Ill see how my dirt bike sells and if i get what i want for it i might check this bike out then. How much are they worth? I only like to buy bikes i know i can get at least my money back out of it. Hence why i usually only pick up the 50$ "think the carb just needs a cleaning" bikes
Usually those bikes that are missing chains and only a carb clean bikes are usually headaches in disguise but a fun hobby if ya got the skillz,,money and time to rebuild them.............
Those bikes new go for $600-$650 brand new,,,,,,$200 is good like I said if it runs....If not its more worth $150.00--$125.00
Watercooled bikes are a crapshoot,,,it may need a simple head gasket or it could need a topend,,carb rejet and reeds,,,the worst case scenario it needs a topend,clutch and waterpump seals/belt and crank..............

...Good Luck
