I recently joined another forum (old mini bikes) because that's my newest hobby. While exploring the site I found they have a b&s section upon it I discovered it is mostly flathead discussions and a few intek and animals too. I ended up reading about 10 years worth of threads but one really stuck out to me. A few of the "top guys" of the forum were claiming that the flathead flywheels were extremely dangerous above the rated rpm 3600, and any one that kept it on the engine after any modifications or removal of governor were ignorant and had no regard for the safety of their self or anyone riding it or anyone close to it. If this statement is true why wouldn't wka or any other sanction madate a billet flywheel? I have looked around in magazines and online, all I can find for sale is the billet 3 hp flywheel. Also what is the max rpm you can run it safely? Just want to get solid info before I make a reply. Thanks anyone who can help.
