2006 VSTAR 1100 Classic
Any idea why my bike starts to misfire around 70-90 miles an hour? It sounds like it starts running on one cylinder then it goes back to two out of nowhere..?? Any advice much appreciated.
Throttle half open speeding passed 70 miles per hour, it starts misfiring and sounds like fun shots almost. Idk if it’s rpm related or load related. It rides fine, it idles excellent but in 5th gear whether I’m slowly accelerating or wide open throttle (wide open throttle happens the worst) it start misfiring bad and feels like loss of power. Then it goes back to two cylinders, it comes and goes. Always at 70+ miles per hour is when it startsIs it speed, load or rpm related? There are several topics here about carb vent causing running issues at higher speeds with the 1100.
Thank you, wow! You’re awesome. I’ll dig into this and let you know.Sounds like this could be your issue V-Star 1100 Wiki Knowledge Base - Wind Bogging Engine - Carb Vent Hose

Been looking up about a problem I've been noticing, and looks like I might need to try and tie up the carb vent tube in a different way. The bike runs great but kind of surges or feels like it's missing at times once I'm up to highway speeds. How exactly is everyone moving them to possibly get...www.starbikeforums.com
