I have a 2009 Eton Matrix 50, picked up about a month ago. The scoot has 550 miles on it so far and until this morning ran great. This morning, the engine stalled out at every stop light! Restarts right away and runs very well under throttle. Much of my commute requires me to run at full throttle, but as soon as I stop, the engine slowly revs down until it dies. Any suggestions as to what may be wrong? I think that I may need an idle adjustment, but I would welcome any advice from those more experienced!

I would let it warm up and adjust the idle first, see where that gets you.

did this start happening after a fill up? Could just be some bad gas.

The stall did begin to happen after a fill up. I've been filling it with 89 octane, per the owner's manual. I will try a different station next time. I usually top off every other day as I commute about 35 miles round trip. I give the engine at least a five minute warm up before starting out.
Tried the choke suggestion before when I had about 200 miles on the odometer. Found I didn't need to choke at all.
Thanks very much for the advice! Hope I can repay the favor some day.

It could be old gas since it happened just after your fill up. You also could have a little moisture in there. Get a can of Seafoam or HEET and add the correct ratio per your gas tank volume. That will get out any moisture or crud.
Also, did you notice a big difference in temperature where you live between when you got it and now? If so, it could just need the air screw adjusted.

First off, a 2 stroke won't need a 5 minute warm up, it can foul the plug if you're running slightly rich already. This may be the case with you, a slightly fouled plug, or you might need to bump up the idle slightly. Also, just a tip, I stepped up my plug to the next hotter NGK, with fantastic results (better idle/cleaner burn). Just remember, with NGK to go hotter, the # for the plug with actually be a lower number, i.e. for the Beamer, stock is BPR7HS, so you could try a BPR6HS, or even a 5 (I've been using 5's for about a year now with no problem).

The one time I allowed my 2 stroke to warm up a few minutes, it would not accelerate twice, just went to idle when I opened up half throttle. After a couple of blocks it went away, and I rode over 100 miles that day. Flooded sounds right to me. Now I go within 30 seconds of start, no problems.

Scooter moran, if you are planning to put additive on plugholes, be advised that there are hard rubber seals in your crank case. They can be eaten out by harsh chemicals(Sea foam) or striping agents (carb cleaner).
When they start to leak U get air leaks (Lean cyl burn condition) & the seals themselves then leak inj oil into the crankcase. Or worse yet you could strip out the crankcase airtight seals.
Putting unknown stuff in your engines, down the carbs, or in the spark plug holes can do more harm than good !!! I personally would not put anything in the engine except stuff rated or made specifically for two strokes(if U have a 2 stroke engine).
I would not....
Put Carb cleaner down the plug holes... Mystery oil cleaner down the plug holes or carbs... Seafoam directly in the plug holes...
All these could cause harm to your motor(s).
i agree with Karl, Seafoam goes in the gas, not in the plug holes. hope this enlightens, thanks

Yes #1 buy the highest octane 93 , you can adjust the idle it is on the side of the carb looks like a knob, try adjusting it a little while it's running just enough it doesn't stall. I believe if you turn it just a little clockwise it will pick up the throttle a little<I would remember how far you turn it in case it is just bad gas.
