You need to check valves regular ,we found on 250 f that get ridden hard the inlet valves are buggered at around 50 hrs mark , you need good seats put in the head and keep a eye on the guides as well , air cleaner and oil and filter maintenance goes along way on these bikes , a hour meter is a must , you don,t realize how many hrs you clock up .these bikes are reliable if you keep the parts and maintenance up to them , if you don,t it will cost you .
