New Like 50 2t + Newbie Rider = good juju (life, breaking in a new engine, etc.)

That is what I feared. Even with the plus or minus 2 given in the specs, 130 would be the lowest in a perfect world.
I haven't taken a look yet in the exhaust port, but then I would have a heckuva time without a lift anyway.
So, after my mechanic gets it and tells me about it and we figure out and fix the problem, should I consider going to a larger main jet or is the 88 okay so long as I leave the restrictor in the airbox?
Of course, in a perfect world I would get a tunable carb, but that is not in the cards anytime soon, especially with the cash I am about to shell out, if only for shop time.
I would like to think that if the fuel system were 100%, with the compression I am getting that some manner of start would be in effect.
On a completely different note, (and part of why I won't have spare change for a carb), know any shops that carry Heidenau k58s? Rainy season is coming here in Florida...

Sweet. I have been poking around the heidenau site and saw that you had put some on your People and was hoping the k58 was something tsg carried. I had them recommended for rainy, partially sandy conditions and while the kendas have been okay, I know I'll need a more substantial tire for all season travelling. I will, of course, need to get my present situation sorted out.
Back to my sitch - prior to my acquiring the Tecnigas I had 'derestricted' the stock muffler, but only cut the one tube, not realising that I could/should have cut and crimped the one for the 'emission control' as well. I only ran like this for about a week and a half, but is it possible that could have added to my scooter's present state?
If I had a garage or even if I didn't live in fear of the condo association, I would have no issue with being more exploratory, but I can't pull apart my scooter in the parking lot with the current rules under which I live. Changing out a muffler or pulling the seat for observation are one thing, but creating a work area and spilling gas is right out.

In my opinion that is what caused the problem. It was the same as an exhaust leak leaning the engine. Your putting on the new pipe only gave you a "grace period" as the damage was already done.

Josh'll hook you up!

My hope is that my mistake means new rings at the most. Like I wrote earlier, I am about to learn an expensive lesson, but hopefully not crazy expensive. My mechanic is a fair human being and I certainly trust him. Och well, someone had to do this first on this forum for this scoot. May others heed the warning:)
I still wonder, though, if something isn't awry with the fuel pump or such.

Infos re: colder plug - What is available stateside is a colder iridium BR9HIX, which I may opt for after diagnosis and fix, though I haven't ruled out Zombie's recommend.

[wassonii]

And so my scooter is off to the doctor. Being an honest person, I let my mechanic/dealer know what mistake I had made with the original muffler so he didn't judge our air/mainjet experiments as the primary culprits in this episode. I'll get a diagnosis later today/early tomorrow and will report back the findings.

[wassonii]

Well, I got my scooter back today. May I just say damn, I missed the smell of 2 stroke exhaust.
It wasn't a cheap lesson, but turned out better than expected, cost-wise.
New Piston and rings and cylinder. I got a look at the old piston. Yikes! Black and charred and scratched. I didn't test it against a flat surface, but it looked a little warped as well.
The inside of the original cylinder looked fair until the last few millimeters which were scratched and black.
When I mess something up, I certainly do it right.
I am now having to break in a new set.
He also adjusted the oil pump to put out more than the factory setting, though not fully open.
As I wrote before, the hole I drilled in the airbox is well covered and the restrictive piece is back in the throat of the airbox. Do I want to put the silencer tube (corrugated rubber hose) back on?
I'd like some thoughts on break-in procedure, if possible. I never thought that the Kymco "30km/h for the 1st 1000km was totally necessary. My intent is to variate between 1/4 - 3/4 throttle most of the time and after a hundred or so km add full throttle into the mix occasionally keeping it easy going for about 500km - 1000km.
He did suggest adding about 1 oz. of 2 stroke oil when I fill up in addition to the Seafoam I use (about 1 oz per gallon).
Lesson learned.

I have read that with 2 cycle break-ins initial heat up and cool down cycles  are important along with varying rpms and not holding wot for extended periods at first . Maybe others could elaborate on this . Good luck .

[wassonii]

When I initially had gotten my scooter, the references I had were the owners manual and internet. From my previous message, you know what Kymco says. Online was everything from what you have written to 'ride it like you stole it' In the initial break-in period, I was pretty good about varying and then got a little careless with the variation toward the last 500km-1000km. Dregni, in "Scooters: Everything You Need To Know" says this: "...breaking in a new engine requires sedate riding at ho-hum medium speeds. Follow the manufacturer's recommended break-in procedure, which usually suggests calm, practical driving for the first hundred miles (at least) and not topping out the rpm just to wake the neighborhood." Haynes Service and Repair Manual says this : "1. Treat the engine gently for the first few miles to allow any new parts to bed-in. 2. If a new piston, cylinder or crankshaft assembly has been installed, the engine will have to be broken-in as when new. This means a restraining hand on the throttle until at least 300 miles (500km) have been covered. There's no point in keeping to any set speed limit - the main idea is to keep from laboring the engine and to gradually increase performance up to the 600 mile (1000km) mark. Make sure that the throttle position is varied to vary engine speed, and use full throttle only for short bursts. Experience is the best guide, since it's easy to tell when an engine is running freely."
Your point, juice, is well-taken.

Very happy you have it back in one piece. The vary the throttle approach is best overall. Hang on to your used cylinder. It can be bored/honed to the next size piston. Kymco does NOT offer 1 over parts but others do.
Before you ask... What is the OD of your stock piston?

[wassonii]

Glad to have it back. I was lost:) Hope the weather is as nice there as it is here and you are enjoying it!
I didn't ask to keep the parts when I picked her up, but went back today. My mech. was kind enough to dig them out of the scrap bin. Due to being outsode, there is a little oxidization on the cylinder.
Specs indicate for piston/cylinder that piston o.d. (5mm from bottom of piston skirt) is 38.970 ~ 38.955/cylinder bore is 39.0 ~ 39.025
Here's some pics:

[wassonii]

And thanks for the recommend on the throttle variations. Definitely taking it easy. After about 100km I will add in full to the mix (of course for short bursts only!).
Here's pic of the cylinder:

[zombie]

Spray out the cylinder with PB Blaster, and stuff a soaked rag in it for storage.It can be honed to .5mm over. Here is your piston...

Yours just melted over the rings, and made them stick.

[wassonii]

Will do! Thanks very much for the link, too. Takin it easy on my little fitty...
