buy that mofo asap!
All I know is that if you are interested and can get a descent tecate for a good price is: GO FOR IT. These are very rare quads. They have some problems, but u can get good aftermarket parts to fix anything on it. As far as them compared to a 250R, I think the tecate may handle better than u think. With aftermarket shocks it will even maybe be better than an r.
Good luck
