Hello, I have just purchased a 1999 Royal Enfield 500. The bike has 6,700 miles on it, is currently inspected and has been ridden lightly in the last year. It appears to have the shorter muffler and and non stock air cleaner. The case breather hose has been blocked off with a bolt ( not for much longer though) The engine starts and runs well with no valve noise. It has been serviced within the last year (oil changes etc). Is there anything I should watch out for, inspect or correct before use? How about cooler or cold weather operation? Thanks mtrude
