38 pages is longer then most builds. You say you have the tools so dig in and snap some pics, wishing alone won’t get it done. There are plenty of suggestions here we can’t be there and do the work, you have to.

It's not that difficult. The one mistake it's easy to do when tackling a CVT for the first time, is tightening up the variator onto the belt. Then the nut comes off down the road. Just make sure the belt sits right into the rear pulley. Then you should have lots of slack on the belt.

hey guys back for some more input. i was talking to my buddy today and he was showing me his honda elite collection. and we started talking scoots. told him what my scoot is doing and he is saying it probbaly not a cvt issue its more or less a carb issue. like i said before. how does a cvt just go bad from sitting in a garage for months, unridden. and all of the sudden i get it running again and it has no power? guess i didn't tune it right or maybe my air fuel mixture is real bad. dont know. thats why im asking you guys what kind of next steps i can take to get my power restored to the scoot. the scoot runs and drives just no power and no speed. cant get above 30mph. and before i got the new exhaust pipe and new rings in it it was just fine. 40mph easy. never touched a thing in the cvt. so im going to try messing with carb again. my buddy was saying maybe im too lean. or too rich. so gunna clean or get a new plug and run it and see if that tells me anything. he said if its too rich it would be really black. if its white or clean its too lean. im pretty sure the throttle slide comes all the way out or out to normal height in the carb so im getting full throttle. because when the bike isn't under load it will rev all the way out. but under load no power. if you guys can help me out on where i should start let me know!!

Just curious; if you have a buddy with a scooter collection that you trust for info, why is he not checking it out? Or is he online/remote as well? This whole process has gone so long that I would say at this point if you want to work on the carburetor you'd have to go back to step 1 of cleaning it before anything else. If it has been roughly a month with a scoot having fuel in it, I'm doing that first. Then the selection of main jets for tuning. So much info about carb tuning here : www.49ccscoot.com/faq/richorlean.htmlwww.49ccscoot.com/faq/symptoms.htmlwww.49ccscoot.com/faq/carbtune.html

Be really careful and kind of roll them on the piston. If you open them too much they break easily. They’re brittle.
I’ve gotten into the habit of making sharpie marks on the crown and skirt that correspond to where the ring retaining pins are so I’m less likely to lose them.
It’s much easier to get the piston in the jug if you’ve removed all the cylinder studs.
Shove a rag down around the conrod before installing the wristpin clips for when one flys out.
Wristpin clips suck suck suck.
Oil stuff.
Nothing should take a lot of force. If it does check alignment.
You’ll have to wiggle the pin just so and hold your tongue right to get it into the bearing.

You could always reinstall the old pipe and piston rings to see if it changes back to the way it used to be at 40mph. However, you did change out the carb to the one that OldGeek sent you. So, you changed your pipe, carb, and rings. I also remembered that you had a hole in the air box tube, that you said got fixed. Round and round we've gone. So getting back to where it began, changing pipe and rings. Maybe go back to the old pipe to see if you get 40mph. No load, you say that the bike revs out. With load, you say that there is no power. I think the pipe you have on it now may have moved/shifted the power band of your bore. I say this because your old pipe could get you to 40 and the new one struggles to 30. If it is such the case that the new pipe moved the power band, you probably need to change the rollers to a different weight setting. Seems like your CVT shifts while the bore isn't making much power with the new pipe. All you mentioned is a loss of power under load. You don't mention anything about Bogging or Sputtering. I could see if you said it makes a "Bwaaaaaa" sound when you give it throttle or if it Sputtered, then it would be a fuel issue that needs carb tuning. It may very well be a CVT issue now because of the new pipe. You might need to try some different roller weights. ...or put the old pipe back on and see if the power/performance returns.

A carb cleaning couldn't hurt I suppose, but that sounds like a CVT tuning issue with the new exhaust. I haven't (and don't plan on) reading the entire 39 page thread, but if your scooter has a new exhaust and you've already been through the carb/installed a new one, then it seems logical that it could be a tuning issue. When I installed a new pipe on one of my scooters recently, it had almost no power at all between 25-35 mph, but as soon as I installed a new variator, springs, and rollers it started hauling ass again. If it's not bogging, sputtering, or the like, then I say start with the CVT.
Or if you want advice on a nice bicycle, just holler. I can definitely help you there too haha.

Yes it doesn't sputter or spit or anything. Idles pretty good. Sometime it idles low sometimes it revs high until I blip the throttle to bring it back down. But i will try old exhaust pipe and see if that changes anything. Thanks for all the help guys. The bike runs good other than the slow speeds.

Ok guys. Put the old exhaust pipe on and man what a difference. Took off like a rocket. Top speed easily within 100 yards if that. So what does that tell me?
