I know, it's like Genuine scooters you have to pull the engine mount to get it off.
Oldgeek, thanks for the warning. It didn't come with the air box so I'm hoping this will work as a good replacement. How many of the holes did you open up on yours?

I had the day off and worked on the TGB. The battery was nice and charged again and the scoot started right up. When the battery gets low it cranks but no spark. I spent about 10 minutes trying to get the idle tuned in with no good luck. I pulled the carb and went from the 42 Pilot jet to a 35. It starts fine but no matter where the A/F screw is it dies 30 seconds after I close the enricher. I was able to get it out on the street and the tune is good over 3000 rpm. It revs near 10k so it's hitting the pipe. It does have a stock variator and clutch with the stock belt, I think. Its okay on take off and raves up nicely but is really not that fast. Its the stock gear ratio I'm sure. My plan is to get it running and sell it. It does sound nice and will look good. It has great curb appeal with the big wheels and the Technigas Next-R pipe so I don't think it will be a problem. But it does need to idle. Tomorrow when the battery is charged back up I'll go to a 37 pilot and see if it's any better.
I got the one-way valve in for the oil and got that going. With the clear hose I can see its getting to the pump. I added more gas to dilute the pre-mix so it won't be a smoke bomb. I can't wait to get this gone so I can get one of the Vinos on the road to sell. Then maybe I'll start playing with the ET-2, I have no idea what shape the engine is in, its low milage but looks like it was hit by a truck.

After working on the other scooters I had some time so on the lift it went. I got it started with some fluid and the RPM's went way up. I covered the intake on the Alien and could bring them down. I sprayed everywhere no leaked appeared. I tightened everything and no luck. When I did get it below 3000 rpm it wouldn't hold the idle. Maybe 37 is too small, I'll try screwing it all the way out and see where it is. I'm limited in my pilot jets so off to treat land to get more. Battery is back charging and my next time to work is next week.

I had some time yesterday and did some playing. I discovered that the high RPM was a throttle cable problem. I made that better and then swapped in a 42 pilot. It finally idles okay and revs up nicely. Once again the battery was low and no spark. I have a new one on order as well as better bendy's from Treatland so I should get that cable problem straight. I want to get this done and out of the way.

I was off this week after to much work and no scooter time. I played with this scoot some more. I ditched the Doppler air box and went to an open filter I had. The bendy fixed the throttle cable problem and its rock solid. It starts well and will idle at 2500-3000rpm with the enricher open but gets rough after 30 seconds but doesn't die. When I close the enricher the rpm drop to around 1800 and it idles for 10-15 seconds and dies. It will rev from idle and then drop down to an idle but will slowly die. I'm thinking my float needs adjusting. On all of the other circuits the jets sit deeper in the bowl and that the idle jet is just barely slurping up what's on top but doesn't drain enough lettuce valve open. I looked at the float valve when I first installed it but I think its time to get the micrometer out and see what's happening. I will keep you posted.

I was back on this scoot today. Based on the problem with idle Dexameth had I decided to look at the slide. It was a 50 which is far to big so I put a 30 in. It started and idled beautifully. I put the seat on and it started right up. Took it out on the street, I live on a 1 block street so its a matter of running up and down the street. I went up and turned and went back down. It has power through all of the circuits but is loud. I went back up and went to turn and it died, there was no starting it so I rolled back to my garage. I pulled the plug and it was nice and chocolate. Checked spark it was good. Tried to start it and nothing. I checked the tank and it looked pretty low, I grabbed the gas can and went and bought some now cheapp premium and put some in. Tank registered 1/2 full and using starter fluid and chock got it going. Idled great so back to the street, I went down the street got to the end and started to turn and it died. These were all LH turns. Got it back and no love so I put it one the charger and went for some rides.
I checked the compression and with my crap HF gauge got almost 90psi. My good gauge gave me nothing so its time to replace it. This is a new cylinder and piston so maybe that's the problem. I test again with a new gauge. The fuel lines are full when it quits so that's not it. I am also suspecting the kill switch. Next time I'll turn hard right and see what I get. I'll trace the wires and see if anything is obvious. It may also that it gets hot at that point and something electrical quits. Ah the joys of chasing gremlins.

So with my new compression tester I got 90psi again. enough to get it to start but not enough to keep it running at speed I guess. I would think that as it heated up it would seal up better as the cylinder and piston expanded but I'm guessing not. I went back and read this thread and realized I never replaced the cylinder so I now have the dilemma of do I replace the cylinder and piston or just get rid of it as is and pass it off to someone looking for a project. What I'm looking at is this cylinder , I could then sell it as a tuned scooter. or keep it 50cc with this. I' guess I should open it up and see what I find maybe just a new piston and rings and a light honing will bring it back.

Always worth just having a look. Could be as easy as a leaking base gasket. But we know it's never normally this easy. 😁

I got the piston and rings from Partsfor scooter and installed them. Still only 90psi. I did a leak test again and everything is sealed. So off I went and it did the same thing. It warms and dies as I'm turning which means at idle. Plug looked good: I'm stumped, any suggestions would help. Below is where it sits.

Could be the infamous bad stator or infamous bad cdi pink

It is a new stator and rotor, not that that means anything. I'm afraid it is the CDI. Let me hunt that down and check the plugs on it. Do you know a good source for a OEM one.
