Hello, everyone! Jon here. I have a 2007 vmax with 17,xxx miles. She ran really well until a few weeks ago. So here's what happened: my buddy rode my vmax around. (Nothing crazy, I rode next to him on his bike. He rode it just fine). So, we're in traffic for about a minute and the bike shuts off. I get it started again and it's just running very rough, almost as if the airbox came off and it started sucking in too much air(like I've read on some posts) so I get it back to my house, and it randomly starts running okay afain. Next removed the battery to take it to autozone, make sure it's okat. I was told "battery good, needs charge) so I pop the battery back in and try to jump start it with my car(car is turned off) it cranks and cranks but it doesn't turn over. I removed the carbs, they seem to be running fine, I changed the valve cover gasket because 2 sparkplugs had a dab of oil on them. I'm mechanically savy but am a bit scared of electronics. I bought a decent multimeter and am trying to look for a problem the best I can. Any suggestions?? Please help! Thank you in advance, Jon.
