Check out the above thread/link for additional assistance/tips.
And definitely follow lunatics advice. You can’t search google for a Buell Xb related topic without finding his name in a thread or two. The man knows these machines
Also, a great tip when threading the spark plugs by hand, is to use some sort or rubber tubing to get the spark plug started. Put the end of the spark plug(where the spark plug wire attatches) in the rubber tubing as you twist the opposite end of the tubing to get the threads started. Tubing needs to be on the spark plug just snug enough that the tube binds and comes loose IF a plug starts cross threading.
Hope this helps
Good luck
