Middels kina kvalitet. Holder greit til litt småkjøring og slikt. Over tid løsna eikene på bakhjulet, bakdemperen knakk og lyddemperen til potta falt av. Renset forgasseren ett par ganger, ellers har den fungert bra

Haha thats very relatable. I would say its on of the best books to read on this subject. You are also completely right. Start small :)

Bugger off

@@Roopak-Mohan lols ffs thats my phrase haha

Hei, stemmer det. Har den fortsatt, men usikker på om jeg får laget noe ny video. Må eventuelt bli etter vinteren da :-)

Ja, men denne sykkelen bremser bra på motoren og

Forstår ikke spørsmålet

@Specerx! it crash always

@@Roope.Willstrom You are the problem if you crash, not the bikes fault

@@amsaero657 U dont know..

@@Roope.Willstrom I know failure can make you crash, but most of the times it’s the rider

Your MOST important tool is your brain. Get it filled with as much information about two stroke engines, then form your own opinion because everybody's idea is slightly different. Read the Jennings book and the Bell book for starters. All online somewhere. If you don't have money for a grinder, just use some regular files. I did when I ported my DT175E cylinder. To reach the tight spots, just bend the file. Use a hot flame on the area you want to bend. Just use enough heat so that it won't snap. Practice on an old file first. I found an slight S-bend worked quite well. Make sure your file is sharp so that it cuts as fast as possible. Use your other hand to apply downward force on the file so that when you pull with you main hand, the cut is effective. Only cut one way, else you will dull your files. This takes a little longer BUT you won't need to remove a lot of material. I think I removed about 1.5 mm off the top of the exhaust port on my bike and there was a definite increase in the way the engine would deliver its power. My brother had a newer DT175 (1981 model) that was standard. We did a side by side drag race. I could run the engine speed higher in each gear and this allowed me to re-pass my brother's bike who had slowly pulled away from me. This may have been due to some loss of power or my engine was just older. Don't omit the slight chamfer the piston rings need so that they do not get trapped. Some books do not explain this very well. The rings need a shallow or small angle to allow the cylinder side to gently push the ring back into the piston as it passes the top of the port. The size of the chamfer is determined by how far out the ring protrudes from the piston during the time the ports are open. If the chamfer is not done or is done wrong, you could be finding broken rings in your exhaust and no compression. Been there, done that. Don't only port your engine. Use a slightly larger carburetor or get it bored out. Raise the compression ratio a bit. Most regular fuels can handle a little higher compression before knocking starts. If you try methanol, you can raise the CR quite a lot - and this means a lot more power but shorter engine life. Any change for more speed and power needs more fuel. Get ready to buy larger jets or whole jet sets if you are doing methanol.

Greit å være litt forsiktig i starten ja. Vi fulgte hvertfall produsentens spesifikasjoner

Have tried it :)

Fungerte bra, men kvaliteten var dårlig. 2. Giret hopper til nøytral hele tiden og det meste ramler av og knekker. Kan skyldes måten jeg kjører på og da....

@@DidrikNa Tack! :)

@@DidrikNa Skulle du rekommendera att köpa denna?

Yes, they sell mt parts different places in norway

As I far as I remember, it was stock

Raise it too much and the engine will ping.

Reworking the swish band std head was pants.

@@ronito1271 you will FEEL the power...

@@Ni9kye the degree???

@@jensentidurmakan6404 follow the shape of the piston crown, the squish gap should be as close as can be without piston hitting head at high rpm. Remember the rod will stretch at high rpm. a gap of 0.7 mm should be good. You will have to take a load of material off the head to do this work. Somthing in the order of 5mm. And have to shape the dome in the center. You will find that the long bolt fixing the head to the frame will no longer line up! so you will also have to grind out the fixing hole in the frame to compensate. If you have the time All of this work can be done by hand using a 12" x 12" 6mm plate glass for flatness and emery cloth and dremmel for the reshaping.

funny that when i was 16 the MT5 was a honda...

now the yamaha dt 50 x is really popular. At least in finland.

@@ruuvivaras6305 Nice, i hate yamaha for not making them anymore or any newer dt 50 really. In norway, every person i meet with mine, are shocked because they want a dt 50. The problem is that you can barely find ones in good condition for a decent price. Everyone be riding around with Rieju mrt 50s, and there is always a problem with them. Dt50s were very popular back when they were made tho.

@@lengaming1651 you can find a bunch of Yamaha DT's in Finland. I got one for 150€, but it was in really bad condition. It was rusty, the paint was bad and it didn't run. But I'm planning on making it a 70cc sport supermoto. I do really wish they made them nowadays, but I guess Riejus, betas and fantics are ok too. I have a Rieju MRX and it has so many problems, despite fixing it all the time.

@@ruuvivaras6305 Beta rr seems to be the best these days and they are still being produced. Easy to find parts, deadly performance when tuning it right and good quality over all.

I agree with you. I made this video long before I uploaded it. By raising the exhaust duration, I am losing torque and also getting a smaller and more concentrated powerband at higer revs. I normally like to keep my cylinders at a blowdown at around 30-35 when it comes to the transfers, but it depends on what type of ride and powerband I want. The piston thing is not needed as you say, and it will also result in a bit of lost torque by lightning the piston.

So not true!!

What about reversion, wouldn’t raising the exhaust port without raising the transfer decrease diversion?

Kan se hva jeg får til😀 går mest i cr kjøring for tiden

DidrikNaper Fungerer den fortsatt? Vurderer å kjøpe enten denne elr en orion agb 37 på motornorway

Nei, Bjørge er en ordentlig smart kar.

@@skar6001 Regner med at det var ironisk ment... Hvis ikke må du nesten forklare meg hvorfor han er "ordentlig smart"?

@@njr8744 han snakker fakta

@@skar6001 Nei for faen, nå må du holde opp! Om du så er bare et nettroll som skriver dette på kødd, så ikke gjør deg selv så jævlig dum! Du vet åpenbart ikke hva "fakta" er for noe, men du tror vel som alle andre konspirasjonsteoretikere at det er et begrep du kan bruke akkurat om det du vil. Du forstår heller ikke hva du skal gjøre når jeg ber deg om å forklare hvorfor dette sinnsyke vrøvlet er smart, sikkert fordi du egentlig vet at du ikke kan forsvare det. Bjørge her latterliggjør seg selv på tv foran hele Norge, riktignok i et idiotprogram som er basert på å latterliggjøre en gjeng av mildt sagt originale folk! Men du trenger ikke gjøre det samme, så bare la vær å spy ut dette tullet. Om du fortsatt mener at Bjørge's idè om hvordan olje oppstår naturlig er riktig, har du fortsatt sjansen til å forklare med dine egne ord hvorfor du mener dette, og hvorfor noen andre burde høre på det...

Hei, artig liten sak dette, men ikke spesielt holdbar. Sliter med girkassen på denne 2. Gir hopper ut. Gjør ikke noe, men kan være irriterende. Ellers må jeg hele tiden gå å etterstramme ting fordi de holder på å falle av, men alt i alt en veldig morsom sykkel som du kan ha det mye gøy med :-)

DidrikNaper okej, tack så mycket för svar.
