my 650 wasn't starting. we put in a new sprag clutch first off. we got new plugs and tested them and they are getting spark just fine. we cleaned the carb up and put it back together and tried it. still just turning over. we did a compression test (wrong). With just pulling a plug and turning it over. ( i know its wrong now) it was 70. could someone point me in the right direction on what it might be. I'm gonna get the piston and cylinder checked and the valves checked.if those are ok what else could it be. someone told me it was the bent shift forks. could that be it? i really want to get it fixed ASAP
