Ok, I picked up a 1993 ex250 off ebay for cheap, it's got new carbs and a tune up.. Etc etc. and they guy says it runs well. The bike has about 16,000 miles on it..... Now here's the deal. Now that I got my new 06 636 my girl decides she wants to ride with me.. BUT I really don't want to go spend 3k on her a new 250 for her to drop it on day one or decide riding just ain't for her.. So I get this used bike and let her try it out first.. If she likes I'll buy her something nice.. Plus ever since I got my 98 250 in 98 I have been wanting to use the motor/trans out of one and build me a sick ass little go cart.. So I'll let her try it then this 93 will get frankenstine'd into a bad ass gocart and the remaining parts sold on ebay.. What I am looking for is some advice.. with those sort of miles I know I need to check the tires and make sure they are very fresh or replace them, I am also guessing I want to check the front and rear sprocket for wear and the chain.. what other things am I going to want to look at to make the bike very safe for her...
