I can't tell what that is. Is that the air filter box?
I don't think it's possible to waterproof these things. I've never had any problems, except running through puddles so deep the air filter gets water logged.

aendlich Are you talking about the cooling shroud that goes over the cooling fan. I would not leave it off for long thats how the motor is cooled. ^^^^This is important, OP. Do not ride it without the fan cover on!!! |

I do not trust these scoots in the rain. Many have had issues with water getting into places it should not be. I never ride or let the scoot set out in the rain. If it is your only transportation , you need to go through the entire scoot and waterproof everything from wireing to the air filter. They definitely are not waterproof. I have been riding in the rain for years, though, and never had a problem, other than going through very deep puddles, and the air filter getting soaked. The wiring gets wet, but it doesn't seem to affect it. You definitely need to make sure the air intake snorkel is angled towards the engine enough so that rain doesn't go down it. The first thing I thought of when I read this post was the air filter getting too wet, but it sounds like he needs to replace the ignition switch. |

You say you turn the key, and sometimes the gas gauge doesn't even come on. That makes me think that you should start by replacing the ignition switch. You can get them from one of the banner ads, or ebay, for cheap. Also, you need to check the ground wires. This sounds like a wiring issue to me.

That blue wire reading .1acv is the wire from the pickup coil, though, and that is a reading that typically means everything is good.
This is very strange.

Those readings are fine.
You have voltage going all the way to the plug coil, but not spark at the plug? Those readings are fine. Stator seems fine.
Has to be the CDI, but that is weird.

What did you set the valve lash at?
You replaced the cylinder, but not the head, right? I'm thinking you may want to replace the head, as long as you have the valve lash set right.

Piston guy. Pretty sure it was the exhaust valve.
If it was the intake valve, then nothing was likely damaged. I read it as the exhaust valve. I just read it again, and it was the exhaust valve lash that he set far too large.
Just checked his new thread. The exhaust valve blew the seal, and was stuck open.

If there is a problem with the wiring coming out of the stator, it won't blow the fuse. The fuse is between the battery and the blinkers and taillights. Power from the stator is before the fuse, and will not blow it.

No. Nothing looks off.
Your exhaust valve would have been barely opening at .05". I'm not sure what kind of damage that could have done, but those gasses had to go somewhere. You could have unseated the rings. You could have blown the valve seals. It's hard to say. Both rocker arms should have play at TDC, if the lash is set right.
Like I said, I would just replace the top end. It would not hurt anything to just replace the head first, and if that doesn't fix it, replace the cylinder and piston. You can't replace the piston without honing, or replacing the cylinder.

Yep, setting it at .045 is far too big of a gap. You likely damaged the cylinder. Just spend the $80, or so, and replace the cylinder and head. A lot of people in this thread missed that you initially set your gap WAY too big, at .05", instead of .005". I don't know exactly what was damaged, but you just need to replace the top end. New cylinder, and cylinder head, and you will be good to go. No need to try to find exactly what is messed up, and take a month to figure it out. Just replace it.

No problem. Glad we got it figured out! That happened to me when I put an 11 pole stator on a customer's scoot. Aggravated the fool out of me.

Also, make sure the bolts that hold the stator in there are snug.

OK, I know what it is. The bolts that hold the fan onto the flywheel; they are too long, and are sticking out too far on the inside of the flywheel. I had that very issue before, and it hit me while I was half asleep that this is very likely your issue..
The solution: Take one of the bolts up to the hardware store, and either get a couple of washers that will fit in there good, or get some shorter bolts. I have bolts that are just long enough to fit flush with the inside of the flywheel. Take the fan and the flywheel off, and get some bolts that are just about flush with the inside of the flywheel, or just stick out a mm, or two.
I am pretty positive that this is the issue. Post back, and let us know. Good luck.

Is the woodruff key in place on the crankshaft arm? Check that. Is there a raised area on the crankshaft arm, that you have to align the flywheel on?
