Is it jetted crazy rich? Is that why it’s smoking so much ? I was thinking it was a fresh rebuild , and the jetting wasn’t tuned in all the way yet, because I’m no 2 stroke expert, but thats a LOT of smoke
It must be. Granted, it’s probably bored out as well, all that fuel built up in the carb has to burn, I would understand if it’s a cold start, then it would probably be smoking like that Simply because of all that built up fuel
@@j.rodproductions9004 bikes on alcohol, you can’t leave alcohol in the carb because it eats the seals up, so after each ride it has to be run with 110 to get the alcohol out. It’s running fat, if it’s truly boosted than he’s getting a lot of air, therefore it needs to run fat
I really want to know whats the reason for the wheels to kinda jolt forward when putting it into gear you’re still pressing the cluch why does it do that?
it jolts from the friction of both the input and output clutch plates being on the same shaft, you should watch a youtube video on motorcycle clutches, i can't explain it well
Two strokes smoke exspecialy with modified pistons and ported cylinders. And it's just like putting a turbo on a snowmobile different configuration but the same type motor.Yes a turbo makes big power on a two stroke to.THATS A NICE SETUP?
Hemi is the shape of the piston head. It has an endentated hemisphere where the top of the sphere lines up with the outer ridge of the piston. where a conventional flat piston will have a flat head for simple motors of a flat endentation on the head for more complex or even interference engines with complex timing.
turbocharging a 2 stroke is completely useless and it reduces power, due to the design it will just shoot out more fuel air mixture caused by the pressure from the turbo oppositely you want a nice expansion chamber for back pressure and it will kick some major a$$
@@AllegraChickentotally different design. 2 stroke uniflow diesels aren't forced induction, they can't work without a compressor. Because the mixture comes in at the very bottom of the stroke so theres nothing to pull it in, the extra port for the "forced induction" pushes the exhaust fumes out the valves at the top which reduces pressure and pulls in the mixture at the bottom. A normal 2 stroke with a normal turbo would be straight up pointless, impossible for scavenging to work, a centrifugal superchargers or normal supercharger can work but its not worth the hassle of fixing pressure problems with cylinder filling. 2 strokes can put out 432hp/ltr without forced induction, thats literally 1hp/ltr less than the higest figure ever achieved NA in F1 with alot more money on F1's side. 130hp more than a kawasaki H2R for the same displacement. Absolutely no need for forced induction.
@@finlaymcdiarmid5832normal 2 stroke with proper turbo can and will increase power as two things are happening, you are compressing the mixture but also increasing back pressure on the exhaust, it's like putting a 2 stroke engine in higher pressure atmosphere, vgt turbos are more preferred for this than vastegate as you can control precisely how much you are choking the exhaust.
@@blackturbine the record stands at 435hp/ltr. NA for 2 strokes. People have been messing with turbo's for decades on 2 strokes and have not exceeded that with FORCED INDUCTION. tale of the tape is, doesn't work well. 2 strokes shouldn't need forced induction, ignoring heat 2 strokes should be able to get to above 800hp/ltr but in practice the most efficient 2 stroke racing engines make 435hp/ltr at 15 to 16k rpm. 4 strokes make 437hp/ltr NA at 20k rpm as seen with the F1 V10's. If 2 strokes could run as efficiently at 20k as the record breaking ones do at 15 to 16k then they would smash 4 strokes, but that isn't the case. Im not a 2 stroke GP racing engineer but its probably got something to do with heat and the limits of the 2 stroke port geometry cylinder filling etc.
This doesn't work and engine can only work at a certain pressure you can increase the pressure in the cylinder to make more power but the exhaust would not allow anymore pressure it would work the opposite you would get less power rather than more
You can’t turbo a 2 stroke without a rotary valve and a completely different cylinder design…. This is just for looks and probably much slower than naturally aspirated with proper expansion chambers.
Yep, 2 strokes make power with pressure/exhaust. A turbo runs the exhaust at around 1.2-1.8 times the boost pressure. If there were to be a boosted 2 stroke, it would need a PD supercharger, and some heavy cylinder porting to hold the intake pressures w/o blowing the boosted mixture into the exhaust.
@@-zero-3148 yes but those engines ran on diesel, had completely different cylinder designs with no boost port, and used common rail fuel system’s without a carburetor, they also weren’t designed to run with expansion chamber exhausts like the quad in the video. The only similarities the 2 stroke diesels have to these engines is that they had 2 cycles per power stroke, literally everything else is as different as it can be.
You can turbocharge two stroke. All you need to do is port exhaust so that it opens earlier than normally so that combustion pressure will leave through exhaust port and spin the turbocharger. I dont remember but either seadoo or rotax sells turbocharged two stroke.
@@dymitrnawrocki9926 it’s not that simple. If it was as easy as lowering the exhaust port timing and slapping on a turbo for huge gains then literally everybody would be doing it.
@@mr.sampson7687 even if you do it right you’re asking for your motor to blow it’s already super charging the mixture basically when it’s a 2 stroke then u turbo it will want to release the valve at the wrong time unless urs is able to be controlled which I’ve never heard of being able to
