Yager GT 200i / Re: Kymco Yeager / Dink 200I Vario topspeed...
« on: June 27, 2024, 02:00:55 PM »
I bought the scooter with a damaged engine, so I have no idea what the original top speed was before. I am reading different things on the internet about the top speed from this scooter, going from 105km/h up to 120km/h and more.

For me it is a long time ago I was doing things with scooters and changing rollers and so on.

For now I think that because of the Malossi vario in combination with lighter rollers(?) the top speed is decreased. Probably I will soon have a look what the weight is from the rollers that are inside now...

Hi Guys,

Breaking in again for a moment :D After the rebuilding adventure from the Dink 200 previous year I used it on a lot  on regular basis, much more than my other bikes because handles so easy in busy traffic.

But another question, the previous owner told me the scooter is equipped now with an Malossi vario/clutch. The original was also coming with the scooter.

The scooter is pulling up pretty good but the top speed is lacking a bit, even there is still enough power left. With 120km/h the RPM limiter is coming in, so the max speed on the highway is arround 105km/h on the right lane.

What will be the best way to increase top speed?

Promised update ;D

Received this week the new piston and gasket from Poland.



Gave the cylinder another caustic soda bad and some honing.







Mounting the new piston was a bit of a crime, no space for putting the circlips in an easy way, anyway managed to get them in.




After putting everything back the big moment, not starting and no compression :o

After cracking my brain I suddenly found this part in the belly pan, chain guide I never seen before. Must have felt out when I removed the cylinder head



Stupid mistake, after disassembling and trying to put everything back together the chain felt of the sprocket from the crankshaft, great...

Anyway, some hours later the Kymco is starting en running pretty good.  8)

With grinding I meant honing/stonegrind yes, didnt know the translation for that.

But well, I think you have a good competitor then! ;D





The piston pen was stuck as**** But I got it out 8)



And a photo from the scooter



Few photos from mt others bikes as well, so the scooter will be a bit different caliber. :P

Yes, that one would fit. Check your current piston for correct size. (pls see pic)
My set would be too expensive with spedition to Netherland.

To treat this cylinder and remove all aluminium traces from its wall:

TAKE CARE, THIS IS CHEMISTRY and I'm not taking responsibilty for any accident!
Wear gloves, mask and eye protection!

- degrease your cylinder properly
- take CAUSTIC NATRON/SODA and stir up a small quantity in a glass jar with water, make a paste, 50ml is enough
- put this with a small brush on this traces of alu in your cylinder
- wait a while
- natron eats this alu off, but does not harm cylinder
- rinse with water
- repeat until all alu is gone

Great, that was already in my mind, good to hear the confirmation.

I got some caustic soda left somewhere, but also some 2k drain dirt solver. Both I use to get rid of the melted aluminium particles that are sticking to the cutting tools from my CNC machine.

Today I did some attempts to soak and brush the cylinder wall with the dirt drain solver. Wall still looks terrible but getting better slowly it seems, if this will be a succes I will buy such a cheap grinding tool for doing the last pass to recreate the marks.

Need to be sure the cylinder wall is good enough before I will buy the piston. Will be later today or tomorrow.

Anyway there is still some hope left. ;D I will post some photo`s later.

Thanks already!

It is a 176cc. A quick measure from the pistion says 62mm.

Can not upload a photo from the piston at the moment but that is not looking good at all! No possibily to save that...

What about your complete kit?  ::)

Otherwise I saw this one: https://en.50factory.com/parts%20news/104900-piston-kymco-dink-200-o62-mm-side-a-meteor.html I guess it is the correct one and and affordable price, although a complete kit would be better perhaps because the cylinder needs some attention also for sure. Pretty much clogged aluminium to the wall.

Well, that was disappointing today :P

The piston is pretty damaged, the engine was very warm it seems and the piston is dead. Hopefully I can save the cylinder with some labor. Unfortunately it surprises me how little parts for the Dink 200 are available.

Any suggestions for finding a new (cheap cheap cheap ;D ) other piston?

Thanks.

- Kill switch is fine, CELP/motor management light is lighting up when putting the kill switch to run
- What do you mean with tap valves correctly, setting the clearance?
- I have another spark plug cable and cap, nevertheless the spark is looking pretty strong

I tried to blow carburetor cleaning under pressure thru the nozzle. Without any effect till now. I saw in the Kymco manual another way to do it. In a closed container so you will create a kind of closed system. Will try that soon.  How do you flush an injector from the opposite side?

Didn't paid to much attention to the spark plug, the few times I took it out it was looking average, not dry not wet. So not really useful information.

- Brake lights are on while starting (otherwise even no cracking and injection at all, correct?)

Hi everbody,

Netherland buyer overhere  ;D
I bought a Dink 200i 2008 in non working condition. The previous owner said he stalled the scooter in running condition and that after one month the scooter didn't want to start anymore.... True or not true, it is what it is.

Facts:

- The engine is cracking okay when I try to start, so the brake and switch stand (signal) is fine.
- Pretty good spark, tried with two bougies.
- The injector was a bit so so, but at least fuel is coming out (see movie below) I can imagine that because of the clogged gasoline the spray pattern get bad, but a not starting engine because of this....
- Battery power is good (starting cables to another car)
- I can see the spark looking thru the injector hole (when injector is removed). Not sure if this is normal when the engine is sparking at his useless stroke...
- Tried with brake cleaner on the air inlet and injector inlet port while starting
- Tried to control the injector separately with a 12v signal
- When doing the things above sometimes there is a fire (because of the fuell/brake cleaner on top of the manifold/engine) but not a single running engine :(
- Valves are having some clearance, didn't measured anything but at a certain point both of the valves had clearance.
- Fuel pump delivers pretty good amount and pressure of gasoline



I can not imagine but it feels like it is sparking at the wrong time.

Are there people here who have experienced this problem? Would be great to hear some advice from the Kymco experts :-* Many thanks!
