    Just bought first kart, don't know what it is.

    The thread I linked shows exactly what I did. If you're new to steering geometry, look up some videos on Ackermann Steering. It's pretty simple once you get your head wrapped around it. Basically you want the "inside" tire to turn sharper than the "outside" tire. If you're turning left, you...

    Just bought first kart, don't know what it is.

    The front-end looks almost identical to my Yerf Dog. Mine had terrible bump steer and the turning radius was horrendous. It didn't take too much to get it to steer much, much better. https://www.diygokarts.com/community/threads/yerf-dog-bump-steer-ackermann.46590/

    Electron Cross-kart

    Maybe/kinda/sorta. If the inboard pivot point of the tie-rod is on the same plane and in-line with the pivot point of the A-arm, you won't have any bump-steer.

    Yerf Dog Bump Steer & Ackermann

    Yes, the grey bar is the pitman arm which is attached to a cross-brace mounted between the two shock mounts. The big square-headed bolt at the connection point is left "loose" and I used a jamb-nut to keep it from coming apart. It could swing fore-ad-aft very slightly (would/could bend the...

    Yerf Dog Bump Steer & Ackermann

    I picked up a worn-out Yerf Dog two-seater for my wife and kids to drive a couple of weekends ago. It "runs and drives" but it definitely needs work. One thing I can't stand about live-axle go-karts is the steering radius. None of the karts I've ridden have had Ackermann steering and all of...

    Kids Kart Width?

    These ain't city kids. My 2-year old boy already knows the weed-eater and chainsaw needs 2-stroke oil. ;) They're not going to be messing with gas for a long time, anyway (years, more than likely).

    Kids Kart Width?

    Not necessarily. But I ain't rich and 2-strokes are cheap.

    Kids Kart Width?

    I plan on using the little car basically as a seat with a dedicated/built frame beneath it. I found highly-rated 49cc 2-stroke with built-in clutch and 3:1 gear reduction. Seems like it should have plenty of power for my needs (and half the price of the Predator)...

    Kids Kart Width?

    I've got an old lawnmower frame and am considering "converting" it to a go kart for my kids (oldest is 4 currently). I don't want it to go much over 10 mph and was thinking of using a weed-eater engine for power. My question is, how wide should it be to prevent tipping? It's pretty tough to...

    212 or 420??

    This thread is a little aged but I don't see a resolution. I found a heavy-duty FNR gearbox that can take some serious horsepower. Costs an arm and a leg, though: https://rpmgearbox.com/store/

    150+ hp two seater rear axle chain driven

    On the other hand, since you're using a Snowmobile engine, you might as well take a look at what's already been done. These guys put a 130hp snowmobile engine into a Honda Odyssey FL350. You could check out what they did for the driveline and how well it works...

    150+ hp two seater rear axle chain driven

    If you want to keep the engine assembly (including CVT, etc) cross-ways you'll need a RAGB (Right-Angle Gearbox). For the type of horsepower you're talking about, you'll want an agricultural gearbox like this or similar: https://www.ever-power.net/product/rc-61-mower-gearbox/

    150+ hp two seater rear axle chain driven

    Take a look at Cracked Housing Fab's 4x4 Crosskart for inspiration. They essentially machined an adapter to bolt a sprocket to the input of a Subaru rear axle.

    150+ hp two seater rear axle chain driven

    I'd use something like a Subaru rear-end and if you want it to be "solid" I'd either make it a Lincoln Locker or install a LSD.

    I can't find your video on Youtube.
