Jeepsteve- was there a trick to removing exhaust from the head?
I had trouble getting a socket in there between the frame and engine plastic... i didn't want to strip something, so i will test ride the scoot and see if i can hear any noises... then investigate further.

Scooter elements- I tried your puller and the 27mm was correct, thanks.
I finally had time to remove the flywheel. I did not remove exhaust, but i was able to loosen and inspect where the starter clutch is. I could not see any wear on the starter clutch and i could not wiggle the crankshaft, so it appears that nothing major is wrong. I will test ride aftet i re-upolster my seat.
Anyone know if the gasket for crankcase is universal?

Edit- i found the source of the noise. It was wear on the left bearing in crankcase, wear on left bearing of camshaft and some wear from the chain rubbing the wall of the case.. I am going to install a new head, crankshaft, and chain tensioner.
I need to take off the flywheel and am not sure which tool to order.
It seems to measure 25 mm on the nut, but a 17mm socket fits on it.
I am not sure if I need a left handed thread or right handed either.
If anyone knows what a 16" wheel scooter needs, please let me know.
Ok inspected clutch pads and replaced it due to irregular wear on the pads.
Now it takes off slower with new clutch installed (it revs higher before grabbing), it is the same size clutch but the pads are longer than the original one. I opened up the clutches to switch the springs but the new clutch has smaller springs.
My question is: Are the clutch springs typically universal sizes? I want to try and get the 1000 springs, but don't want to waste money & time.
This clutch is for the gy6b engine so I believe it is larger than most. If anyone with 16" wheel has changed your clutch, let me know what you used. This one was purchased from scrappydog.
Thanks

I am not sure where to get the correct gaskets for this gy6b motor... That is why I am waiting to take the thing apart. I took apart the clutch again and noticed that 1 of the pads is thicker than the other 2 pads, but I doubt this is the cause of the noise.

Alleyoop- I looked at the camstopper and it stops the spacer on camshaft when turning clockwise, counterclockwise it just lets it turn.... It moves the little spring loaded tip.
I never tried turning it counter clockwise before inspecting for this noise coming from crankshaft/ variator area. Not sure if it is installed correctly, or if it is damaged. It took no force to turn it in either direction. Now I know not to turn it counter clockwise... But I still haven't been able to track down the noise, and have only been test riding it short distances to find symptoms.
I went to pep boys with my old bolt, measured the threads and replaced with a standard bolt. I use 2 washers, with a small amount of red gasket maker between washers and around the bolt head. I had took the rubber washers of original bolt and put between metal washers and head, like original bolt. It also helps to put some gasket maker on outside surrounding bolt hole. Let cure overnight. This has been working for me until I get good replacement bolts... Don't overtighten the bolt.
This is my original bolt, sorry dont have pic of the standard bolt with washers
Yes I can hear noise when turning the fan on the flywheel counter clock wise, it is grinding sound when I turn it by hand. I took the cover off and turned it counter clockwise and clockwise, still only heard it on counterclockwise... I looked at chain and tensioner, the tensioner seems to be extended and I don't see any signs of irregular wear inside the head or chain area. My best guess is that the bearing is going out... Here is a video, it has a whining or grinding sound constantly now.
I re-linked the video in the first post. The noise I am concerned about is the constant noise that is loudest when I am near the variator. Sorry for the bad video on the video in this post, I was trying to get the noise.
Zgr7- I agree with u it is hard to track down noises, but this particular noise seems limited to the cvt/ engine area...
So I started removing parts again to try and track down the noise. I removed variator and clutch, ran the engine and the noise still seems to be coming from the variator area- I think it may be bad bearing on crankshaft causing noise. I rotated the engine using a socket on the fan attached to the flywheel. It is quiet when rotating it clockwise, if I rotate it counter clockwise it has a grinding sound... This might be because it is rotating in the wrong direction. When I try to move the crankshaft on either side, it doesn't seem to have any play. I also drained the oil and I did not see any metal shavings.
Any suggestions before I start tearing down the whole engine... I would like to exhaust any other possibilities before taking out the whole engine.
If it is the bearing, is it easier to replace the whole crankshaft. Scrappy dog has one and I think it might be less headache to replace the whole thing... Open to suggestions
Ok how can I tell if the chan guides or chain tensioner are going bad. I was riding today and realized that I can hear the noise when under full throttle, it is not as obvious when the engine is not under load. I used to hear this type of noise on my Truck, then I found out it was the timing chain guides that were bad, which caused my timing chain to get worn faster and I had to replace it...
How can I check the tensioner, guides or chain for wear?
