I've had the KLR250 for 2 years with over 7500 miles +1 on the checking valves- it is not a major deal but DO IT! If this bike has a weak link the valves are it. Check em regularly and you will have very few problems -
don't and you will not be happy.
Tank bag, saddle bags and a home made luggage rack and I can go away for a week. The seat is the limiting factor I really need to do something to make it better for all day riding.
Welcome and enjoy your new ride!
