Hi guys just have a couple questions about my Bearkat Twister. First were would I look for the serial# of the bike or do they all have one? I can't seem to find it.And the engine size I can't find a tag or a number on the engine. It is an aluminum block Briggs and Stratton embossed B/S flywheel cover, eight head bolts, and it is a flathead. Is it a 6 horse? I would greatly appreciate any help.
