ok so im new here and need some help....ive been around 4 wheelers alot but never a 2 stroke one, however i currently have a yz 2 stroke bike anyways ive found this 02 blaster for sale this guy wants 550 dollars for it he said it was stolen and when he got it back the motor was locked up and had to use penetrating oil to free it up enough to take the top end off said looks like they ran straight gas in it (he just mixed his gas) got new top end and put rings in and this is its current state still needs put back together.....my ? is do u guys think that the tranny is messed up any or anything with the top end or just the piston and whatnot and would it be worth it thanks for all the help in advance
