    KZ400 Update

    How I bought it:



    Update:













    The filter for my 2 into 1 is retardedly big, will switch to velocity stacks. Also I plan on putting some type of rear fender to ensure im not spraying all over the place. I have rearsets that are not pictured either. Still lots to do

    I come here for technical questions all the time so i felt i should share (and take the necessary heat that builds get )

    Why did you put a 2 into 1 intake? A close up of it would be nice.

    I have the stock carbs and such so it's not like this is my only option. I would prefer constructive criticism though

    Okay, how about "I would prepare a reasoned defense of your methods and rationale for that mod, because what you are doing appears at first glance to be so misguided and amateurish that numerous observers are likely to mock it without doing you the courtesy of undertaking any further examination."

    Better?

    is that a stock 1.6x18 front rim or has it been relaced to something else?

    Constructive comment: You went from straight into the head to an intake with 3x90 degree turns for the left cylinder, 1x180 degree + 1x90 degree for the right. While I appreciate use of copper, and reuse of plumbing fittings, this can only serve to decrease performance. Plus the copper will soak up engine heat like nobody's business.

    Buell X1
    Honda S90 (box of parts)
    Honda CB750C (runs)
    The Others (mostly rolling wounded)

    On the intake system, I applaud you for stepping outside the box. I'd actually like to hear about how it turns out. The design can always be refined with better materials down the road. At the very least, it's a quick and easy way to see if it works out the way you want. I've built a few intake systems for automotive applications, (White Knuckle Ride) and the design, although a little "turny" will work. Not everything has to be a straight shot into the port. About heat soak, since it uses stock style "boots" to connect to the head, I wouldn't think it would be as bad as any other type where the joint is metal to metal

    I think a single carb intake has some merit for a machine with a certain purpose in mind, where all out top end performance isn't the goal. Simplified throttle cabling, simplified tuning with increased signal strength at the carb (no balancing, single jet change, etc).

    At the very best, it would be an awesome design for a turbo charged deal!

    Its ridiculous. Calling it "outside the box" is just plain silly. Its bad. You don't have to be a genius to know that nothing positive was achived and that the performance will suck. You can use that kind of engineering solutions on a water pump. Not on a motorcycle - especially on one that has low bars and is pretending to be an improvement.

    And even if it had turbo charger the design is horribe, its not like pressuricing intake wouldn't mean efficiency and charge losses in a badly flowing design.

    The intake has achived:
    airfilter placed where knee would be
    less power
    somewhat likely uneven intake charge between left and right cylinders
    looks that say all of the above
