    bellmouth question, again

    how will a heat shield between the bellmouths and the battery "space" affect the air flow to the carbs. will it have an adverse effect or maybe a vortex effect with the air rushing in, hitting the shield and getting sucked in by the carbs?

    This is too vague of a question to even begin giving answers.

        If it's a heat shield, it should be on the motor side of the carbs

        As to your question, probably no effect. Bellmouths don't need much space to suck air

          Most commonly you place a heat shield between the carbs and the engine / cylinder head to keep the fuel in the carbs as cool as possible. Don't see much point in putting one as a firewall between the engine and the "electronics department"

          As for adverse effects: doubtful. The engine can only suck in so much air and the heat shield won't restrict the intake in any way that I can see.

            not so much a firewall just a bit of protection and a bit of cosmetic hardware, just dont know how bellmouths react compared to pods as far as air intake, pulsing goes

              maybe drilling some holes in the heat shield may help the air flow as when i am sat on the bike my legs cover the whole sides of the carbs so they arent really getting the air flow around them when the bike is moving forward?
