I've got a jet kit but they're generic chinese ones, as well as a screw in the bowl being stripped out, so I haven't messed with it yet. The CVT seems to like 4.5-5g better because I tried 6g rollers and it dropped down to around 33mph from 35 at the time. I see carbs with stripped out bowl screw heads all the time. A secret I learned is to take a phillips screwdriver, put it in the screw, and then tap on the handle a few times with a hammer and they usually come out. If the head is stripped, I take a punch or equivalent (like a 3/8" extension) and put it on the head of the screw and hit it with a hammer a few times to mush the head down a bit. Then take a phillips screwdriver, line up the slots, and hit it a few times to make new slots. Give it a turn and they usually pop right out. The biggest thing is that you use a good screwdriver with a really good tip and is the correct tip size. |

I seen your video on removal of the PAIR system but I wanted to ask a question or two. I've noticed all the PAIR systems I've seen pictures of have a tube that is attached to the valve cover. Mine is just a metal pipe that comes off the hole in the head then goes to the PAIR system. Does that make it any different to remove? Will removing it have any effects that I need to note of? As far as I know, I don't need to worry about emissions inspections in Illinois so I wanted to remove it so fighting my airbox and carb wasn't so annoying with that stiff tube.

Mostly it just gets some extra stuff out of the way. As long as you block it off, it shouldn't have negative effects that you'll notice, unless you monitor emissions.

I see, that's what I thought. I just looked it up and supposedly IL requires an inspection every 4 years after vehicles manufacture date, which means I probably shouldn't mess with it =\

This thing keeps ending up being neglected even though I don't mean to. I do still hope to do something with it this year instead of letting it sit with no videos as I have. When you've got a 100cc 2T and a 500cc 4T sitting next to your 49cc 4T, it's really not good for motivation. If nothing else I need to do an update vid of what has happened since the last Project TaoTao vid, but I'd like to work on it more.

Place your neglected child on a 1' stand, then put a spotlight on the ceiling that turns on with the garage lights.

If nothing else I need to do an update vid of what has happened since the last Project TaoTao vid, but I'd like to work on it more. You could turbocharge it. I have seen about 10 Youtube videos of guys doing this...or should I say, guys TRYING to do this. If i recall correctly, about all of them could never get it to start and idle once the turbos were installed. Of course, some of them were trying to use huge turbos from like a car or something but, it would be great to see one sized for the 49cc range that was installed correctly and actually worked and increased the h.p. Possibly one from a snowmobile? Just a thought. This topic is still the most detailed and well explained 4T scooter topic to be found anywhere so, it probably really does not need anything added.

Even with a big bore and stroker so it's near 100cc for real, the turbo would likely not be successful. It's been discussed a lot on forums, but I don't recall much success. What's sad about a 100cc turbo 4T like this, is that a 70-95cc race 2T would still double it's output with off the shelf parts. If you ever could make enough boost to get near competing with built 2Ts, it would start killing the engine and CVT for sure. I watched a guy on a pocketbike forum years ago working with nitrous on a pitbike engine till the head studs couldn't even hold it together anymore. He tried some different things, already had parts from larger ATVs in the engine and eventually called it hopeless. I like to ride stuff, so you can't get anywhere near those ragged edges for real use. Same forum, a turbo company made a project out of a 110cc pitbike. They made about 3psi and I think a 114cc kit would have outran it.

My vote is for a smog pump supercharger.
I think they even make electric ones!

I think the turbo and supercharger suggestions are because you actually want to see me so mad at the TaoTao that I do some Wile E. Coyote type $%#! to it when I can't get it in tune or making boost. It would save a lot of trouble if I knew where to get one of those big Acme homing rockets to launch this sucker back to the TaoTao factory.

I had started to look at "boosting" the induction to the Maddog...but I was consider using something I saw on an old dragster....they were using large compressed air tanks to avoid the parasitic drag on the engine...I thought a fiberglass tank like firefighters use for SCBA's would do the trick...
Never got beyond the idea...hadn't even considered tuning.

Finding a small SCUBA or SCBA tank and a shop around here to fill it to crazy pressures (3,000psi) plus finding a way to close the inlet off from atmosphere when the air pressure boost is active and so on would likely be all sorts of "fun". Not saying it isn't an interesting idea though. Plus figuring out fuel and timing and so on.
If dealing with a pressurized tank, I bet a 5lb nitrous bottle lasts a long time with a 0.008" jet and refilling stations and knowledge are more plentiful. Being different is cool, but to be fair it's not like I'd run across anyone else on a Tao Tao with nitrous around here either. I don't even really think I want to do that because of the expense involved when I end up with a full system to make 2-5HP extra till it comes apart when I hold it too long racing a rental scoot.

It would save a lot of trouble if I knew where to get one of those big Acme homing rockets to launch this sucker back to the TaoTao factory. Strapping a rocket to it would be the best idea. I wish I thought of that.  On a serious note, I bought one of those supercharge science books years ago. I remember clearly it saying that high rpms is worse for a motor than boosted lower revs. I know those 50cc European road racers have hatched up some superchargers. Better yet, I think a leaf blower would do it. |
