Well I tried putting a torch to it and still wouldn't budge. However, I tried a trick I found on You Tube and thought I would pass it along. I took the spark plug outta #1 cylinder (doesn't matter which you use). Stuck my finger in and felt when the cylinder reached the top. Then spun the flywheel to bring the piston back down. Then I fed some soft nylon rope i had lying around into the cylinder through that hole (took about 10 feet although I'm sure it would work with less). Spun the flywheel again and the rope stopped the piston. Put the wrench on the flywheel bolt (the handle about 45 degrees basically aiming to the headlight, grabbed the handlebars, and put one foot on the wrench handle. Viola! I was kinda hesitant to try this but it worked like a charm.
