Does anyone know if quad shops will do an over look of your quad if you were buying one used to make sure and tell you the mechanical problems of the quad were what the seller told you?

And would the seller let you take the quad to the shop without buying it?

I am buying a older used 300ex. Are there any specific problem areas to check on the 300 ex or just quad specifics that a untrained eye could see?

 

check all bearings also check to see if the axel is tight. check the oil level and most important check the valves buy listening if it taps really louds u can have some serious problems also ask when was the last time the valves were adjusted if they said they dont know they probably were never done
