I like your content , thanks . I was neighbors with a kart family and Dad kept impeccable notes for every race night and every change made ...everything . Bill (dad) paid extreme attention to tire pressure all night long . Tire pressure and tire temperature before and AFTER track time/laps . When this family showed up and you wanted to beat them , you may as well put your kart back in the trailer or just consider the laps that night as practice . Bill showed us many many times that once your kart is dialed in, minute changes in tire pressure resulted in even faster laps . This goes back to the very old saying , everything your car/kart does , it does through the tires .
Ben, when I reduce my rear tire size to gain more RPM, I don't think I'd necessarily gain more speed. As the circumference of the tire becomes less, the tire logically as a result covers less distance on the track per revolution. So, while the axle might spin faster with the smaller tire, the extra RPM will be compensated by the kart traveling a shorter distance per revolution. Ain't that right?
so while a smaller tire will cover less ground, it will positively improve acceleration correct? so smaller tires will improve acceleration nd you re-gear your kart to gain back top speed?
Can you make a video about the beginner Karter I have a go kart I found it has 23in mower tires and a medium sized sprocket it had no engine I put a gx390 on it and iv fried 2 centrifugal clutch s it's a dual seater yerf dog. Please help
If you’ve fried the clutch you’re either engaging too late or too soon on the clutch. (Usually too high of engagement causes them to wear out too fast. Also if the rear gear is to small for turning that size of tires your putting a lot of abuse on the clutch. I’m only speculating.
I use a tilted engine mount, the top of my front sprocket is pretty much in line with the top of my rear sprocket. Is it true this may create bind/loss of power out of corners? I read that the crank should ideally be the same height as the axle.
@@kart6t3_ben "The only thing about an angled mount is that it raises the engine up. Ideally the crank and the axle are the same height, the further up the crank is from the axle, the more bind you get in the chain when the kart flexes. Theoretically it robs a little power coming out of corners, or you’ll be a little more likely to throw a chain, but realistically it’s not a big deal for a KA or X30."
Changing the tire circumstances does effect the gearing. The concept, A larger tire in effect removes teeth and smaller adds to the rear gear. The gear reference is for those who can’t change it. Sorry.
We didn't have any restrictions when I started racing in the Junior class. Pussification of America continues. Do you give them participation trophies as well?
Well hell man let’s put 5 year olds out there in opens, give them kids some real adversity. Ain’t nothing pussificating about slowing things down and teaching proper racing etiquette. Quite the opposite, you have multiple generations of drivers that would rather drive through someone rather then around.
That would be track and rpm dependent so very hard to guess what you need. My only point of reference would be a 10/58 at a small 10th mile 8600 on a clone.

Great job, answered questions I did not completely understand. That's
👍

I’d say smaller tire size would reduce top end speed. Correct. So a gear change would need to happen.
Hey Ben. Is there a benefit to running a bigger or smaller driver gear if you are keeping the gear ratio close to the same?
Yes! In short a bigger driver carries more speed at the end of the straight away. A smaller driver will “launch” better off turns and restarts.
so while a smaller tire will cover less ground, it will positively improve acceleration correct? so smaller tires will improve acceleration nd you re-gear your kart to gain back top speed?
Yes that’s sounds correct.
Can you do a video on just a Burris treaded tire
I would love too unfortunately I don’t have any and it’s been a long time since I’ve run any.

Hey Ben if I go down one tooth on my driver, how many teeth do you feel I should go down on rear gear? I would like to stay around the same rpm thanks
One driver tooth is worth 3 rear. So say a 15/57 = 16/54 like that.
I thought I remembered that from one of your videos but I could not find it. Thanks you keep up with the good stuff. I really enjoy your videos

Never looked into that. Might be some truth to it? Hard to say whether the angle axle/crank actually matters or not? Interesting.

Hey Ben also rotating weight light weight axle titanium wheel studs and nuts I have a 25mm axle on a kid kart it came alive
Very true.
Hey Ben. On longer tracks do you think to much stagger will scrub off straight away speed?
Yes
Yes. The kart constantly pulling left is scrubbing speed off.
Cheating is such an ugly word. I prefer 'competitive advantages'. Haha
🤣🤣🤣
What is goin on?😂
Yup.
Man you make the day when you post a video. Don’t change a thing.
Your thumbnail is really deceptive. I came here to learn about front and rear sprockets and you basically didn’t even talk about anything of the sort.

Sprocket size for back sprocket on Gx390 for adults
That would be track and rpm dependent so very hard to guess what you need. My only point of reference would be a 10/58 at a small 10th mile 8600 on a clone.
