It wasn't me.

I guess we do things different out here at chasing problems.

Without being there, Nobody really knows whats wrong with it.

Didn't say it was?

Very different indeed? Man never said or implied it was leaking, pressure tests are for a leaking radiator, compression tests are for engine problems, has nothing to do with it running hot.

Don't need to be there unless his information is wrong. By his information he does not have a blown head gasket or a leaking radiator. Air even the slightest amount is a killer on this engine. Thermostat isn't closed or it would heat up in less than 5 minutes.

He hasn't mentioned if he has checked to see if the coolant is circulating. If it is then it's just plain old air......but if he doesn't have coolant circulation, I'll see if the way people check out there know what the problem is?

when i pulled away "I noticed a lot of smoke coming form the muffler" I thought to myself that "if it continued I'd stop" but shortly after it stopped. So I rode on.

That is the sign of a blown head gasket = Steam looking like smoke.

Next I started losing power "It didn't shut off like before" but it was slowly dying.

It was getting HOT again.


And you still think its just air in the cooling system ? .

Missed by all including me:

So I thought to check the coolant the reservoir was full but when I looked under the seat I found a hole in the plastic filler.

Loss of power = hot engine.

Steam equal coolant coming or dripping out this hole. If the radiator reservoir has a hole in it not only is it losing coolant slowly when the engine heats up but when it cools and the radiator is pulling fluid back in the radiator there is none there and it's pulling air into the system.

We all know that these systems work just like a auto system, cap expands when hot, pulls extra coolant if needed from the reservoir tank or releases it back to the tank if not needed. As it cools off it makes sure the radiator is topped off to the full amount.

Got to fix this or it's never work right.

Lets all hope, that he didn't cook that motor.

I feel kind of bad for breaking out the bad guy here but I look at it this way, for $700 you just took a really good course in experience so that when in the future you ever experience this kind of behavior in a more expensive vehicle (such as an automobile) you will know that you need to leave it pulled over where you first stopped and call a tow truck, because if you don't you could be looking at replacing an engine that in a car can easily cost you 7 or 8 thousand dollars, so for $700 you got away cheap.

The unfortunate part on these 250's is that, if you did fry the engine, it's going to cost you more than you paid for the vehicle itself, something the seller may or may not have known about. Chances are, if you ask me, he knew something about it but decided to sell it before he got into knowing the full extent of the problem, that's just my opinion but in fact a moot point.

Now I think the engine is all right but you need to address the problem and stop driving it in hopes that it will go away, because it won't. Your problem is likely either a stuck thermostat or possibly a blown head gasket, something along those lines is what I would be checking into.

Personally I would start by replacing the thermostat, because it's cheaper and far easier than the head gasket.
You never know, especially if the scooter still has coolant, that might be all it is.

Good luck
