Hello All! Vstar 1300 performance problem
Hi All! This looks to be a GREAT forum.
I have a 2008 Vstar 1300 cruiser w/5k miles. Has always run great, no problems. An issue cropped up recently. It idles fine with no apparent miss but under any load, it has terrible throttle response with no power and sounds like its not running on all cylinders until the engine wakes up and almost throws me off the bike. Once it "wakes up", it has normal strong power if I stay on the throttle but as soon as I get off the throttle, it returns to the muted throttle and power. If I get back on the throttle, the process repeats itself ... no power and sounds crappy then all of a sudden, switch flipped and I'm off to the races again. It's kinda dangerous actually.
My first thought is it's a fuel system issue. Misfiring injector(s), dirty fuel filter, etc. Electrical ... misfiring coil? Any thoughts or advice is GREATLY welcomed and appreciated.
