This Friday Im trading my 04 636 for an 07 Fe550 that's been converted to supermoto. Comes with 2 sets of wheels/tires one for dirt and one for SM. The previous owner says the bike has about 50 hours on it. Oil every 5-7 and valves every other oil change and done at 45 hours. Is there anything I should be super aware of when picking it up. Common problems with the model etc? I haven't had a thumper since 2000 when i got outa dirt and into street bikes. Thanks guys.
