Just bought my first motorcycle a month ago, 2007 Vulcan 500 with 4,000 miles. For the first couple weeks it ran fine. Then it started stalling and/or hesitating badly the first time I gave it a decent amount of throttle from a stop after warming up. Usually I'd go to pull out of my driveway and it would stall or sputter for a couple seconds before it would accelerate. After it would run fine until it sat for a couple hours and cooled down. Did a search here and on other sites and found this is pretty common in cool weather (been 40-55 degrees the last few weeks), and followed some recommendations to leave the choke half on for the first mile or so. This got rid of the problem for a couple weeks, but now the last few days it's been stalling even with the choke half on. Then today it hit the gas reserve with only 65 miles since I filled it. Most of my driving has been short trips of maybe 5 miles, usually with it warming up for at least 2-3 minutes first, and I've been driving pretty aggressively, taking it to 30MPH in first, 50MPH in second, etc., could this be why the gas mileage is so low, or should I get it checked out?
I put some seafoam in the gas this afternoon then took it for a ride, now it was running rough, poor acceleration, hesitating from stops, etc., I'm hoping it's the seafoam working, guess I'll have to to see if it improves. The dealership I got it from said they cleaned the carbs when it was traded in, but who knows.
Also, there's now a buzzing noise coming from the speedometer. At first it was just when I was warming it up with the choke on, but now I can hear it when I let off the throttle while riding. I guess it could be the vibrations from the engine running rough, but I can wiggle the speedometer around a little bit in it's housing. Is this normal, or is there a way to tighten it?
