Firebolt XB9R 2003 engine issue

[pauloj]

I bought a XB9R, and when on the run, it makes a hiccup for a fraction of a second when accelerating, and then the engine powers up again. Any suggestions, it seems to be a well known issue. Someone said to replace the sensor, but which one (temperature, O2, ASM...?) Thanks

it is NOT a "well-known" issue. before you start randomly throwing parts at it let me ask you a few questions:
1-do you have the factory service manual for it?
2-have you ever worked on a buell XB?
3-how heavily is it modded? most all are.
4-have you checked your ecm(engine control module/computer) for any stored fault codes?
5-do you have an active or random CEL? acronym for check engine light.
answer above and i'll provide suggestions and solutions.
here's your free #1 if answer is no. http://buellmods.com/

Check your battery connections if you haven't

I'd be curious to see the development of this. I have a similar issue, and I am currently following the lead of an electrical issue. Make sure to provide enough information as requested by lunaticfringe so we can help you out more!

I'd be looking at the kick stand and clutch switches.
