I think it runs a bit rich, mine isn't variable like yours..... If it was, I'd mess with it constantly! I like them, works really good when it's hot, I can hardly tell the engine is running, and having the true dual exhaust helps with heat as well. I don't know if you e got stock exhaust with a catalytic converter or not, but if so...... It'll cut down the heat.
