Okay... A bam is never good. To work through the problem it happened on a steep hill. That means a lot of load placed on parts. Get ready to check various components as members suggest solutions.
The first question is where do you think think loud pop or bam came from? If the scooter is still running the engine could maybe ruled out. Have you looked inside the CVT? First thing I thought of was the belt. Going up hill with that stress maybe the clutch.
We need you to start looking at parts to find something "weird".

I have a problem that I want to get a second opinion on. I have two good scooter batteries. I don't want one to go bad, so I'm wondering what is an exceptable storage life.
Long story short, I was having problems electrical starting. I first thought it was the battery and replaced the factory battery. That didn't solve the problem. Went through and replaced every electrical component and continued to have electrical starting problems. In the end, not a big deal, now I have electrical spares. In the end, it it was a stupid mistake of not reconnecting the valve cover ground after checking the valve lashes.. DUH!!!
Now I have an extra good factory battery. I wondering if I should just save it and occasionally trickle charge it, or swap batteries monthly to use both.

I've noticed this on my 250 also, I always just assumed my jetting was a little off so it ran better at 7/8th throttle rather than 100% open. sometimes on long hill pulls I'll back off a hair and get a push. Do you have a vacuum petcock or manual? Mine is a vacuum operated petcock. I've heard at WOT the petcock may experience vacuum starvation. I've been meaning to switch to a manual setup, but haven't found the time and I avoid working in my garage during the summer. Everything is bigger in Texas, even the temperature during the summer.  |

I tested this out on my TaoTao Powermax 150 last night, and this "trick" worked for me. Here are my observations from the test.
Typically, at WOT my chinometer tops out at 100 with 7000RPMs. That's exactly what I tuned my CVT for to avoid the 8000RPMs. This was how she was running last night. So on a straight and level road I maxed her out. Once I was at that limit I eased off the throttle a 1/4ish for a moment then twisted back to WOT. To my surprise the chinometer climbed to 110 and RPMs reached 8000. Once I saw it worked I slowed down, but I was very surprised. My scooter has never gone that fast.
I don't think I will be doing that very often. I drive for reliability not speed. Plus the road I drive to work has a speed limit of 45. I don't want to be that guy pulled over for speeding on a scooter. But it was fun to push her limits.

Have you done any carburet tuning. Specifically, what size engine do you have? And what are your jet sizes?

Don't forget about the gear oil. I change the gear oil when I do the engine oil.

For a 50cc, intake should be set at .003inch intake and .004inch exhaust.

Yes, a slight tap is good, rattling is probably a bit lose. I agree with JerryScript. If the noise is too annoying you could set the valves to .003inch intake and .004inch exhaust. They will be a little more quieter, but you will have to check them more often. That's what I have my 150cc set at. I check them every other oil change. Just remember, a light ticking is good, rattle or banging is bad. Once the ticking goes away, you are overdue for checking them. |

scyner ... Where did you find the LED light bulbs? I've been looking for some myself.

Stater motors are very easy to take off. Just remove the two bolts then wiggle it out.

Just buy an O ring kit. Amazon has them for around $20.
If you don't want to spend the extra cash, take off the starter motor and take it with you to an auto parts store.

take a video and name it watch a 3phase stator smoke 3 single phase regulators. I was hoping you would weigh in on this discussion. You are the electrical guru here. |

It would be an interesting experiment and is very thought provoking. But I would defeat the purpose of a 3 wave setup.

Just make sure you are using inches as a unit of measurement.
