Found a 1991 Venture Royale  sitting on the side of the road for sale.  Has 71,000 miles on it  Sign  says everything works properly, Updates done,(???what would they update)  fresh oil change.   
A few questions I have..  What should I look for as thing that I might  see and want to avoid the bike.  How often should carbs have been  cleaned/synched etc.?  How often should the valves be set etc.?  What is  usually the life span of that particular engine?  What would be a fair price? Paint Chrome and plastic all seem in nice shape for a 27 year old scoot.
