I have a 2006 lbz and I just changed my oil, oil filter, tranny filter, and Fuel filter and when I finished the check engine light came on. Is that normal after doing a service? Is there any way that I can reset it?

No it is not normal. Might want to take it to an AutoZone or O'reily and have the codes read and cleared. See what caused it and post back the results.

Go get it checked, but I believe 30 or 40 cycles of the ignition will clear the CEL. Double check you got the sensor on the fuel filter put on snug, it's kinda hard to get with the location it is in.
