Omg what a story this is!
Was out driving, suddenly I hear this high frequency "PEEEEEEP" from the dashboard. Wtf - I have no such warning speaker? And no warning lights were lit. I thought it must be the speedometer or something. A while, 5-7 minutes, later I start losing power, I get a bad feeling and instantly turn off engine.
Smoke and crackle sounds, the engine is clearly very, very hot. I check the water coolant reservoir - it is empty, and have condensation drips inside.
I wait till engine cools, and walk to a closeby house and get some water to fill in. Check engine temp, it is <100 c (water from cylinder does not evaporate). So I try electric starter - no go. I feel the kick starter, it is very heavy/stuck, but it will move with a bit force - I reckon the piston/rings is jammed.
I wait a while, thinking. Suddenly water comes out from underneath scooter. When checking where water comes from - it comes out from the carb air intake (!) - the intake where the air filter usually is strapped onto (I run without unfortunately). Also zips out from everywhere - the spark plug, the 4 cylinder bolts (long ones), from the gasket between engine block and cylinder.
This tells me 2 things - water is flooded everywhere, even goes up through the reedvalve and out the carb.
Question 1)
Is it repairable, or just sell it as a junk object for $350 instead of working condition for $1000?
Question 2)
Now what, what steps do I need to follow? I am worried about getting out all the water, prefferably without splitting the engine.
Question 3)
What might have caused this? I get a feeling it might be the thermostat, since the "PEEEEP" sounded like an old tea pot on a stove, the water might have stood still in the cylinder head, eventually evaporating and forced out the top. The vapor inside water reservoir also hints the same. If it was a common water leak, then I would not get boiled water, just overheat? (NOTE: Apparently the previous owner did not fancy the heat sensor - it was unplugged). I will check the thermostat tomorrow by boiling it.
Question 4)
What should my shoppinglist contain? New cylinder kit, gaskets, needle bearing, heat sensor, and thermostat if it is broken, I presume - anything else?
Regards!
