I recently took a 10 day ride, in preperation I changed my oil, tranny fluid, and oiled my K&N filter. The first day I found that my bike would only start 4 ot of 5 times. It would start......but not right away. Day 2: bike wouldn't start and I was worried about draining battery, gave it some throttle and it started, but it ran rough for a couple minutes. I was on the back roads, so the next few days same thing: started most of the time, ran lousy if I had to give it fuel when starting, and started blowing black smoke from pipes. Last day make it home, but it stalled out at a light and blew a large black smoke bomb out of air intake. Any ideas???
