I have a 2002 Spirit 1100 and sometimes when I push the starter button the starter won't turnover. I'll try it a few more times then for some reason it'll start. I've tightened the battery cables, but does'nt matter if engine is cold or warm. I have a Stebel horn and a light bar w/the "Gonz" wireing harness connected to the battery. Bike only has 8500 miles with a 4 month old battery. Thanx for any suggestions.
