I have a 92 Softail that was stalling at idle and backfiring when I let off the gas. I changed out the jets and the manifold seals and the backfiring stopped but now I've got a new problem. Once it gets up to about 55 and I keep it there, it starts to sputter and sometimes completely cuts out. It seems like it's starving for fuel. I had blown some compressed air into the slide piston so I thought maybe I damaged the diaphragm. I changed that out but no luck. I just cleaned the whole carb really well and changed the gasket on the float bowl.
When it starts to sputter, if I lay off the gas for a couple of seconds then roll back onto it it has plenty of gas and get up and go, but then it will sputter again and the whole thing starts over. From a stop it'll take off and get up to speed fine. It's just once I'm up to speed and remaining at a constant speed that I have this problem. It's like my float is sticking or something, but I'm not getting any overflow of fuel when I'm stopped. Somehow I'm using more gas than it's supplying at a constant speed. Kinda stumped and looking for some advice. Thanks in advance for the help.:newsmile07:
