You do know the K is kilometers not MPH ?

You do know the K is kilometers not MPH ? He posted the other picture of the speedometer to clarify the video for people who aren't familiar with the Tao Tao's gauges. He was having indicated speeds of over 100 KPH!!

Was joking and those speedos with 10 inch wheels are way off the faster you go the more wrong it is

hahaha yeah he's right about taking the indicated KPH and cutting it in half though, that was very consistent with my GPS verified speeds. My 2nd Tao Tao seems to be more accurate though (12" wheels)

My Echarm was 1 MPH of radar and my 2T with 13s was 4 MPH over

They equipped the Tao with a large gear, and light rollers (though could be lighter). Engine 'shifts gear' or belt goes up on the variator ~5k RPM. From a dead cold engine, just start and go, it'll go 40+ GPS within 1 minute. Once the engine is hot, it'll go much faster. I've also noted way less engine vibration with the spark plug gap.. It could be because of a better seal, or perhaps the spark plug gap does something to earlier detonation. The day I hit 60 (thanks to the truck), the needle was completely horizontal to the right. The same kind of thing happened to me years ago on a Honda Elite 125. (back when the speed limit was 55mph.) The engine got hot (I was on the interstate) and hit an astounding 73 mph (digital speedo) and for awhile I was passing everything in sight on my little "moped" ;D Still remember the shocked look on one trucker's face.

The "spark plug mod" as I call it, is just taking out the stock spark plug, and gap it to 0.10". You'll need feeler gauges for that. Stock, an iridium plug I purchased, came with 0.25" gap. If you live in a colder area, you may want to increase the 0.10" gap a bit. In a hot environment (like with temps in the 80's), the 0.10" gap works just fine!
As far as indicated 100kph, I probably was +100kph, and when a truck passed me by on the highway, cutting all the wind for me, the speedometer was horizontal (~56MPH GPS verified; kinda hard to say exactly, because the speedo numbers cut off at 80kph).

It's so fun pushing that little meter past the left turn signal on those things. I never got mine horizontal though, that's haulin' some serious grass. I'm gonna try to gap my plug smaller but it's still gonna be a little chilly for a few more weeks.

Reminds me of a Honda I had with a swapped engine, the stock cluster redline was 6200 the new motor could handle 8k. Just bury that needle!

I'm glad I'm not alone! Many here did not believe me, when I said my Tao did faster than 48MPH! The ~60MPH I only gained when the truck was before me, for a short time while it was cutting my wind (going like 1MPH faster then me). Without wind cutter, the ATM50 tops out at ~53MPH, which is just under the blinker light!
I use BP Premium fuel, gap the spark plug, installed a windshield (contrary to many's belief, I believe that a windshield does not significantly increase speed). I've also changed the tail light with a dual tail/brake LED light (tricky business, as the bulb socket is very weak).
I believe what the tao ATM likes most, is a reduction on the power draw, and by changing the tail light, you could easily save 15-20W. The spark plug regapping probably saves most power.
Despite all this, I'm still running tests on my EVO150, but if they all turn out ok, I'll probably be selling my ATM50. I love the great gas mileage on it (~98MPG), but hate the lack of acceleration, always wanting more. The EVO150 has just that, enough acceleration, though it does not go that much faster compared to an ATM50 (only 10MPH, however I hope it'll improve a bit, as the engine breaks in to ~500 miles). It does, however, maintain it's speed better on uphills and when having a lot of wind against! Gas mileage on the EVO150 is not bad, but I had expected better. Right now it's ~75MPH, but I hope it'll improve to 80MPH or more.

Hell yeah I would consistently get in the left turn signal area on long straight aways when the wind wasn't too bad. I really think a windshield and smaller plug gap would have helped even more, I gotta call that kid and see if we can tinker with it Hard to compare to my current scoot cuz it's a slightly different model and has an 83cc BBK. Worlds apart in acceleration but similar top end speed.

This was a solid fairly consistent top speed at the peak of the weather/tuning on my ATM50-A1 but with a windshield I tested it was faster.

To me personally, an ATM50 with a 72-75cc BBK would probably be the best of both worlds. The 50cc is only lacking a little bit of acceleration or torque. When you upgraded to a BBK, did you change the jets on your carb? And how much MPG do you get?
I've said it many times before, but if the ATM would be released with anywhere between 75-100cc it would be the perfect MPG machine for 1 avg weight person! 100-125cc is perfect for upto 2 people.
Low CC's, high MPG's, and good enough acceleration. 75cc = 50% more displacement from a 50cc.
Or if a person's weight would be ~300LBS, then he would benefit a 100cc scooter much over a 50cc; while still getting better MPG's as a 150cc or 200cc.

I believe I'm running a 91 or 92 MJ with the 83cc kit now. Stock exhaust for now for noise considerations although the cone filter intake makes it pretty loud at WOT. The main benefit I was going after was not running WOT all the time like I used to run my '12 ATM50-A1. The tuning has some room to go but I don't feel like I have to push it balls out anymore with the extra cc's. Climbs hills at solid 35 MPH even with the RPM's pretty low due to CVT tuning. Could easily push more top speed but I don't need it. Not sure of MPG yet, havn't been keeping very good track but I would imagine with my conservative tune and less WOT now it probably is pretty good.

I used to only get mid 80's on my ATM50-A1 with all the tuning and mods I did, but I had a pretty long commute for a 50cc 3 times a week at WOT 40+ MPH almost the entire way.

I once reached almost 108MPG with my ATM50. The best speed to be cruising at is ~35-40MPH. The variator maxes out ~35MPH, so RPMs and wind resistance are lowest at that speed. Doing a continuous (and long) run @35mph, could possibly give you 110-120MPG on the stock ATM50.

yeah it was inbetween 100-110 when I first got it after break-in, but I wasnt riding it all the way to north campus yet and not pushing it too hard around here. then mid 90's after changing variator weights for a while until I upjetted with the colder weather and modified the intake & exhaust to free up some airflow. Even still, a 5 mph increase overall and still getting 85-90 was cool with me.

Most like me use Dr Pulley sliders they last longer and perform better . I have 4,000 miles on my belt and it still looks like new it is a Gates but I will be going with a Bando when its time .
I still do not see how you get that much MPG . My Echarm says 80 MPG in the manual but MPG varies alot with speed and terrain . When I had pedal mopeds they would get 150 MPG but were slow and did not hit high RPMs
I want to get an Ecotrons EFI kit on my 2T as with a BBK , pipe and upjet it can go through gas quickly when I hit 10,000 RPMs . When it was stock I could get almost 100 MPG if I went 40 MPH or less since a 2T can coast with no tranny drag like a 4T does

The Ecotrons EFI kit for a 2T you can have TWO injectors and program it to kick in at a certain RPM , sweeeeeet .

Post by stiv625 on Feb 23, 2013 2:13:10 GMT -5
There's some serious potential there considering what I've seen just regular 2T's do. 90cc BBK w/ dual injector EFI?!?! holy cow I'd ride that thing from here to California hahaha

The high MPG ratings can only be attained at certain riding conditions. I mainly did long and continuous rides. The longer rides, heat up the engine which results in better MPG, and there's not much braking/acceleration going on.
My rollers are also stock rollers, they probably go upto 6k RPM, not 7 or 7,5k RPM.

Ditto that, I had great mileage until I put a massively bigger jet in the carb and used 4g rollers (stock was like 7 or 8g). Gained a helluva lot of speed but that's the price you pay. They run pretty lean from the factory and I never got below 100 mpg to a tank/gal the first 1000 km or so before I started modifying things. Also the traffic around here is more go than stop so that helps.
