My main riding buddy has a warrior...He can't ride it right now because he has to do his maintenance...without tearing it down yet we already know it needs rings, timing chain(which I hear is a beotch), possible bore, and a new carb. We're HOPING that he won't need valves or anything else. I tell you what though, I was reading about someone not wanting a used and abused banshee; I bought mine for $500, came with everything except a running engine. EVERYTHING was loose and wore out it seemed. I spent about another $500 and grabbed a good friend of mine to help rebuid it, have had not ONE major problem with it. Only thing I have had to do is routine maintenance, something you should do to every motorized vehicle. I personally think the banshee is REALLY simple to maintain. Even when it comes to an engine rebuild, the hardest part about it is coming up with the money to rebuild it! I'm keeping my shee until I'm too damn old to kick it over!!
