No.

It is thin because the screws are normally torqued to the manufactures spec that compresses the gasket so it does the proper sealing.

If you are not seeing a break in the gasket, it is doing what it was designed to do, seal the cylinder to the head and provide passage for the coolant. I think pulling off the head was an unnecessary step.

I think it must be the bearings or the associated hardware that either has failed or come loose.

I was home at noon. I checked tires earlier today, but did again at noon. I check all hardware on wheels, brakes, etc. All looks to be correct. While standing in front of the scoot, I grabbed the handlebars and I can wiggle the bars back and forth and to the sides.

Now I need to figure out how much or hopefully, how little I need to take apart to do a full diagnosis and repair.

I have checked online scooter parts stores and do find bearings, so at least they are available and there is a bearing store not too far from me, so if I can figure out what is wrong (bearing or otherwise) I should be able to get parts soon.

When I think head gasket, I think either coolant fluid getting into the oil or oil getting into the coolant, a loss of pressure in the head, and finally smoke usually at start up when oil or coolant gets into the cylinder and burns off when first started.

If the coolant is suspected of not flowing, it can be checked by disconnecting one side of the scoot radiator hose probably near the fill. Connect a garden hose to the scooter hose end that was removed. Turn on the garden hose to a low flow. If the water doesn't flow, the thermostat could be pulled and (I think) left out when the unit is assembled. Retry the garden hose flush. You should get water through the radiator and engine and dumping out the radiator fill cap. If you don't, something is plugged. If you do, (if the old method still works) you may want to check the thermostat with hot water on the stove to see if the thermostat opens at higher temps.

Hope I am not giving bad advice, but the cooling system isn't that much different than a car cooling system. It should be able to be verified about the same way.

Rich, When I removed the hockey puck fuel pump, I used one of the holes to mount the new pump and did drill an additional hole for the second mounting tab. To be honest, the job would have gone much faster had I grabbed the corded drill and not the cordless drill. The battery would hit the frame so I tried an extension for the drill bit. The corded drill would work just fine without a drill bit extension. That was a 'duh' moment.

I'll attempt to post pictures soon.

I don't post much, but thought I would provide an update.

1) I took the MN Motorcycle Safety Foundation and have passed the classes. I will have my new license soon. I took the test on their motorcycle and am still amazed that I passed. That tight box was hard for me to balance, not sure why, but I did it.

2) Some over 750 miles on the YY250T scooter. It has been a great ride to work. No riding this past week, 90-102 degrees is just too hot.

3) I have added LED front blinkers, big improvement on visibility. I have replaced the spark plug (looked a little lean). I have put on a bike speedometer and now know my actual speed.

4) Today, I am adding the Mr Gasket 42S fuel pump. I have had a problem at take off from a stop when I crank open the throttle. I also need to adjust the throttle cable (too much slop) and will add Counteract balancing beads to the front wheel. Maybe the magnet I glued to the wheel for the bike speedometer is throwing off my balance, but I hope the beads smooth the ride.

I get on the site and read a fair amount. From what I have figured out, I have the Honda Clone engine. I do need to research further for the valve adjustment, (external slide valve adjustment), not I have been doing it from feel and sound, but I believe there is a better way.

Thank you all for the helpful posts and especially the pictures and youtube videos. A picture is worth the the thousand words and very helpful on finding 'where that thing is'.

Yeah! I have my plates!
I found the reason the scoot wouldn't start. There is a fuse block near the battery with 4 fuses. I had pulled each out, checked things over and replaced them. The terminals in the fuse block were not properly seated and two of them terminals were pushed in so the fuse didn't make contact. I was able to pull out the block, push the fuse contact terminals in place and it started right up.

Saturday, when the weather is warmer and it isn't raining, I am taking the scoot to a nearby parking lot to just get some back and forth runs to learn the handling before I get onto the traffic.

And on a side note (referencing my sig line) after a couple hours working on the scoot last night, I put a homemade pizza on the big green egg last. That was some good eating.
