Question about Buell X1 lightning Motorcycles

1 Answer

I have a 99 buell lightning that is having an issue. It starts well just doesn't stay running. The fuel pressure stays at a steady 50 psi. it backfires a little when running but only runs for a15-20 seconds before it dies. The oxygen sensor is new and the head was recently removed to have a exhaust stud replaced after it broke off. Not sure where to check next. the fuses are fine and seems to be firing right when it does run. Any help would be greatly appreciated.

Check for any gasket leaks. Make sure carb is removed and thuroughly cleaned out. Then make sure it is properly adjusted. Make sure valves are properly adjusted as well.

I have a 96 jeep cherokee and it runs for a while until it gets hot then it stalls. What is wrong with my car?

a number of things can cause your issue. begin by testing fuel pressure. should be at 45-50 psi and hold steady for at least 5 min after shutting off engine.. if pressure is with in parameters then check ASD relay in fuse block under the hood. you can swap it with the transmission relay to see if your jeep will stay running or just replace it they are only 10. if those all check ok then you most likely have a crank and or cam sensor going bad.. is the check engine light on? scan it for codes and that will send you in the right direction..
