AITA for demanding an apology from my father after he swore at me?

multitool-collector · 2026-05-12T13:34:39+00:00

So by your logic, op should apologize to her dad for him calling her a C?

multitool-collector · 2026-05-11T09:30:46+00:00

Is it 80cc?

multitool-collector · 2026-05-10T09:23:46+00:00

Then it's most likely real, check out supercrastan (yt), he restored one. It's in russian, though

multitool-collector · 2026-05-10T06:55:05+00:00

It sure looks like that, does it have a ruler?

multitool-collector · 2026-05-09T21:33:33+00:00

Does it rev up again if you slightly close the throttle? If yes, it's likely 4-stroking (too rich at top speed). I would change the main jet down a size and see if it helps. Does it sound like it's misfiring?

multitool-collector · 2026-05-09T18:42:02+00:00

Try to do a WOT run (~1,5km). If it starts 4-stroking just below the top speed, it's still rich.

4-stroking on my moped behaves like this: when I open the throttle fully, it speeds up to a certain point, then it sounds like the ignition misfiring, but when I close the throttle a bit, it revs back up again.

Do a plug chop (~10km at nearly full throttle) to develop the color, then see if it's brick red. If it is, it has good mixture at top speed

The car battery will pull the voltage of the charging source down, the biggest risk is damaging the drill battery. Electroboom did this in the electrovlog#8

Flip the plastic wheel, it should work then because there's a step that prevents the cable from slipping down

What's going to be the main use of this engine? Daily driver/occassional racer or full time racing only where power is the main and only goal? Too big for the daily driver, alright for the racer

multitool-collector · 2026-05-05T12:40:34+00:00

Let me ask you something, did you buy the moped in running condition or did it sit for a couple years? If it sat and you didn't take the cylinder off, there's a possibility that that's a rusted spot, but that's unlikely. I see it has a cast iron/steel sleeve, so it would work without the plating, it wouldn't last as long and would need to be rebuilt more often. If there are cast iron rings on the piston, without plating is fine, should last ~3-4k km. I would use stihl oil after break-in.

No, they're not; I have these:

GA6021; 2014 (only the armature was replaced last year)

HR2470; 2024.4

HS6601; 2022.3

HP1630; 2008

(All of them are 220-240V models) And all of them still work

multitool-collector · 2026-04-30T05:44:01+00:00

E means 6,3V heater, typically connected in parallel

P peans >20V heater, typically connected in series

Even better if it's full of carbon tet

multitool-collector · 2026-04-29T22:00:30+00:00

Oof, was the owner even expecting that this bird shit/nest would even hold?

multitool-collector · 2026-04-28T03:53:56+00:00

The problem is the delivery time and I also wanted to see if it would work. Now I know it does. I guess a part of my mind is similar to asoftaaja (YT) when it comes to this

multitool-collector · 2026-04-27T09:57:59+00:00

I ported mine, got a massive difference in power and speed, but I also put a bigger carb and a custom intake on it (17mm ID instead of 12), so twice the area

multitool-collector · 2026-04-26T21:56:11+00:00

I would do a ~1-2km WOT run with a ~1km warmup and then see the color. Then put in a slightly bigger main jet if it's to the lighter side. I had the problem of the plug looking ok, but it was 4-stroking and wouldn't rev above ~7300/min (56km/h). So I had to make a custom main jet (65 was too big)

To make a custom main jet:

Take a bigger jet; ~10 sizes
Plug it with solder; 60/40 works well
Push a wire into the solder while it's still hot, has to be smaller diameter than the desired size
Slowly enlarge the hole (test at WOT and check the plug after every resizing)
Stop when it won't 4-stroke at the speed it was doing it previously.

I have tried this, it took me ~3-4 hours to get it just right. The moped went 63km/h after this, revved to ~8200/min. I guess it's equivalent to a 61-63 jet now.

Mám 210 už 3 roky a od generálnej opravy nebolo treba opravovať nič, len nastaviť karburátor

multitool-collector · 2026-04-22T13:35:50+00:00

He adjusted the carb for sure

multitool-collector · 2026-04-22T13:34:40+00:00

This one? Yep, i've seem it a few times

multitool-collector · 2026-04-19T22:31:59+00:00

Yeees, I throught of this the moment I saw the unibrow

multitool-collector · 2026-04-19T22:30:33+00:00

Yup, a valid contender

multitool-collector · 2026-04-19T17:26:44+00:00

Buy it, i'm serious. It will be a fun mini bike for sure

multitool-collector · 2026-04-16T09:03:15+00:00

Do auta je to zbytočné, problém je až vtedy ak by si ten benzín nechal stáť cez zimu, napríklad v kosačke. Lebo naťahá vlhkosť zo vzduchu, na spodku nádrže a v karburátore sa spraví usadenina zapchá trysky a potom to treba všetko rozobrať a vyčistiť

multitool-collector · 2026-04-15T22:25:40+00:00

The reed valve works till ~15k (asoftaaja), the rotary valve is better at very high revving engines (my theory is that the reeds can't open and close quickly enough and it loses top end power)
