questions about 2001 buell x1

[citizenx]

So i recently got a 2001 buell x1 and am having some issues. It misses a fire on one of the cylinders from time to time, sometimes this kills the bike. When I am riding between 2-3 rpm at about 1/8 throttle, it will start to sputter out like it is going to die then come back, and then repeat until I give it some more throttle. I have only had the bike about a week and so have only put about 97 miles on it around town, and my fuel light came on. I had to put 4.2 gallons in, equating to about 23mpg. From what I have read this is much lower than I should be. The only thing that I have done at this point is a TPS reset.(did not fix problem)

Mods on bike
D&D exhaust
Race ECM
Forcewinder intake
Crankcase Breather Mod
and few other visual things not relevant

Please let me know what you think might be wrong.

Thanks for your help
Matt

i would check plugs and plug wires. mine ran on one cylinder once and it was the wires

yes check the plugs & replace its cheap, then replace wires if the plug change did not help. Then I would do a coil test with ECMspy and then try to locate a replacement. Then if that doesnt clear it up.....idk haha

I will look in to that, I did replace the plugs(sorry forgot to mention that)... would that effect my mpg that much?

With it not running right it would use a lot more gas. I would definitly try new plug wires next. And since u got a tuber there easy to change anyways
