my 92 softail runs great when I crank the gas and go through the gears great high rpms prefect,however sometimes it will spit and miss and will not take the gas.If it was a intake leak it would do it all the time.thanks

The first thing I would do is the simple stuff.
Add some sea foam to the fuel in the correct amounts do not over do it run a couple tanks see if it improves. I recommend sea foam because it does not use hasrh additives to work.

It would probably be worse when it was warmed up fully. Try some cleaning additive in the fuel like Smitty said, either sea foam or Marvel mystery oil will work.

I would also check for something grounding out, bare wire which only hits metal ever now and then. I had an 65 panhead which did that and after messing with the carb over and over a friend noiced a wire going to the starter which seem to hit metal only sometimes, like when i had a rider on board.
