man i love the exposed air intakes on the carb. i remember how cool even my rotax kart would sound with the airbox off. this must sound insane. i've always wanted 2 get into one of these.i'm driving fbmw now though, good stuff.

I just noticed you have a Stockman Kart, i used to race against him in the early 1990's out at Amaroo....he was the man to beat back in those days. I was flagging at Amaroo one time and 2 dogs jumped the fence and ran onto the track infront of him...i had to black flag the race, im sure he would remember that day.

im pretty mechanically inclined, ive done plenty of work on cars, still do. I understand how fuel injection works 100%, but what i have yet to figure out is what the little slide thing on these type of small engine carbs is for, i know theres a throttle plate after the slide, but the part you see in this video in the carb that moves up and down. If that like a sort of fuel metering device? So as more air moves through the carb, it opens the jet up more or something?

Oh and the engine didnt produce power @ 6:27 and forth, as he opened it up,he saw that it wasnt pulling at all and so he whent on the side and closed the throttle again. Offcourse if we dont hear out from NEC racing on what actually happened all we can do is speculate.

Super cool view looking into the carbs! Is that a dial-a-jet setup? It sounded like it started to tighten up a few seconds before it finally stuck.

yep, and as i suspected the engine seized as he was off throttle. The fuel provides the two stroke engines with their required oil. When you cut off the fuel you cut off the oil as well. Now closing the fuel/oil mix on a motor running that high on rpm's is really hard on the internals. From what i saw/heard when the cart was running WOT it did not have any problem, so yea i cant say that the open carbs where the fault on this seizure.

@Genetics7 i figured out what it is, its the main jet (atleast im pretty sure anyway) and that piece moving up and down is how it puts the right amount of fuel in according to how much air is flowing through the carb.

just curious as to what caused the seize? what brand oil do these guys use? these karts are like comparing a ferarri to a mazda miyata for what im trying to acheive. i bought one of those bicycle engine kits off ebay but have been modifying the cylinder, piston and head a bit and i want to use a high end oil to help ensure it wont sieze up as well. what would you recommend? thanks for your time.

+G DK ive seen 22,000ks on race scooters and gp bikes. 2 strokes can rev high if tuned with a good pipe but all that makes is hp no tourqe. if you want torque get a good low end pipe like a chamber pipe or lowend tuned pipe. I personaly have hit 13,000 rpm on my acooter and another guy with the same block but an polini bore hit 17,000 and hes a armature like me. its all about the bore, crank, pipe. mostly money and skill.

Was it the left piston that went? Appeared your carbs were slightly out of sync, which will cause problems at below half throttle. The less those slides are closed, the more lubrication the engine will get. It's important to keep on the throttle with a two stroke, even if its injected.

Please, Two stroke motors overheat quicker because of the jetting not because of being a two-stroke. The reason the motor seized is because the way honda changed the construction of certain pieces of the motor. Now, it needs a different fuel jet so it can run at the proper temperatures. This "Stuck" because of the wrong jetting. *A "Jet" is the thing that squirts fuel into the carburetor intake. Then it also could have been from the wrong Fuel/oil ratio, this is racing, Shit happens.

Looks fun. I noticed that you used the engine to slow you down, forcing the engine to maintin high rev's with a closed throttle on a 2-stroke that is not oil injected is something that is unhealthy for 2-stroke engines since the the oil which is in the fuel is what lubricates the engine is not flowing enough to lubricate the engine while throttle is shut and engine is at high rev's. Just thought I'd mention that.

The engine siezed because the carburators are uncovered, at the speeds these karts race there is so much air tubulence that you can litterally see the fuel being sucked out of the carbs. it simply leaned out

@avmaviator and whats your theory then...? and it sure takes fuel and oil but at way reduced quantities... Thats why when they set up the carbs according to the person driving it. Yours would end up like that probably if you revved it like him and kept downshifting trying to be constantly in the power band but i have a strong feeling that you are caring more for your motor, not ragging it constantly...

Marek Sumguy Power. The engines on the karts are rebuilt so often, depends on the manufacturer but it is measured in hours. These intakes are rear facing. So the low risk is not a big price to pay with frequent rebuilds for about 1hp difference. On a small engine like that 1hp is about 1% of the power so definitely worth it if you want maximum performance. Some racers use filters some don’t. But the answer to your question is power and performance. This is racing, performance and safety are the only reasons. Edit: btw the lack of filters likely had nothing to do with the seizure.

@anothercbrowner Thats not correct. The engine started loosing power around 6:32-33 then it finally locked up. His plates were still open at that time (plus sound delay too) Your explanation for this seize has some logic in it, but it is wrong. Even when the carb is "closed" it is still getting fuel, and oil. If that was the case, there would be a LOT of dead engines out there, mine included...
