butterfly type carbs and the infamous compliance fittings...
OP:
If you are still using the original butterfly type carb, it may be time to think about replacing it, rather then spend money for new compliance fittings, carb rebuild kit etc.

Through the carb, sounds like compliance fittings. They don't last forever. Might as well do a thorough cleaning and refurbish of the carb.
As replied, consider going to the HD (Keihin) CV carb or into the aftermarket with either S&S or Mikuni.
My 93 FLHS was doing the same trick, and after replacing the manifold gaskets and rebuilding the carb, it disappeared.

The guy before me put a screaming eagle carb on it in 2005. so not original. the rubber intake is 1989 though so it will go. Many thanks for the info. I'm gonna do all the things you guys have mentioned. Thanks again for the help. Will get back to ya

S&S E carb
I bought a 1998 flstc in 07 running rough.Took the s&s off to clean it and noticed a missing capscrew on the intake manifold on the front cylinder.Installed the capscrew cleaned the not very dirty carb then set the carb by the S&S videos on you tube and it ran fine.Haven't touched it since and still running fine.
