Yeah I only left my right ear bud in. No music. Perfect. Lol

I had to adjust the audio balance so I didn't have to listen to that annoying music from the 80's or 90's. I prefer videos like this with no music.

Thanks for sharing

I had a 1983 Yamaha YZ125 dirt bike that had worn crank seals. One day, the engine RPM suddenly increased to a very high level un-commanded and I had to press down on the kill switch for several seconds before it finally died out. After that, it never started again until I sold it to somebody who went through the whole engine with a fine tooth comb and replacing all worn parts.

@@vigorousboredom7016 yes..Lean out can cause piston seizures crank rod bearing fail from no oil and not lean mixture.

Glad you liked it

Good choice!

this is the first video closest to the truth of the reason a 4 stroke will never make as much horsepower as a 2 stroke of the same displacement ! now watch the video again and again and listen as its told pressure is forced higher than the incoming air trapped by the reed valve as the piston is making the compression in the crank case 1st that is much higher than the air than enters the carburetor ...we call this condition supercharging by no other name .and when he stress the fact that it is a sound wave that blocks the supercharged air from escaping the exhaust port as the piston now traps the supercharged intake air/fuel and compresses this mixture the 2nd time into the combustion chamber right before the spare plug explode the mixture with no telling how much more force than a 4 stroke of the same displacement but i will say that Yamaha knows along with KTM , Husqvarna and GasGas who has their MC 125 two stroke making 40 horsepower that is roughly 20 horsepower that Honda's pro CRF150 R motocross racer that on a good day barely makes a claimed 23 horsepower while the GasGas is in the 1st turn while the Honda is still clearing the gate after a little cuttie turns the 5 sec board sideways skipping off the track wearing a skirt and top she out grew years ago

Once upon a time that may have been true about 2 strokes having more power than a 4 stroke of the same displacement but not anymore. A yamaha 250 f can make more hp than a yz 250 . The reason is the,compression ratio. Follow the 2 cycle on a complete cycle again and observe that as the piston rises it doesnt start true,compression until the piston completeley closes,all the intake , transfer and exhaust ports which is about halfway of the upward intake , exhaust then compression stroke, AND,the power stroke,has the same situation , it only has a,2/3 or so true,power stroke before a giant hole opens up and bleeds off any expanding gases that could act upon the piston face if it didnt. Altho the 2 stroke has primary compression in the crankcase area under the piston and has a power stroke every time at TDC or twice as many as a four stroke it doesnt have the efficiency of a four stroke in the Carnot cycle or PVT ( pressure - volume - temp relationship which has a total duration ( some can have more than 180 degrees,of compression or power but to some extant ot is 180 on each . A higher compression ratio is a more efficient engine and doesnt waste the fuel as much and also has a better lubrication system than the total loss of burning it . However where the 2 stroke shines over the 4 stroke is power to weight. Very light, simple and cost effecrive do to simplicity and less parts to machine.

@@waynegarfield6607 why are you here ? your total ignorance of engines is pathetic ..i am an apprentice of the late Hideo "Pops Yoshimura the most famous tuner of all times knowig more than you anyone else ..as now i have all his knowledge and YOU DONT

@@waynegarfield6607 what you said is impossible simply because 4 stroke dirt bikes are not supercharged but 2 stroke dirt bikes are internally supercharged by the double action of their pistons that was said to be true by Hideo "Pops" Yoshimura , the man who invented honda's very 1st 2 stroke called the Elsinore ..ever heard of one ? they are the bikes that make that Braaaaping sound when your being passed and yelled at "get outa myway bitch"

Awesome, thank you!

It'll be fine back the timing of some if it starts pinging

@@danielfrazier840 Thanks for the replay, but I defo should have bought a suitable piston, I've damaged the Nikasil plating on the cylinder and it will cost me plenty to put right.

Listen to it in stereo the music is mainly on the left channel the dialog is in the right channel.
