i bought a used 07 crf250r. Still has the original back tire with %70 tread. It still had gas in it from 2 years ago he said. He also told me he didnt shift with the clutch, and that he revved the shit out of it. It looks like he crashed it a couple times then put it away. Last time i owned a bike my dad did all the work on it. So please tell if i ****ed up. I put some fresh fuel in it, got it started up (rolling start) and i cant get it to idle. it also bogs out in the bottem end when i jam on it hard. So i took the carb off and ripped it apart. Then the valve cover too check valve clearances. Left side intake was .004. I couldnt check the right side intake i dont think i have a small enough feeler but the smallest one .0015 didnt fit. both exhaust were .007. Also i found some nasty scratches (circled in red) I paid $1600 for it and im ready to put money into it, i just didnt expect those deep gouges in the head. And what else should i be looking at that might be busted?
