Hey guys, so I had the day off from work today and decided to go see a movie. The ride there was nothing out of the ordinary, just enjoying the bike and the new yosh exhaust I put on. So, after the movie I come out and get on my bike and start riding. I let it warm up, went a mile or two and had to get on the freeway. Usually when I merge, I accelerate up to about 85 mph and let off to flow with traffic. To be honest, I pay more attention to the tach and the sound of the bike... anyway so I had to merge quickly and that's no problem, especially with the new exhaust the bike feels even more responsive. So I merge and the revs sound normal but my body senses something off. I look down and I'm at barley above 60 mph. I then sense immediately the bike isn't picking up or pulling like it usually does...as another forum member once said and forgive me I forget where but "it's like the revs aren't in match with increased speed" like usually the bike picks up revs and speed somewhat in sync. It was like the bike was SOUNDING like it was was accelerating, but wasn't doing it how it should. When there was a break in traffic I tested opening up the trottle. The bike usually pulls well even from.5k up even in 6th gear and gets to 102-105 pretty quickly relatively speaking and then the last 10 or so mph are slow. This time the bike almost bogged when I opened it.wide in 5th, got to 60mph and way more slowly then it should got to 85 mph and just hit a wall... I was thinking what the help is going on?, my first thought was I accidentally hit my area p box and set it to the wrong map. So I rushed home and no it's still set just as it should be. Then I thought maybe because I'm running my yosh with out the baffle maybe it's there's not enough backpressure, but that makes no sense because I've had it for 2 weeks and over 100 miles running great. I'm out of ideas and really upset. I'm going to put the baffle in now and see if that helps. How the heck can I turn the bike off, come back two hours later and it's behaving so much differently? And no the bike wasn't hit or damaged, I checked everything.no warning lights either. This doesn't make any sense.... Thanks for any help guys. I'm hoping it goes away randomly just like it came, but that's not usually how it works..
