    Another single seater streaker

    You can fab anything you want, and mount it anywhere you want. Just mount bearings close to the outside for the wheels, and close to the sprocket and the brake. See pic below for an example of a 4-bearing custom setup.

    Hub with internal drum brake and sprocket

    You don't need to pay the high price for parts carrying the Azusa name, and using their 3-bolt split rims. Just use cheaper aftermarket parts, and I personally prefer 4-bolt split rims. I see you have a combo split rim with 3-bolt internal combo drum brake drum and sprocket. At least it looks...

    'wittle 'wesistor (Mini Jeep)

    Don't like being a wet blanket here, but need to voice my main concern about real Jeeps. I've seen a video of several top-heavy vehicles doing an experimental rollover point test at the same speed, and the Jeep was the worst one, rolled over very easily. Not sure how that would apply to your...

    Ekkk! First Go kart!! predator 212 and series 40 driven?

    Comet Torque Converter Belts | Go Kart Drive Belts (gokartsupply.com) Same as stated above. Note that center-to-center only works when you're reading the column with your correct driven size. Comet's site is accurate for Comet belts, but you must read the c-2-c distance under the correct column...

    Gas gauge?

    Splice a barb tee into the flexible fuel line from the tank (1/4" I.D. is common), running the fuel through the main line (straight-through) of the tee. Use the branch to run a short piece of clear vinyl tubing up vertically to somewhere well above the highest part of the tank, and put a small...

    GX390 Oil seal failures

    Can you put a micrometer on the shaft and check for diameter variance all the way around where the seal rides on it? I'd say use a runout gauge and just watch the needle move as the shaft spins, but then you'd be checking variance outside of where the shaft/seal contact is made. EDIT: The...

    Free Buggy thing

    Even with working taillights, you might consider a flasher relay for a "Notice Me, Don't Hit Me" extra safety.

    Chain problems

    Even the cheapest chain will stay on under proper tensioning long enough to push it a bit. Pancho and Snaker have already mentioned the basics that should be checked first, matching chain/sprockets and find anything that's moving.

    Painting a Duramax 440?

    Duhhhhh..............Why didn't I think of abrasives? Oh yeah, not enough sleep, more than enough brain fog.

    Thoughts on clutch and shifter engagement.

    Oh, just go for it! Put paddle shifters behind the steering wheel for a real fun challenge. Ignore the shift pattern, and just make it your own.

    Slow moving vehicle sign light up? Or is it reflective? Really shows up in the pics.

    Another single seater streaker

    Washers are a great way to make spacers incrementally, but a single measured ready-made spacer simplifies everything. You don't have to guess and order what won't work, I haven't because Home Depot sells pipe. 1" pipe slides right onto 1" shafts, same with 3/4" pipe. Even the seam inside of the...

    Is this for real?

    Looks like knobbies aren't dual purpose, but would be hilarious in a K-Mart parking lot at 0600 in the morning. (Had that experience in a '99 Eldorado that would do 150mph where there's no ice, playing in the first snow in Albany, New York visiting girlfriend.) So I no longer envy y'all up there...

    How would i hook led lights to a 420

    Do you know which wire from the ignition comes from the positive side of the battery? You should branch off another wire from it to a separate switch for the lights. If the 420 wires up like the 212, it shuts down by grounding out the coil, not by running the battery power to anything in the...

    Post #18: I won't tell you your welds are bad until you post from the hospital how they broke. Post #27: Pretty work, it's good to see matching slicks all the way around.

    Carter brothers 1435 assistance needed

    What kind of condition is that axle sprocket in? Owner was using a POS Chinee spring-loaded tensioner because the motor was locked in place in the 4 bolt holes, couldn't slide to adjust the chain tension, likely skipped enough to wear out those teeth. Mount the motor on its proper mounting...

    Is this for real?

    Not being a snowbird, I know very little about driving on ice. Wait a minute. We did have an ice storm (thunderstorm rains while in single digit temp.) back in the early 90's (N. E. Florida), and I did great, even had a lot of fun. Ran heater service calls for 72 hours straight, sleeping a few...
