Moin people, I’m completely new here and would have a problem there. I had a Yamaha XVS650 97’Bj with an open exhaust and a different air. So now to the problem, the machine wanted to go for a walk after about 2Km drive I had to overtake a car of course full gas and Bam it hit a misignition no idea why, after that nothing at all as it has to run the XVS does not take a high gas bangs on only give misignitions while driving, drains off. Only mi t fully drawn choke works with ach and krach but the more gas I want to give the more it starts to stutter and choke. In idle it runs quite ok, just normal. Spark plugs were changed since the old ones were already black and partly no more dry. I am in despair help me ! =( Thanks in advance people =)
