rm 250 bogged out

[canadiancowboy]

hi there, i've got a 80's rm 250, was out the other day ran fine, stopped for lunch and it wouldn't start up again, i had a buddy push me and finally it caught, kept bogging out at low rpm's but at the high end was okay, felt a little different, then it stalled out on me, and couldn't start 'er up eh, any ideas on what's going on? thanks

Check your commpression,fuel flow,plug,pull your ignition side cover off the motor,check crank seal(easy side).Is the tranny oil foaming or overflowing,could be clutch side crank seal,good luck,Bill.
