Sounds like the contra was not moving, possibly stuck in one position.

I had good top end speed and it would downshift when I slowed down or came to a stop. I think the spring was working, but it should not have burned my belt like that.

Today I installed a set of mirror extenders. They move the mirror up about 30mm and out about 40mm. I had to buy adapter nuts because Banggood sent me a 10mm set and my mirrors are 8mm. (They were out of stock on the 8mm extenders, so Banggood refunded my money and told me to keep the 10mm set). The adapter nuts raise the mirror about another 15mm, so the total raise is about 45mm.
I want to see something other than my arms.

The belt burning would be caused by the contra not moving and applying pressure to the belt. A variator not moving would still have the belt under pressure by a properly operating contra. The contra is the problem.

I have been wanting to do a manual shut-off valve for a little while now...just never got around to it. So, I would suppose that once we swap out that stock vac. petcock, we just block off the vac. line as close to the manifold as we can get? (I can't remember if mine runs direct from the manifold, or comes off a Y fitting somewhere.)

My vacuum line came off the intake manifold. I'm sure you can buy plugs for them and put a clamp on it.
The one the guy at Thumb Powersports made for me is about 2" of the proper size line. You could probably do this at home, soften the end of some plastic fuel line (unused of course - Boom), then crimp it together in a vice, let it cool to harden, make sure it doesn't leak when you blow through it, then cut the desired length and install with a clamp.
It might take a couple of tries to get the right amount of heat, but cheap & easy.

I have an assortment of vacuum port blocking caps that I bought from somewhere not too long after I got this scooter. For some reason, I think I remember it coming off a Y connector...but maybe that was my PAIR system? I will check this weekend. Either way, the caps will work on the connector or the manifold port...just need to locate a decent, small ball valve. Bill |

Measure the threads on the outlet of your tank, mine was 16mm, but they range in size from 12mm to 18mm (I was shopping on Ebay and there was many sizes). Most Powersport stores should have them in stock. I bought mine for $16.95 + tax. About the same as Ebay with the shipping, and I got it right away.

I would never mount it on my tank...I could never reach it without removing about 20 minutes worth of plastic. (I really, really hate dealing with that plastic!) My vac. petcock is mounted on my frame on the left side under my seat. I will just 86 that and replace it with a manual valve that mounts to the frame and sticks through my plastic for now. When I replaced all of my fuel and vacuum lines, 90% of the time was spent removing, and replacing that plastic. I moved my fuel filter to an easier to access location at that time too. I have a simple barb attached to the bottom of my tank...what did you have? Brent said there are some different set-ups out there...no surprise right? Bill |

My fuel petcock mounts to the bottom of my gas tank. I probably could have searched for something with just a barb, but I was in a hurry to get my scoot running (nice days now and not many more left).
The powersports store had the manual petcock that also mounts to the bottom of my tank in stock, so I bought that one.
My Dongfang is exactly like a Taotao ATM50-1, just like the 1 Brent has, same bodypanels & lights.

I remember I had a heck of a time just getting the old line off that barb, and then getting the new one on there. I could barely fit my hand up in there. That is why I just fed the fuel line down toward the engine before installing the new filter. My old one was just about under that tank! Now it is easy. I tried 3 times to post a photo of the valve installation that moat pointed us to but it won't load it for some reason..."unknown error"...my favorite kind. Oh well. Bill EDIT: Ah, there it is.  |

I had to remove the gas tank to change the petcock! That meant removing the entire back body, seat and the bar that the seat lock attaches to (the taillight assembly also attaches to this bar, had to loosen that up also), then I could squeeze my tank out. Fortunately, the old vacuum one was shorter and it came out with some jockeying, but the manual one was longer, so I had to mount the tank, then the petcock (I attached the fuel line before I installed it- damned impossible to get to otherwise).
With the body off, I hooked up the rest of the fuel line.

That is what I am probably going to do as that is exactly where my petcock (vacuum) is located now. When I see these guys with their naked scoots...I stare in envy. If it were not such an ordeal to do, I would have already done it. Maybe I will just start a bit at a time? Hell, every plastic piece I have removed has had at least several of those connector things just fall off so, they are not on there like they are supposed to be anyway. Hmm...now I am thinking.

Now you guys know some of the reasons I hate plastics. I hate plastics on scoots. I hate plastics on cars. I hate plastics on lawnmowers. I hate plastics on appliances. I hate plastics on computers...
I have many vacuum etc line plugs, some purchased as assortments. I have many more made from a length of appropriate tubing plugged with something. A screw/bolt with a little RTV/silicone or permatex aviation gasket sealer to keep the threads from leaking works OK. Plugs should not be rocket science although some temporary plugs can crack due to fuel exposure either in a fuel line or on an intake manifold. Some will swell and/or crack when exposed to oil. I have never bothered with heat sealing tubing. Vacuum line on the intake manifold must be hot fuel proof since it is constantly exposed.

I bought some proper vacuum seal plugs from the auto parts store. Cheap and better than the one made out of fuel line.
