Jumping a kart off of a sand dune or similar air makes a single driver on the left side of a 2-seater tip over to the left before touching ground again, should only get air with your weight in the center. That's the only mechanical excuse that I have. Now to answer more completely and accurately...

Yes, those 3 would free-wheel just fine on those bearings that come already installed in the hubs.

Works fairly well for my center-drive position, and like power steering for the left-drive position.

I'm a believer in the remote as well...............Amazon.com: Saihisday Dual Remote Control Start Kill Switch Compatible with Chinese 55cc-125c Taotao Kazuma Roketa Sunl ATV : Automotive

By Jove, a capitol idea old shoe, jolly good! Tea and crumpets all round!...............Now being's how I ain't done got no Brit in me, ah'll jez say dat's really a smart stepper by dem GY6-making' folk.................... Seriously, I ran dirt bikes all my life, and never heard of that before...

Yes, you could do that if the bolt patterns match up from new hubs to existing wheels, and the hubs' bores fit your front spindles (front axles) (5/8"?) and the right rear axle stub (5/8"?). All 3 are free-spinning wheels on that setup, with each requiring its own 5/8" bearings (they're already...

Very true that baby-footing the gas pedal can burn up a common centrifugal clutch. Also true that letting a 10-year old have full pedal to slam down getting up to the governed max speed can also mean slamming into a fixed object (tree, building, etc.) before reacting in time. Whether it's a...

The words of a poet, who didn't know when to whoa it. Wouldn't be sneaking if the wife was peeking.

I'm picturing only 2 schools of thought there, adjustable jackshaft, or a massively strong springed tensioner for a jackshaft fixed to the motor mounting plate. Not even sure if you can properly spring tension the variable position belt if you tried. I personally want everything adjusted to my...

Anybody besides myself wear contact lenses? It's the main reason I like fenders, the dirty clothes can be washed, not "me glazzies". (Kubrick's Clockwork Orange.) Dust slung up against perf panels keeps going right on through. My Acuvue 2's are disposable, but I don't want to dispose of a pair...

I never even heard of a vacuum petcock. In all of my experience, a vacuum between the fuel cell and the intake is the last thing you want, leads to vapor lock. Gas tank caps are vented for the express purpose of not being able to draw a vacuum on the tank, stopping the gravity flow or otherwise...

If you maximize compression by choosing your billet rod to be .020" over-length with a flattop piston, and using a .010"-.012" head gasket, use a billet flywheel with rare-earth magnets and higher spark advance coupled with an advance key to reach about 36-degrees spark advance, use a hi-perf...

Only one that I'd recommend for it.................Folks call it a TC, or call it a CVT.............. That's a Torque Converter, also more accurately called a Constant Variable Transmission. In other words, common centrifugal clutches burn up, and uncommon expensive ones still can't provide the...

I should be more specific.............No regrets for doing the fun job of hotrodding the 212cc, and only a little regret for doing things in the wrong order. Never considered how heavy my "one size satisfies all" concept for a one-of-a-kind kart build (SchizoBallz) would turn out, should have...

karl, I appreciate your faith in humans. If he means it literally instead of metaphorically won't take off when sitting on it, then I have to believe he messed something up that has nothing to do with a 2nd stage upgrade kit. Failure to produce locomotion is in the drivetrain, not the...

Understood, that was just a sudden passing thought about the steady force of electric motors as they ramp up. As said, nah, forget that. I did previously look at the link of the football launcher, a little bit impressed at the geometric equations necessary to set the 2 grip wheels at their...

What are we looking at? A screenshot of a real car, or a gokart? No front brakes or suspension are visible, but could have springs hidden, we just don't know. Describe the chassis and wheels you have that you want a body for.

Any 30-weight oil would be fine, but for me, I only use $11 per quart Royal Purple Break-in Oil, even for oil changes. Only takes 1/2 quart. That makes me really upset. Maybe they were thinking you were going to have a billet flywheel............ 18# springs ungoverned can spin up a 212's rpm...

...........and that's all you need to move forward. Since you have some info on higher end OEM launchers, can you find what materials they use for the gripping wheels?..........and how much inflated and/or squeezed pressures are involved? About a heavily weighted flywheel........... I've seen a...

Call me a sissy if you want to, but with problems already showing up, I'd carry it back home and not crank it again without a wide-open intake and a fairly free exhaust. Okay, but you left out the most endangered part, a billet connecting rod with bearings. With the stronger valve springs...
