i only pay $16 for the last oring kit. but anyway, i got it running with no leaks finally. had a cutting out prob at 1st on friday, find out that the plugs i was using when it blew were shot from the piston frying it. put the old plugs in (still in good shape, just not irdium (sp) ) and prob solved. ran good all night saturday (took it to another party, no one else rode it but me this time) sunday had probs though. a wire on my key switch busted, so i just crossed the wire before the switch and were up and running again. also had a little trouble with it cutting out and acting liek it wasnt getting enough gas in the trail. took it out on the pavement and opened it and havent had a lick of trouble since then, rode for like 3 more hrs after that, so idk. its running good and thats all im worried about. thanks for the help guys
