    I changed up the gearing slightly. I have the 48T paired with a 13T for a 3.7 ratio. There is no noticeable difference in torque from the 10T I started with. It's still pretty good and kicks up some gravel. The speed calculator says top speed at 4500 RPM will be 58 mph. My GPS clocked me at...

    Sprocket, Clutch, Chain Advice

    I have a Polaris ATV. It's belt driven and the belt is enclosed in a water tight compartment. I got water in it once, and it was completely useless until I had it dry again. I was thinking this must be a problem for all the guys using the torque converters on their trail buggy. I'm assuming most...

    Gas vs GassLess welding

    If you have the option of using gas on your machine, that's great to have!!! Not sure if you know this or not...... If your machine is capable of using gas, it may be wired so that the gun is positive, and the ground clamp will be negative, as it should be for using gas. Flux core wire (gassles)...

    I had to adjust the length of the rods, but it did not effect the radius. Lock to lock is 10 to 2. (clock face) I can do a u turn on the road using both lanes but not touching either shoulder. That's good enough for me.

    Frame design

    I started out this kart project with visions of perfection and performance. Now I'm cutting and hacking and Jerry rigging parts together!!! I'm going to chalk this build up to "a learning experience" The next one can be perfect. Lol.

    So I fixed my steering, a little bit. I extended the arms on my spindles from 2.5" to 5" long. The next issue with steering may be the steering wheel. I think I went a bit heavy on castor, and I don't have the leverage I need at the steering wheel. It's a 10" wheel. It's a lot more manageable...

    Gas vs GassLess welding

    Gas shield is preferable. A wire wheel on a 4.5" grinder makes slag removal a breeze.

    First "on the Pavement" run today. Steering is very stiff and extremely touchy!! Brakes are just a vague suggestion of stopping. Throttle ended up being hand control for now, but actually works pretty good. I started out with 4.8:1. Loads of torque. Spins and kicks gravel. I have no idea of...

    Throttle set up

    Well I have just about had enough with this throttle issue!!! Made a couple silly mistakes due to trial and error. I believe the governor spring is causing problems. It takes a fair amount of force to get the lever to the full speed position, then it won't return to idle on its own. I needed to...

    No Weld Frame

    If you are drilling hoes in thin wall tubing, or any thin steel, a step drill is a really good item to have. It doesn't grab and twist Luke a normal twist bit.

    1’ clutch 420 chain tooth sizes?

    You very well might be right! I havnt done enough hands on expirementing to say for certain. Calculations for speed with ratios alone is one thing, having the HP to make it happen is another. I can't imagine 4 teeth, or .32" of leverage, taking a cart from " not working" to "works awesome"...

    1’ clutch 420 chain tooth sizes?

    I'm curious how much of a difference the 10T will make in place of the 14T. Post your results!! There is less than. 3/8" difference on the radius of the sprocket. Just wondering how much if a leverage advantage that will be.

    What engine are you running,? Wheel size? Approximate weight of cart & driver?

    Welded hub sprockets

    Well I went with the welding option. Lathe would of been better, but it's not as readily available as welding for me.

    Frame design

    A reliable throttle control is proving to be a bit of a pain. Need to pick up just the right spring. Still fiddling with that. Getting my brake set up right is a bit of a tedious operation too. When installing the chain I thought I had lucked out on my sprocket spacing, fit so nice. Under power...

    A little more work tonight with a bit of success and a few lessons. I got a functioning drive in place. Belt installed and chain in place. Did a test run on Jack stands.

    Hmmmmm. Good point on the chain link issue.

    Welded hub sprockets

    Ha, good idea! I was just going to offset the sprocket on the hub to allow chain clearance before welding it. Turning it down on the lathe is way better.

    Frame design

    Well I'm thinking I'm going to have enough HP to always reach the 3600 RPM, so I'm guessing I might get into using the 18T on the driver. Anyways, that's why I picked up a range of sprockets. I'll play around with the ratios, see how high, and how low I can go and still have a functional kart...
