I have a 2001 Harley Sportster XLH big bore. I have been working off and on for about 15 months. Originally it would start up and then after 3 miles of riding it would kick back a bunch and then die. First I thought it was fuel issue and drained the tank since it did sit for a little while (while sitting it had stabil in it). After that, no change. Ran some sea foam in it. No change. Check the spark plugs, and they were dark. Change spark plugs and wires. No change. Thought back to the fuel issue. I bought it with about 29k on it, and it has about 30k on it now. So I looked at the Carb, and it was pretty dirty. So I rebuilt the carb, and the Carb was super clean and ready go. Change for the worse, it wasn't starting at all. I thought I really screwed something else up when cleaning the carb. Then I hit a wall and took it to harley dealer. Turns out Stator was fried and it frying the ignition module. Both were replaced as well as 30k check up. It was really cold and rainy day when I picked up from the dealer. It was pretty difficult to start, but thought it just was due to the cold/weather. However, since then it still takes a lot to start it. Choke doesn't seem to do anything when attempting to start it. It will immediately turnover, and then sputter out. If i keep revving it, it will keep going and it will continue to kickback and will have erratic RPMs. Once the bike warms up, it runs like a champ with no issues. From some research online, I gathered it might be an intake manifold leak. I recently tried to check but a couple of the bolts were kicking my a$$. Before I get too crazy, I wanted to get some opinions if I am on the right track. Thanks. I was hoping to figure this out without going back to the dealer. It is about 2 hour ride, and I am hoping to not spend a fortune.

Maybe a stupid question... Is the choke mechanically working?

Certain Sportster models were known for what you are talking about.
