i went into my garage today and started up my 88 blaster and i was letting it warm up because i was going to ride a bit. then i started giving it some gas and it made a kind of cranking sound like everything locked up. then i couldn't push the kickstarted down. i gave it a hard kick and it went. but there was no compression whatsoever. also you have to rock it back and forth to find first gear. i need some help.
