im looking at the 99 x1 lightning i might buy, but it has a problem after its been running a while, the owner thinks it might be a bad ignition control module, heres what he discribes its doing:

The mods to the engine are as follows: a screamin eagle air cleaner, buell factory race ECM, d & d exhaust, and a oil breather. The problem starts after riding for about twenty or so miles. Sometimes less sometimes more. What happens is when accelerating it starts to cough or skip and if you let off and the apply the throttle againg it smooths out but when you come to a stop it will start to idle hard. Then the process will repeat. It will do this for a while and then have the urge to want to cut of or stall with a backfire. I have never had to traer it home always made it just with a little trouble. My buddy who I ride with and was behind me said he saw a little white smoke when I would accelerate and could smell gas like it was running too rich. That's about it. Before the twenty or so miles it runs and Idles great.

any ideas? btw it has 20k miles

Check the engine temp sensor and the wires going to it. This will cause the bike to run like this and it is a cheap fix. I had the same problem on an x1 and i tried everything until i finally took it to the dealer.

I'm not sure what it look like since I let the dealer fix it, but I believe the part is cheap. You might replace it anyways, you never know if there is something internally wrong with it.
