I did some research on this. You guys are right. Removing that washer would actually reduce the speed.
The washer that is commonly removed from small scooters is a different one, like the one below.

Hi Everyone,

Has anyone tried to remove the spacer (washer) from behind the variator to allow it to push the belt further out and achieve higher higher speeds?

Thanks.

Hi everyone,

I have a GT 200i with 30k kms in it. I use it almost every day and recently has started stalling out as I go uphill on a ramp coming out of an underground garage. I cant even restart it while I'm on the slope. I have to roll back and it takes ~30 secs of cranking to get it going again. What could this be? How is it possible that a slope can even affect the engine? It has an injector. It's not like a carburetor engine where the level of the gas in the carb changes along with the level of the whole motorcycle...

Air filter, spark plug, oil and drive belt were recently replaced.

Any help is appreciated.

I have the same pin in my cam shaft as this one on this photo that I've found online, when I searched for "Kymco 14100 cam shaft":



On the above photo I think the pin is there because this cam supports variable valve timing.
I don’t think these engines (People GT) have VVT, so the pin remains mystery.

I decided to do it, so here are my findings:

All four valve clearance gaps were spot on (0.1 mm).
I've also found out the source of ticking. First, here is the video with the sound of the engine:

What I've found out is that there is a pin embedded into the intake valve cam. It is a small pin that I can move horizontally with a small screwdriver. At a certain position of the cam the cam follower of the intake lifter will sink into the groove of that embedded pin and as a result the cam follower will make that sound as the spring forces it to nest in that groove.
This is the pin embedded in the cam:

Here is the video showing when it makes the sound (twice - beginning/end of video):

Anyone else experiencing this?

Highly unlikely but still very likely. Have you serviced on a regular? Is there excessive white smoke or lack of power?
Backfiring? If non of the above I wouldn't worry too much.

I've followed the service schedule. No white smoke and no lack of power. I can hear some vibration that sounds similar to ticking, but more when it is warm and not really when it is cold. It should be the other way around if it is from the valve. I think something got loose and vibrates. I'm loosing a lot of bolts due to vibration. I'm wondering whether it is mine only or all these scooters run rough... 

Hi all,

The more I ride this bike the more I think that probably you guys are right. I'm used to riding a 50cc minarelli. There was almost no engine brake with that. This one is just too much. I've checked again the speedometer to see at what speed it pulls back and it seems to pull back around 10-15 kmph according to the speedometer. However it feels much lower speed than that as the speedometer reading is very delayed. I'm sure the bike is rolling less than 5 kmph at that point as I almost loose my balance when it happens.
I think I just have to get used to this.
I know the cvt system as I have worked on a couple of them, but they were all 50cc ones.
I've pulled off the plastic cover and the cast housing of the cvt drive. The outer side of the driven pulley moves nicely back and forth against the spring, so it is not the grease that sometimes get contaminated or dries out for sure. In order to know more, I need to pull both pulleys so I've ordered a universal flywheel tool.
Regardless, I now really believe that all I feel is the fact that this engine is much larger than the ones I'm used to and that's all...
