So I went out and bought a 2005 Yamaha v Star 650 classic I started turning it into a bobber build and it sat for a while because I got caught up with life so I ended up needing a carb clean I took it to Libby's motor world in New Haven Connecticut and when I got it back I had so many problems! I suppose the first thing I should mention was that when I had it cleaned I also had them jetted out because I gave them slip-ons to put on the exhaust but they said that they didn't fit so they just didn't do it and yet it was still jetted out The issue that I have with the bike well the best way that I could describe it would be that it feels like it's running out of gas and it's definitely not could that be a back pressure issue as in I need to do something with my exhaust? I did drill into the end of my exhaust for decent size holes which helped it stop sounding like a scooter but didn't solve the problem... It happened kind of recently so I was hoping it was bad gas but I drained it and refilled it with known clean gas and still same issue it really bogs and sputters but only when I roll on the throttle starts to fine choke works fine idles fine it's not gear specific it's not specific to any amount of throttle... Any ideas please help??!!!
