Yes, the previous Airsal 80cc setup was much more better to drive on the street for longer 80km/h roadtrips with more low/midend torque. But I mostly drove around the same town just enjoying the powerband and the setup lasted for 6000km+ with the next owner.

A lot

Das öl war einfach schlecht. Am ende des videos hört man, dass es nach dem aufwärmen gut funktioniert.

Derbi D50B0

Nope if everything is correctly done. I had some issues on the beginning of the build with the crankcases because the crankshaft bearings were not fully tight on the worn out housing and that caused the piston to slowly hit the head and the piston ring got stuck few times without damage. But after sleeving the housings and re-gapping the piston ring groove(to get the ring unstuck), I drove it with 0 issues for 2000km until I sold it the next owner and he drove 5000km+ easily with the setup.

@@-JX- would you recommend this type of bike for daily use?

@@lunatikas140 Remember, more power = more maintenance. If you have knowledge how these engines work and what kind of service they require and how to keep them running then yes. I ran mine daily. But if you don't know that much and just need a trouble free setup, get Airsal 80cc (the normal one with 2 piston rings). That thing will be bulletproof with proper crankshaft and good oil and proper carb settings.

@@-JX- well you see i have a 125cc 2t right now (for enduro and stuff) but soon im turning 15 and i want something street legal with simiral amount of power.

The reeds lasted for about a year, you can just cut new reeds from a carbonplate and it won't be that expensive.

@@-JX- okay and which ones did you have?

@@anglofil5489 I had the TPR VForce3 made for AM6, I modified the holes slightly to make it fit Derbi D50B0

@@-JX- did they make a big difference?

@@anglofil5489 Unsure, I changed a lot of parts at the same time. But they didn't limit atleast.

Show your tune. The power range is very limited at these type of engines and it will bog on certain throttle positions if you make it leaner at middle. As you can hear, it screams fine when used in the power range the engine was designed for. My 80cc set had a lot more lower torque and it was a lot more streetable due to the characteristics of it's ports. It did not sound raspy like this does at down low/mid.

It was fine, just oil going bad and causing the slipping when cold. Next owner used the same clutch setup for 5000km.

If you use quality parts like I did and you modify the block, you can get the same result/very close result. Not sure about "sport 90cc", you need a race spec cylinderkit and crankshaft.

People even use their clutch? I only use it to start and 1st to 2nd.

@@raybla haahahaah high end people be like :

@@ekion. I wouldn't really call a Derbi drd pro and a Husqvarna wr 125 high end. But it basically works on anything.

@@raybla well if you ride only on streets then you basically need just 2 gears, then u basically told me that you just ride slow

@@ekion. that makes no sense at all. Unless youre talking about 600cc+ street bikes.

Description has full specs in English.

@@-JX- ok thx

380-440hp riippuen ahtopaineasetuksesta. Suuttimien asetukset rajoittivat videon aikana kun oli väärät datat, ecu luuli bensansaannin loppuvan vaikka varaa oli.

wtf im so retarded

Bruh, not after the oil warmed up. :)

Sure, checkout Scootfast. :)

Oliko jotain 13000€~ luokkaa kaikkineen kuluineen 2016, oli melko huonossa kunnossa sisätiloistaan ja ulkoisesti paitsi pohja oli kuin uusi. Eli rahaa on palanut ylimaalautuksiin, sisustan osiin, muoviosiin, tiivisteisiin, listoihin, valoihin, clipsuihin, kiinnikkeisiin, moottoriin jne tuon jälkeen reilusti.

@@-JX- mutta luultavasti halvempaa ku suomessa tommosen metsästäminen (?)

@@umeet4144 Ei nykyään, kun tuli tuo 25-vuoden ikä Supralle niin samalla avautui jenkeille markkinat. Hinnat pompanneet absillisissa manuaali vapareissa jo yli 20k luokkaan Japanin puolella kysynnän takia.

@@umeet4144 jos ei rahaa löydy niin kannattaa vaan ostaa ge automaatti ja laittaa mäntien öljyruiskut zz puolat gte/aftermarket nokat ja cd09 loora

he's using 15 teeth sprocket in front and 53 rear

ZachosKam _ I’m using 14/55

It's not always about the placement, ports and flow are more important. Those cheap ebay kits have quite low exhaust & transfer port timings that tend to make the cylinder have more tame power range and less high end power.

60 mph with 90cc :D

Mikä siinä häiritsee, ai että väärällä puolella? Ihan samanlainen ajaa ja tottuu hetkessä.

@@-JX- se voi olla ittee vaa häiritsee siks en hommaa supraa

@@hanneletati1874 Saa nuita vasurinakin.

@@-JX-aa no jumantsuikka tommonen ostoon

@@hanneletati1874 se pitää jenkeistä tuua joka on ihan vitunmoinen työmaa

Akulta tietenkin, ei ole vaikea asentaa kun osaa hiemankin liittimiä painaa kiinni ja lukea kaaviota. Ainoa mitä en saanut toimimaan oli bensamittari johtuen derbin anturista mutta sen voi laittaa esim neutraalivalolle käyttäen DRD Pron anturillista hanaa.

They're in the description but, Mainjet 148, Idlejet 58. This all depends on your setup, I recommend starting from a bigger jet and trying smaller jets if it's running rich.

Starts but cuts out straight away had a 21mm carb now has a pwk 28mm race carb jet size unknown

It was even more lovely in real life.. I miss the sound.

@@-JX- wow i wish i could hear it.... :(

Jonkun verran, tankillisella pääsi about 100km~

JX no söi varmaan tankin 50km kurittomalla derbillä pääsee 110km tankilla

I did, by myself at my garage.

Resonoi kaikki maailman kiinnikkeet, katteet ja muut pienillä kierroksilla kun kyseinen setti ei ole tasapainotettu sille alueelle. Hyvin toimi vielä uudella omistajallakin.

Nice paljolla raaskit myyä?

Myyty jo 2-vuotta sitten. :)

Oot aika hyvään hintaan ton putken hommannu. Hommasitko uutena?

Käytettynä, sattui eteläsuomesta löytymään aikoinaan. :)

@@-JX- ite sain voca 70-80cc carbon putken 130€

Yes, on the beginning only. The transmission oil was 130km driven after rebuild, if I remember correctly and after changing the oil: problem was gone. :)

Thank you. :)

I didn't have cash for that back in the days. I already sold the bike. :(

+Janttux ohh, but Why did you sell it?

Because I needed cash for a car. I began building this bike on 2012 and finished it in 2016 with this setup and looks. Now I'm hunting after a Toyota Supra and going to improve it's performance as much as I can. :)

+Janttux ok :)
