New to scooters picked up a YY150Y-12 By eprovenzano (Read 1,111 times)

Not new to wrenching on motorcycles, but new to working on scooters...  

My son picked up a YY150Y-12 scooter.  It's a 2014 with 750 miles.  Not sure the last time it ran...  of course the battery is flat and will not charge, the gas tank was almost empty.  That as much info as I can provide... as that's all I know about it:D

Tried kick starting...  it will run... barely.  It will idle weekly for a few seconds but then die.  If you try to give it any throttle will die immediately.  Based on it trying to run, I'm assuming spark, compression and fuel delivery are ok...  I'm thinking a complete carb cleaning will needed to get the scooter to run.  

I've watched a few vids on carb removal... seems straight forward.  I'm also going to see it gets all fluids changed... again not sure what's been done, and what's not been done.  Will change fluids once it's up and running. 


Is there anything else I should be looking for?

Welcome,,,that's pretty much it,,,probably the carbs jets are gummed up/plugged,,,,I'd set valve lash as log as you're in there anyways,,,but I think the carb being dirty is the problem here

The more I research / read about these machines, the more I agree I should also set the valves while I have the carb out. I'm also pretty sure the oil will be nasty too... I doubt any real maintenance was done the the scoot.

I'll let you know what I find when I pull the carb...

Why not change that oil now? Who knows what's in it...water?, gas? Because it only holds 3/4 of a quart, and has no real oil filter to replace, it will cost less than a small cup of coffee from Dunkin Donuts, to do the job.

As suggested above, check those valves....I'd do a complete PDI. These little Chinese scoots will deliver years of dependable transportation, and tons of fun, it maintained, and operated properly.

Get that nasty stuff out of your crankcase.

I’d change the gear oil too
