The 2x4s are oriented the wrong way, they should be turned 90 degrees to take the stress of your weight bouncing around. Right now your frame has the strength of a sheet of plywood and it's gonna fold. With any structurally safe kart, you should be able to stand in the drivers seat, and jump...

Another take away from this might be to use the right size fuel line with clamps.

If anyone comes across this thread, these rims ended up working. It does not say so, but they are dual pattern , 3x2.5in with 1/4 holes, and 3x58mm with 8mm holes. https://www.bmikarts.com/6-VanK-Non-Machined-Classic-Kart-Quarter-Midget-Wheel--Black-Powder-Painted_p_38333.html

nuthin but me hair

Thats thats very helpful, thanks. but a bit late I already ordered new rims.

Also looking for rear rims. All I see in 6in are 3 on 2.5in with 1/4in studs. My hubs are 3 x 56mm on 8mm studs, 8in wide.

I will send it for dale Mainly I am looking for the LH seat bracket that someone welded in a replacement for. And the 40mm tubular axle needs new bearings.

Picked up this toy. Was looking for some pictures of a stock frame , as there are a few things that were cut/ modded. Also interested in an approximate build date. Thanks.

Did it start before the carb clean+ oil change?

looks minty

Because the engineers at tecumseh said so. Its says right on the dipstick to run sae30. For winter use , 5w30 is recommended, and if you don't have that 10w30 is an acceptable substitute, again for cold weather use. It says in their service update book, and the repair manual that running multi...

I must ask, what is the advantage of a bored stock carb over an appropriately sized slide carb, that lets just say flows the exact same cfm? As in performance, not just being able to bolt the stock airbox back on the engine. Yeah totally , but why does the smaller carb being stock type matter?

Sounds like blowby pushed oil through the crankcase breather back into the air intake. If you run them above governed speeds, like adjust or remove it, it will happen. Or the motor is just worn and the cylinder has too much blowby. Instead of running the breather hose back to the intake, you...

Yeah Ive done it, but it's not going to be worth it 98% of the time. Especially when you can pick up a new predator for cheap, just grabbed one this weekend for $100. But here is how I mounted mine, just angle iron and some scraps.

Chains don't slip :thumbsup:

Yeah it prevents the torque converter from going into overdrive. Depending on vehicle weight, gear ratio, and motor mods it may be beneficial to install it, especially if your trying to push alot more rpm then the converter was intended for. Generally on a stock engine, the shim will only limit...

Thanks pearl, unfortunately I had to retire the loop. It just kept cracking, after the 3rd patch job I was done with it Anyway I ordered another mech caliper, this time an amazon special. Im going to try it with a plain mild steel rotor on the 459cc minibike. Should be a good test

270cc was not doing it, got me a 459cc. Might get brakes next

I think it was determined that they arnt good for drag racing. A traditional racing clutch is more repeatable and gooder. And not really suited for racing , its really only good for clutch dumps/ fun riding. And for that the price is just too high. If it were half the price and available in...

This was not the direction I thought this thread would go lol. I was shopping for the cheapest plain steel 1in rotor I could find, and nothing was below $35. I was going to place an order with bmi karts anyways, and they had the billet 1in hub and the drilled rotor , $30 total. Cost less...
