Yes, you have to take the Kick Starter off first See the NUT holding onto the shaft Loosen that nut and opull the Kickstart off then Unscrew the golts holding the CVT COVER to the engine and pull it off. Then you will see your BELT, VARIATOR, and CLUTCH PULLEY that actually turns your Rear Wheel.

Oh mannnn. I heard there is a spring or something in there that can pop out. Sigh. K, I'll just have to take my time and do things one at a time. Super nervous

[Alleyoop]

Here is what I think it is doing.

Ya I'm going to have to agree. Why would it do that though? Did the bendix some how like move itself IN so it doesn't catch? It seems like a common problem, as i see people all over youtube w the same noise issue and my last scooter did it too.

[Alleyoop]

They are very easy to replace You may just be able to give it a good cleaning and it may still work. All you do is pull it off and clean it and then put it back in see if it will work.
The hard part is taking the CVT cover off really.

But with that picture you can now see how it is supposed to come out and engage the Teeth on the Variator Face Plate and turn the Crankshaft which moves the Piston up and down.

Also at the same time you can see WHY your kickstarter is ALSO NOT WORKING.

Ya its not turning over and I read somewhere it could be the bendix. Do you think it could have come loose and that's why its not catching? or maybe the teeth have been ground off on it? I don't understand how all this can go wrong so quick. Is the CVT cover the thing the kick start is attached to? Does this mean I have to take the kick start apart to get the cover off? It kinda looks like it in my vid. .

The kickstart is attached to the CVT cover. It comes off with the cover. Here's a picture of what you will see with the cover off:



You can see the bendix at the top of the large variator gear. If the teeth look good on both assemblies then the bendix is probably defective. You can try the starter and watch the action of the bendix. The bendix gear should kick out and engage the larger gear on the variator. If it spins without engaging, then the bendix is bad. If you hear the whirring sound and the bendix does not spin, then the gear on the starter is bad or the fine tooth gear which engages with the starter is bad.

Ya Alley Im not looking forward to getting the cover off. LOL. By the time everything is up and running I'm going to pretty much know this scooter inside out. I'm glad as of Thursday the weather STARTS to cool down here. Will make fixing things much more pleasant

Thanks for the details cruiser

[Alleyoop]

Well that is cool, the kickstarter is part of the CVT cover LESS WORK

LoL. I'm just frustrated. I bought a new scoot so I wouldn't have to deal w this stuff for awhile. Oh well. You win some, u loose some, ya LEARN a lot

The cover comes off pretty easily. There are 8 bolts you have to take out, 4 along the top and 4 along the bottom. Take note, one of the bottom bolts secures a bracket that holds the rear brake cable and one of the top bolts secures a bracket that hold a vacuum or vent line. Remember where the brackets go for when you put it all back together.

Once the 8 bolts are out just pull the cover straight off. It might be stuck on tight as there are 2 guide pins in place between the cover and the engine case to align it properly. Don't lose those.If it won't pull off easily just tap the cover with a rubber hammer or gently pry with a flat blade screwdriver. Once the cover starts to separate watch that you don't tear the paper gasket, as you can re-use it. If it does tear up no biggie as you don't really need it.

There is no need to take the kick start lever off first because the shaft it attaches to is mounted to the inside of the cover. It is the 150cc motors that you must take the kick start off of first.

There is also probably a large plastic or rubber vent tube mounted on the forward facing edge of the cover, usually held on with a screw clamp. Taking this off first might make it easier to remove the cover.

Here is an explaination on how it works:

nice call AL, on the 150's its on the stator side

[straightbangin]

thanks gatekeeper!

Alley- ahhh so the bendex moves out, and I'm guessing maybe it malfunctioned and didn't move out or didn't move out ENOUGH thanks, great diagram.

We shall see

Also, be careful if you engage the starter button with the cover off. The bendix is normally supported on both ends. With the CVT cover off the bendix has no support from the pilot bushing that it normally rides in on the left (outward) side. Without that support it may want to come out or wobble sideways when the starter is engaged and it makes contact with the variator gear teeth.
