Alright maybe I?m not being specific enough this is the first kick of the engine since a full rebuild crank, bearings, ect. I install the flywheel on the crank the woodruff key is in perfect condition, I kick the 500 over and it has enough force to break my foot. The first kick would not generate a situation where the key would move in any direction. That is why I?m asking if maybe I have the timing off and is the timing the only condition to generate that strong of a kick back force? My foot was in pain for a day and I had on my alpinestar boots and used to ride an old CR500 and know all about kick back when starting.
Thanks
By the way how do I get a avatar besides the smilies ?
