Hi everybody! My friend just bought '00 WR400F from Japan. We have a hell of a time firing it with the kickstart. Compression seems to be so high, we actually have to jump on the kickstart. As result, we broke the kick shaft I know this might been an old issue, as we all now have 450's but does anyone had the similar problem with WR400F those days and how to fix the compression for easier start??? We all run on 95 octane gas here! Please reply if there were any solutions developed!
