i have a 2003 honda cr 250 that wont run. i had been riding it for about an hour than all of a sudden, the engine bogged down and the kick start wouldnt budge. later that day i got the kickstart un stuck and you can move but it wont turn over. it still has good compression. do you know what might be wrong? i havnt taken it apart yet because i know nothing about dirtbike engines and know that if i try to ill just tear it up more.
