The front (exhaust side) of the cylinder is scared. It's deep enough to see, and catch a fingernail on. I also burnt the cylinder on that side (not bad though). Could it just be bored and re-plated to stock bore? I'm looking for a cheap/good fix. I hope to switch to a Gas Gas in the fall, and don't want to sell somebody a bike with major problems, but don't want to sink too much money in it myself.
