few scoots or motorcycles (those flimsy 50cc ones) have a carry capacity of 300LBS.
The stronger ones usually are 350LBS.
It has very little to do with the frame, everything to do with the rear spring.
You'll know when you're over the limit, when the rear fender hits the tire, or when riding over bumps no longer gets cushioned by the suspension.

Yeah, for most it's because they can't or don't want to deal with all the paperwork involved in >49cc scooters.
In Fl for instance, you need a motorcycle endorsement for a 150cc.
Modding a 49cc to a 50+cc actually is illegal, and requires the person to get the paperwork done of a >49cc scooter, but it's quite difficult to trace or prove.
And about everyone here agrees that a 4T 50cc is too slow to be used in traffic.
It goes fast enough, but accelerates too slow. So an increase of 50% (75cc), or even 33% (66cc) is a big deal in acceleration, eventhough the scooter does not get that much of a better top speed.

Center stand. In most cases you have to put the scoot on the center stand in order to be able to fit an oil pan under it.
On the center stand, front wheel automatically touches the floor.
For taking oil out the scoot, sometimes it helps tilting it to the right a bit (away from the side stand peg), or with the rear wheel down on the floor. That will allow more dirty oil to come out of the engine.

If that's the case, it definitely is restricted somewhere.
My ATM50 goes past 45MPH on a normal day. On a good day, and with little or no wind in the back it goes past 50MPH.
But good acceleration, and then a reasonably sharp decline in acceleration near to 40MPH, usually means it's restricted somewhere (perhaps they used the wrong cdi on that one, lol).

I wonder how you can test one if it's bad?
I also have an ATM and it seems inherited the same flaws

not much info on chinese mopeds though, the chinese don't have that moped/scooter law, like in the rest of the world, so they mainly make scooters.
Also depends, electric or gasoline.

ramblinman is really a good guy!
LOL!
No, I really don't know him at all, so I'd probably say:
He's never offended anyone I know (yet) ;-)

I think some people are a bit oversensitive. I've seen cas post 2 threads already about him leaving, usually over him getting into over heated debates, or him saying some things people go like "??Wut??(..the ## is he talking about)  ". |

alleyoop: Wouldn't that possibly introduce debris in the tranny? It is after all a vent hose...

On the Roketa MC-05-127 engine it is not in your standard chinese engine's place.
Look around. Even lawn mowers have them

I've been for a while on the TU250X forum (tux riders), and they only have about 2 forum members that know something about the motorcycle.
All the others don't know squad about it; because they probably ride it, not wrench on it.
Also, their views on chinese scoots is so outdated! They still think that scoots are 50cc's, and that they're for people who can't get a real motorcycle.
Last month I was on the highway, keeping up with a burgman. The guy was fast, but my 150cc kept up just fine!
Many don't know mid sized, and maxi scooters.

You have a VIP, T3, or ATM50?
My turn signals also stopped working. I guess it's the weakness of TaoTao's.
I'm at ~4000-4500km's right now. After a heavy downpour they stopped working.
I think it's either a loose cable, or the relay unit.
Also my horn works intermittent; sometimes it works, sometimes it doesn't. Have to open the thing to take a look at it some day...

What about the bushings?
What bushings are they talking about?
I never greased anything on my scoot. Any advise on how to do it, and what to choose?

It could be a misbalance between the idle jet, and the main jet.
I think your bike is still running rich, but the idle jet is running lean. Causing you to have a perfect plug color. I'd suggest to take a step down on the main jet, and increase the idle jet by a step; and adjust the idle screw a bit lower, to level out the bigger idle jet.

They also mentioned this bike (unlike most chinese bikes) is made for regular people, not tiny toddler sized chinese people. The recommended size is between 5' and 6'. I'm 6'3" but keep you updated on how it fits me.
These bikes come from the warehouse without PDI, so I'll have to open every body panel, check every bolt and nut.
Going to be crazy!
I'll try to take many pictures as to where is what, and if I can, I'll also note what to do first (like usually one panel can only be opened after another, etc...).
I bought this bike for a new experience. I want to experience the gears, the 125cc engine which I have high hopes for, and seemingly it looks to be taller than I had imagined; like almost Ninja sized (still small for a tall person, but taller than the chinese choppers or bobbers).
The schematics don't display the right Teeth sprocket, but from the photo's I deducted that the rear sprocket is 41T 4 bolts. I presume the front sprocket is 15T, in which case I probably will want to reduce the rear sprocket to 35T, if that would fit, but I'll see all of that, when the bike gets here.
More than likely the gears are 'tuned' to shift:
1 - 2 gear : 10KPH (~6MPH)
2 - 3 gear : 20KPH (~12.5MPH)
3 - 4 gear : 30KPH (~20MPH)
Then from 20MPH in 4th gear, at ~2k rpm, it could accelerate to a good 60MPH at ~6k RPM.
It most likely has a 1 to 100 ratio on speed to RPM; sounds most logical, it is what most companies do.
But that would also mean that the bike is best 'tuned' to ride in the 30-35MPH zone (as I believe these 125cc engines run best ~3k RPM).
If it could get a front sprocket change to 16T and a rear sprocket change to 35T, it should have gained a respectable 7.5MPH top speed @ 3k RPM (in 4th gear); raising it's most optimized cruising speed from 35 to ~ 42MPH (which would be excellent to ride on those 40MPH roads, as most roads around here are 40MPH).
Also when the gearings would change to 1.25x larger, upshifting would happen around:
1 - 2 gear : 12,5kph (7.75 MPH)
2 - 3 gear : 25,0kph (15.5 MPH)
3 - 4 gear : 37,5kph (23.3 MPH)
It doesn't look that much difference, but the end result should be at least 10MPG extra, and a max of 15MPG extra with just these sprocket changes, so expect MPG's in the 80's.
Acceleration from a stand still is a bit slower, however it pretty much evens out once you're riding, as the larger gearing will allow you to stay longer in a lower gear (while on the stock gearing you'll need to upshift faster).
Top speed should still be about the same or a few MPH's faster, the good thing is that you might reach the same top speed in 4th as in 3rd gear; 3rd gear offering more torque to overtake on the highways, 4th gear offering better fuel mileage (as RPM's drop by about 25%).
This all is speculative, I still need to see if it's possible to do a front sprocket change or not; how small of a rear sprocket the frame can support, and what the engine is able to pull (too big changes may result in the engine not being able to optimally use the gears; like difficult starting from a stand still; and top speed in 4th gear to drop too low).
I know for one thing, the stock gearing will be too short, allowing fast acceleration, in which case most of the time, you'd leave most cars well behind yourself on a red light, even with a passenger.
So getting larger gearings allows you to trade some of that fast acceleration, for better MPG's, and funner riding (as I believe it's a lot more fun to ride a bike where you have to shift gears less in traffic, not shift every time you slow down 10MPH).
This gear change may not be for people who have to do a lot of hill climbing, are riding with more than 200-250 LBS (I'm only 165 with gear, 170 tops). I mainly ride level ground, no hills, not a lot of wind.
