Dr. Hugo G. Hackenbush This is my first engine failure since 2005 😝 The issue here was cold pinch due to the missing thermostat and it turns out these cylinders was never intended to be tuned, for tuning they use a different cylinder/piston clarance (I have matched that now)

How many hours/kilometers? If not a lot I think the likely cause is a wrong mix. Also be careful with the oil quality... I tested ipone and motul : piston was perfect at replacement step with motul, but with ipone oil the piston was dirt (with same running hours, kind of roads). Good luck!!
@@sashabanchi8679it is related but not that big of an impact. if you have more oil in it, it's less gas compared to air. So it definetly makes a difference wheter you run 6% or 2% oil mixture with the same carb setting.
I seized my KMX125 30 years ago the same way. I was running full throttle on the highway, a car pulled over just in front of me, I cut the throttle and applied the brakes, and when I opened the throttle again, the engine seized. What happened ? When cutting throttle, no oil is pumped into the engine anymore. Therefore seizure. It's as easy as that. Now I've learned to drive a bike and always keep a minimum of tension in the throttle cable, and also I'm driving a 4 stroke 4 cylinder 1000cc bike now. Full throttle on the highway is not possible anymore.
This exactly happend to my moped after i put on a high rpm exhaust (vocca warrior) om My 75cc I went full throtle and went about 120 km/h and it just died
Great content, keep it coming! Please buy an EGT and make sure to use it while riding, that way you´ll know when to stop pushing he bike before something happens.
wow normally when I blow up a twostroke it's the piston skirt cracking off and embedding metal into the head. but this was the cilender plating chipping off first maybe its a BRC issue.
Yeah, I heard from others who seized too. U can't go full throttle on these. After 6800rpm the power signs out and all you do is superheat the piston and the engine "cold pinch seizure"
@@celestinschermann5927 il est au mélange et sûrement une mauvaise huile ou alors il n'as pas assez mélangé car il a serré quand le moteur etait en charge a fond
It did "cold pinch", but not because dropping in temperature. To quote BRC: "our kit was never design to produce power over 6800rpm" I know NOW that if you ride this engine over 6800rpm it drops fast in power and it causes the piston to heat up fast insted. ALOT of ppl have seized these, I was just filming when I did. IMO this is a prototype engine that should never have been sold to the public.
Yo hi, schade, dass ich dir bei deinem Projekt voll und ganz unterstütze, auch wenn dein Motor kaputt gegangen ist ... Ich bin ein Franzose, der dich zufällig mit deinem 500 BRC auf Instagram entdeckt hat und ich habe gerade deinen UA-cam-Kanal entdeckt. Zwinge dich.
I suggest you to get a proper carburator, i may be wrong, but newer ktm's Has the 36 carb. Maybe you should get a 38 or even a 39 with some proper jetting. The 500cc draws a lot more air volume. Or even better a lectron carb, but not just plug and play one, one that is properly jetted for supermoto, wideopen cycles.
Didn't know that. 😬 in any case those "huge" bores in a super moto use will be surely less fragile if ran on a little bit richer mixture, surely be better leaving the "lean" spot on mixture for 125cc's
Ron Shteiner I tried both lectron 38 H series and a lectron 40mm. But it seemed like i had to choose between easy start or power 😂 The middle thing was just "meh" fuel range was good tho 😝 atm I have a 36keihin bored to 39,3mm thats 100% as big as my reed will allow as for size. If you just messure the diameter x 3,14 on carb and backwards messuring it on the intake/ reed opening. BUT In Adam Miller is working on his BRC 500 now, so I'm pretty sure he will come up with the PERFECT carbsetup 😝
Ron Shteiner There will ba a wait intil i get the cylinder back atleast, but weight reduction is still going 👌 Reached 99,53 KG today👌 jetting was to BRC spec + some more, but I'm thinking that I'm gonna go WAY up on the mainjet, and jet downwards til it does not drown next time😂 to be 100% sure😂

Never give up 💪💪💪
More mix!!!!! 4sure such a gripped cylinder in 2strokes are about pour gasoline it was running lean
Oil mixture is not related to running an engine lean or rich.
I’m not talking about fuel/oil
I’m talking about gasoline/ air

Never use engine brake on two stroke
it was not the cause
@@tsx2582 lol no kidding! 🤔 That would be the same as not revving the engine up and letting it idle back down...
I forgot to say, *I agree with you!*
Serrage au 4 coin dilatation piston excessif ( trop d’avance à l’allumage ou piston côte trop grande )
Manu Texier 4 coins=surchauffe en général
Oui mais il est important d’en s’avoir la cause !
That's not the fault of BRC. Whew! I'd talk to the shop on the ring spec they mic'd them at.

Im very sure, you were that guy on instagram spamming under every 300cc picture: "Buy a BRC 500 kit, its the best"
D'r Spätzlescowboy Still is 🤣 this is me pushing the engine WAY longer than it was built for😝 I rode the stock BRC all last season
@@gnagsaar_ it is better but waaaay less reliable
This exactly happend to my moped after i put on a high rpm exhaust (vocca warrior) om My 75cc I went full throtle and went about 120 km/h and it just died

Some break-in?
Great content, keep it coming! Please buy an EGT and make sure to use it while riding, that way you´ll know when to stop pushing he bike before something happens.
Main jet or piston ring end gap was incorrect. Possibly oil mix ratio but surly you got that right with a 8-10k engine?
Impatiently waiting..... good luck bro

Can’t trust these Canadian companies anymore. My panthera electric start kit is garbage I have so many issues with it
yeah 😒 sorry to hear that 😬 if it helps, the electric starters on brc lasts like 10hr of riding 😂 and with only re-starting an already hot engine😝
Ouch... Bad image for brc
2T depends more of the driver and the guy who mount the motor
Two strokes just are like this if everything isn't correct.
Please post some street ride videos of this bike, I'm not seeing anything. Thanks
Charles S later for sure 👌
Lol like it how you have music to cover the sound off your bike fucking up because you haven’t used a big enough mix
Kondolera. Men godt du ikkje gir deg på an
AndyLonn Lere kanskje nåke av da 😝 neida, va uforsiktig
Cool!
maybe you drive without enough oil mix
U should have at least 4% mix in that machine
That top ring wasn't right at all. Mic and check it. Looks like it wasn't slipping, but scuffing to scraping the walls as if it were a 4T.
Tous sec au démontage.....

Mr Golden le moteur à pas été bien lubrifié donc pas d’huile donc serrage

The engine fell below operating temperature is what I'm guessing. Cold seizure for sure

ah another youtube video i leave muted the entire time. great.
Wdym "sorry headphone users"? More like bless the headphone users🥵
Would look into the cause before just reassembling once new piston and plating.
Tristan Tee Yeah ofcorse, gonna do counter messures to EVERYTHING that could have been wrong 😝
Well, at least you got $500.
