I just got back from the college rez were I argued with two guys about how many top ends my cr 250r has gone through. This guy who has never seen my bike garantees me it is on its on at least its 3rd top end not its second like i have said. I have a deploma in cnc machining so i might know a thing or two about metal parts a wear. I just had to laugh at this guy and his friend trying to make me look like an idiot. Have you ever ran into anyone who knows too much for their own good and thinks they are an expert? I have to admit these guys knew about bikes but an statement about my bike which they ahve never seen is a pretty bold one dont you think?
