crazy thing,so today i decicde to ride.well i had not rode since the harscramble on the 16th.i always check the oil before a ride,well there was no oil coming out of the check hole so i put some in it to top it off.half a quart later i relize something is not right,then i hear it.the oil is pouring out of the bottom of the bike.my oil plug is gone.on further investigation i relize it's stripped out.the thing that freaks me out is that i havn't rode since the race,so i'm sure i lost it on the track.who knows how long i rode with no oil in the case.well i got it tapped out and a new bolt in it,and filled it with oil.i took the bike down the road and everything seemed to be fine.still goes through all the gears,and doesn't rattle,or knock.guess i got lucky
