    Can't fool me. Yamaha didn't invent that.

    Who ever said, "I think it's a little too long. How about a little off the tip?"
    No one. That's who.

    with the slip stream of air rushing past the sides of a bike, wouldn't pods #1+4 be fighting to breathe
    more than pods #2+3. Self taught just speculating not an engineer.

    Yes, sort of. The outer pair are going to be fighting against low pressure at speed because of the aistream that's induced by the motorcycle. One of the tricks that helps is to partially shroud the outer pair. This is why pods tend to work somewhat better on the XJ650 Seca than on the other models; the sidecovers partially shroud the pods.

    I can reason that the air boxes would deliver an even air pressure to all 4 carbs

    You should be able to get jets from XJ4Ever (upper right hand corner) BUT - before you do, make sure your bike is dialed in and performing successfully with a stock configuration, because there is no firm science for what size jets you need to have the bike running its best with pods. Establish that the bike performs reliably and powerful first - then modify with pods, you will have a base line as to what type of performance to expect.

    Well I’ve been a Suzuki tech for 30 years and like any engine mod inc pods just takes patience and time to set up your fuel system properly. Yes a dyno helps but I’ve been lucky to get any used or new bike run well. Even if the dyno was not available.
    Just saying.

    Clymer suggests going to slide carbs then pods to make performance increases.
    with CV carbs it is just a crap shoot just to remove an air box.
    I always wonder why most people think they are smarter than Yamaha engineers.
    I guess it is the telling someone it can not be done that sets up the challenge.

    The UK guy with the video even says he uses slides.

    if you are going to pod get good pods not the china pods

    yes you will have to rejet and rejet and rejet until you find the …. well until you are happy with the results.

    a bunch of people on the xj facebook site claim to have the proper jetting but when you try to pin them down on how well the bike runs you find they are just putting down the road to the next "coffee"shop flat road riders .
    tried all summer to get satisfactory performance out of a podded 750. ran best on flat roads and in the cold weather. did not even come close to running like my other 750 which is stock. bike with pods 85 mph max slows down on the long up hills to the point of it being a danger due to traffic around me. stock 750 just keeps going faster up hill as I twist the throttle. my 550 would leave the pod mod behind.
    I have installed an air box in it and gone back to stock jetting when spring comes I know I will not be disappointed with that ugly airbox I am thinking of putting lights in my pods so I have the cool look of pods being used as blinkers.

    feel free to pod away

    You missed that one Moe, but completely understandable :)

    I was quoting for the necro by Scott Tiplady from 2017, but it didn't actually quote it properly :/ .
