Nighthawk 750, change the oil, oil the chain. Has Hydraulic Valves. I saw one the other day with 93,000 miles on it. Mine has 30000. I have toured two-up, commute 64 miles each way on it, get 44 mpg solo w/ low octane, draged pegs thru deals gap and up Sandia peak. I way 240 and am 6' 2" and the guy who has 93000 on his is like 5' 7". Its a pretty good bike.
