I'm looking to purchase a 99 venture, the bike is in very good condition as fr as I can see, sounds good no noises in the engine. the bike has 155000 km on it, what is the average km's for ventures. the owner says maintenance and repairs have always been kept up, with him being a mechanic he says he's a bit picky. his asking price is $5600, the only other option that I would want that I don't see with the bike is a drivers back rest. Looking for a little knowledgeable input
