It doesn't start with the lid on or if I choke it with my hand.

Mabye you should take it to a bike shop and get them to fix it

The problem continues. Fires up like a champ when cold and runs great, but can't start warm.

updates:

Uni filter is installed.

New spark plug. Plug chopped coco brown.

Battery is good.

Petcock is good.

Jet #90.

Premix is around 70:1

Greetings:

Can you post up some pics of the left side of the engine? The area around the carb, fuel lines and the carb.

I'll take pictures tomorrow.

Did you leave the lid on?

When you choked it was the lid on?

I can get it started warm if I use starter fluid, but it is impossible to keep running. I took it for a couple longer rides ~8-10 minutes and it died both times on me while at complete stops. It didn't die like hitting the kill switch but like it was running out of gas.

is it possible that a vacuum leak could get worse when its warm?

I have read all your post and I really believe you have a bad ignition coil. I had the same issue with several outboards and lawn mowers in the past. The coil leaks voltage when it gets warm. It could also be that your starter is pulling enough amps away from the coil when the starter is hot that the coil isn't getting enough juice to provide a good spark. If you had a kick starter this would be easier to troubleshoot.

Something else..... once you use starting fluid to start it I would either throw that plug away or at the very least clean it. The starting fluid leaves deposits on the spark plug. Spark plugs kind of get addicted to to starting fluid and makes for hard to starting unless you use it again.

One last suggestion is to replace and/or find the covers that go over the bystarter. At the same time look over and check the operation of the bystarter. The covers are designed to keep the bystarter warm and prevent it from choking the motor with more fuel on restarts under warm conditions.

Well-written. That's why I wanted to see some pics. Sorry I didn't get around to making that comment myself in time.
The coil and many other potted electrical components are another possibility. MouseWheels knows why, but it really happens more often than you'd think. Harleys with the ECM up betwixt the cylinders are notorious for heat-related failures. The bikes run when cold, but the fault appears with heat before the component fails altogether.

I thought it was possibly the coil or the cdi so I bought a used pair off of ebay. And....the problem still continues. How do I test the coil? What comes before the coil so I can test that? I'm I missing a cover from the bystarter?

I installed a fresh plug today, because the other one was tainted from using starter fluid, and it took longer than normal to get started. After letting it idel for a bit, I took it for a ride around the block, giving it some WOT, and it died after ~5 mins of running. Luckily it died in my alley so I didn't have to push it home. I pulled the plug after it died and noticed a little smoke coming from the engine. The plug was too hot to remove from the socket so hooked up another plug to the coil and got a blue spark.

I clearly have two problems. It quits after running hard and then slowing down and then it won't restart until it cools down. This happens with the two different coils and cdis I have.

Are these problems separate or related? Could this be a timing issue? Could I have put my cylinder head on wrong? Could the milling of the cylinder head been done wrong and be causing these problems?


Another observation:
I have a new battery that dies a few minutes after trying various restart techniques. Would a bad starter cause my battery to die quickly? Could this be why I hate my spree so much right now?

Soft sieze, richen it up or one of these times it won't be soft, but piston and bore destroying.

Since the soft seize, I have taken some time away from scooter to decompress and let the battery charge. Hooked up the fully charged battery and the starter was sounding like was a having a hard time getting things going. The flywheel turns completely but * its way around. Without the plug in the hole the starter sounds fine and spins the flywheel without a problem. The fully charged battery lasted less than 8 minutes today. Is the kit fried or is it the starter or something else?
