I've got a flat rear tyre on my VL250. I bought a rear swingarm stand (as I don't have a center stand) to remove the rear wheel, but I am unable to use it as the exhaust is blocking the swing arm on the right side. I need to remove the exhaust. There are two bolts holding the body of it to the bikes frame, but I am unable to make them budge no matter how much might I apply to them. How would I go about removing the bolts?
