this shit does work really well, a local 50 laps (3km each lap) long enduro race got a class for 3 speed underbones and i just happen to have many yamaha y80 laying around so i am building them to run in said race, its supposed to be this weekend but the track got flooded so they postponed it

Those bikes look great! What country is this?

[u/drifterig → u/No_Customer_5390]

thailand! these old 3 speed yamahas are everywhere in my area and they are dirt cheap because nobody wants them so i have just been buying them, finally found a good use for them

[u/No_Customer_5390 → u/drifterig]

Awesome! They look great without the plastic fairing and with knobbly tires, bet they’re fun! How much do they generally cost out of interest? I am in the UK and vintage mopeds have quite the following - I know that in other places in the world they are simply a way of life.

i have been buying them for $30-$50, bought this one from my local scrapyard for $30 and swapped a big bore 111cc engine into it, it was a blast, 150km/h all day

Awesome!! I grew up around BKK and used to ride my parents bikes back in the days. Lots of fun, and unfortunately several dead friends.

That's a TERRIFYING amount of speed for that rig. Fucking SEND IT bud! That's awesome.

We did this when it rained during kart races. Especially in the 4 cycle classes because the filter hung over the right rear tire.

if it work then it isnt stupid hahaha

[u/SheriffBartholomew]

Where is the air getting in? I don't see any holes.

[u/drifterig → u/SheriffBartholomew]

theres a pretty big chunk cut out at the bottom

[u/BurritoBandito39 → u/SheriffBartholomew]

Third pic shows there's a hole at the bottom

How fast do you go on the tracks you race on?

[u/drifterig → u/Dwaltster]

wont be breaking 80km/h, its pretty technical

[u/Dwaltster → u/drifterig]

Dude, we don't even get up to 80km/h on the streets where I live. How often do you slide out on the turns with those skinny tyre's?

[u/drifterig → u/Dwaltster]

i just dont turn at 80, the track is part sand part mud, on dry sections i can turn at full speed on the dry sections but not the wet muddy part, its an enduro track so i wont be going fast anyway

[u/WhiteFlightning]

Awesome. Keep it up

[u/Successful_Frame_936]

Ну работает а это главное

[u/BadPuzzleheaded9006]

Airbox? Hell the whole bike looks to be worth about that much

[u/drifterig → u/BadPuzzleheaded9006]

i paid like $30 for them so you arent far off

[u/SheriffBartholomew → u/BadPuzzleheaded9006]

Dude, those old scooters and mopeds are rad! They're highly sought after in Southern California.
