Those tires are not "rated" for anything. But they are the same racing tires they use on shifter karts that do actually run over 100mph. So you'll be fine.

Most racing kart tires are rated for around 110 MPH continuous. As 125cc karts run 105 regularly, that's sufficient unless you run a 250 or dual 125.

i have been enjoying your videos its getting me thinking , this can be fun.

I am estimating up 3 sizes on the main jet will get carb pretty dialed in. Then do a throttle chop on your next speed run and look at that plug. Also never underestimate what reducing some wind drag will do. Great job so far guys!

Just like the last one you should mitigate drag. At speeds over 55mph, aerodynamic drag exceeds rolling resistance and friction as the dominant source of wasted power.

@tiporari

Lenny M The precise speed varies with frontal area, rolling resistance, the coeeficient of drag, etc. It could be lower, 55 is the figure that applies to most light cars and trucks. What matters is that well within the performance envelope of that vehicle, drag will overtake friction as the loss leader. This effect is visible when Ike drives as initial acceleration is unaffected but near top speed vehicle acceleration decreases visibly even without the aid of precise timing or instrumentation. It matters for sure. That's why even race karts have some aero mitigation on them. It is essentially free performance left on the table otherwise. A 25mph yard kart? Who cares. Something exceeding 50 or 60mph? Oh yeah, you betcha.

Man this is so good. Great work guys!

Mark Carr Nice!

a little fiberglass nose cone might help a little bit too, because aerodynamics are really coming into play over 60mph.

Cool Kart guys, love the videos😁

My suggestions: -Move the axle to the rear maybe 3" and add a center bearing (that will help the "dartiness" and add weight bias to the front) -If you are changing the motor mounts, move the motor faster outboard away from the driver. -Double discs for the brakes. -Add a simple "number plate" drivers faring coming up the steering wheel shaft. That will help direct air over the drivers head and around his body/shoulders. Even better step and front down force could be obtained with a circle track type nose but one of those would last long on a "yard kart". The nose and drivers faring can be sourced cheaply on Craigslist or eBay.

Total badass love watching this video way to go ike you the MAN!!!!!!!

A turnbuckle between the rear bearing hanger and the upper motor mount bolt will fix the chain coming loose. Set the tire pressure at about 10 psi cold. The ride will be better and a little less "darty". Set the toe-in to zero and balance those tires. You can use the front wheel hubs to do all the tires. Just prop the kart up so the front axle is level, make sure the wheel bearings are free to spin and let the tire roll until it stops at it's heavy point. Then take some stick on wheel weights on the high side. Turn the wheel 90 degrees and see which way is spins to. Keep adding weight until just sets still when you let the wheel go. All of the other wheels can be done on the same hub. The gearing seems about right. Our racing 15 hp engines will do high 70's/low 80's mph with one speed. Your gears just make it a lot more fun to get there!

My review You both are very awesome to watch your intelligent, humorous, spontaneous creatative I love watching y'all ! keep it up your good at building and intertaining and thank you for sharing your treasure and pleasures

Need a center bearing on the rear axle, need paddle shifter, need road leathers, and possibly a full break kit.

*PUT IN A MINI NOS KIT!* not sure how much faster itl go but itl sound dope. also a body would help air dynamics so...

It's awesome, I love it. Yall should do a motor swap on one of the offroad karts with a motor like that but maybe semi auto

I think paddle shifters would be nice for that cart. Easier too so that you’re not taking your hand off of the steering wheel at high speeds.

More castor in the front may make it more stable. Skip the clutch after first. Wear leathers and gloves. You may wish you had. I had a KLX 250 and it would do right at 90 fully tucked in and a Ninja250 twin cylinder did about 100. I dont see the cart doing 120 with air resistance. Maybe 90 with a ton of work and some aero. Good Luck.

So close haha love you guys

legit! It sure has potential to go a lot faster. Cannot wait to see it!

Ok. Having raced karts in the past you definitely need a centre bearing on that rear axle for those speeds. It will tighten the handling and axle harmonics up dramatically. In all fairness that motor needs to go out over the right side of that from on solid mounts so you sit square in the seat. Thats also not helping your handling. I said it last video & I'll say it again - time to invest on two front brake kits. Someones gonna get hurt. No insurance, no rego & no title - you guys we ill go down so get smart and start at a track. Dont wanna see either of you dudes in cuffs. Work on safety before speed.

Agree with both, brakes especially. I'll be honest when I see them going 50 through the tree'd community it scares me even with a helmet whizzing past tree's. All it takes is for one of the janky cart spindles to say goodbye and you'll do a full body plant on a tree. Save the fast stuff for the back road (ok, technically illegal, a great many townie cops will say hey, be careful and don't hit anybodies property and go about their business.) as was said we want you guys around for a while. I think in a race though honestly, the lifan will leave the drag rail for dead till maybe the end of the track where it might freight train by and thats due to weight and overall gearing and the way the Torque converter works. Nice build though, really like this one.

Clutchless shifting doesn't put any extra wear on the transmission if done properly. Chopping the throttle to unload the transmission is similar to using the clutch. Nothing is under load so there is no damage to be done. You can do clutchless downshifts as well, although they are not as fun or as useful for going fast.

One thing that is slowing you down is air pressure, that faster you go the greater the air pressure, the more power you need to overcome it, drag coefficient.

I look forward every day to watch you guys. I really wish I lived close to you two just so I could be part of the calamity! just sayin

I had an old Margay cart with the original McCulloch 100cc 2 stroke.. Could never get it started even w/electric starter. Swapped for a 125cc dirt bike engine. Like you said huge sprocket ratio issue. Could only use 2 gears even putting a small sprocket on the axel which was hard to keep the chain on with such a short chain.. Was fun shifting, but in reality the gear ratios were way off for a 10" diameter rear tire vs a 28" dirt bike tire. Went back to the tried and true 5HP flat head modded with very thin copper head gasket and glass sanded/thinned head, shimmed exhaust spring both valves, big 15HP carb, Offset keyways advance timing. Port it big. Had some luck carefully grinding the cam shaft base circle and lengthening the lifters to achieve higher lift. Wide open screaming. They would always eventually grenade throwing the rod thru the side of the block. Used to be a near Endless supply of Briggs 5HPs at yard sales for replacement blocks. Those were the days!

_John:_ Must. Power... SHIFT!!! _Ike:_ Just gotta make a smooth shift...

Now this my friends is a beast what you need next is a beer tap shifter

this is awesome

Man that thing looks like fun. Theres nothin like rowing thru the gears and now its on a 70mph gokart

John on the forks for the ct70 use a Scotch-Brite wheel on a bench or angle grinder. it'll polish those forks really well. Use course and fine for a shine

Nice one guys. I was thinking about that jittery stearing at speed and I thought a stearing damper off a motor cycle might help out ?

That looked fast, with the right gearing and those little tweeks you mentioned, I believe 85 is more than attainable.

Hand clutch would be safer. Next if you are having brake issues overheating and can't go bigger rotor then set up multiple disk and calipers on the axle. The cart we made anything above 40 the brakes overheated and the rotor was the lowest thing to the ground so no bigger without bigger tires. So since we still had 3 gears we put 3 more on. Just put them as close as we could and put them in between the frame on the live axle. Later when we went to a taller tire we adapted the rotors off of our street bike donor we got the engine and sprockets off of and it was about the same braking power. The go kart brakes are not made for the the heat that 70 plus braking puts off. Motorcycle parts can take it. For speed shifting do a momentary button to cut the spark quick then shift. It keeps your rpm range up and less time on the clutch shift.

Would love to see you drift it in the yard! Thanks for the entertainment!!!

Bonneville salt flats. Go for go kart and mini bike land speed record and challenge red beard to see who can go faster. What a boost for your channels.

On one of the next videos yall ought to attempt to make a gearbox for a 212 just a simple 3 gear and reverse? I feel like it wouldnt be very complicated but I just dont have the mechanical know how, though I am still trying to design and piece one together

Totally awesome 😎. 👍

Pretty cool guys !!!!

clutch for taking off and stopping, clutchless shift! preload the gear lever then as soon as you back off the throttle it will slip into gear, no harm done as backing off the throttle unloads the gear box, ive done it on every motorbike i own!

Great build guys! I'd change out those light duty rear axle bearings for some HD pillow block bearings and add another pillow block bearing in the center of the axle.

73! you have some stones sir!

A spring loaded idler on the bottom of the chain would help too. My old yamaha enduro had a spring loaded delrin glide bar on it for that.

Damn that thing rips

I got one thing I would love to see y'all do. Try making a 200 CC RC. Something like that would be epic

The secret to hot starting is to gently tap the throttle wile cranking, and no clutch needed to shift once moving, lift off throttle and shift.

the shifter is supposed to be behind the steering wheel on the steering collum wich means you can bang shift it easier in a real shifter kart

Dammmn that flyby for the intro was fast

Looks like you have a lot of drag from your front end. Get that sorted and you should see over all better performance, front right camber in particular. Also tire pressure looks pretty high, run around 14 psi cold you should see better handling at high speed.

That helmet cam was very Formula 1-ish. Great sound from the exhaust on the fly-by’s too.

Runs pretty good! Hopefully I'm not getting old but that things wicked loud,it distorts the audio! Speaking of alignment, somewhere around 12:00 when you had stopped because of the chain slop Check that right front tire it's scrubbing more on the inside,it's got either too much toe out or excessive negative camber,or a little of both. Minor stuff,she's rippin!!!
