It started for about 5 seconds yesterday and sounded good till it died, I have a 450 auto decomp cam and a 12 oz flywheel. I have a 172 pilot and a 42 main and at 500 ft elevation and around 50 degrees. I dragged it around the block with my car and it still won't start. I did try the hot start button after I couldn't get it started with the choke. I have been experimenting on the best starting techniques for this bike which I haven't had very long. I wonder if it jumped timing? Any ideas??
