yeah, 80kmh is 50mph, which is pretty slow for a 150; nothing spectacular. And yes, you can ride it on the interstate, because the minimum speed is 50MPH; 50MPH, which my TaoTao ATM50 (4stroke 50cc) just can't reach without some back wind

Probably a custom mod would be the way to do it...

Yeah, never changing oil can seriously mess up your engine.
That being said, I've known a girl who hadn't done any maintenance to her original Honda scooter for many years. The oil was a black smudge, the thing always overheated, but survived many many years, and many miles.
That being said, should she have done proper pdi, her scooter would have lasted her much longer (perhaps upto 5 or 10x longer)
On my 150, a quart oil jar is a tad too much (takes just a little less).

If I where you, I'd try to get a 2 stroke,the least. It should give enough power even for a trike to ride around in most city environments; not on the highway.
If you're lucky you might be able to maintain 40MPH on the highways on the uphill slope of a bridge, or with strong wind.

Well, I only suggested to try it out for those of us who have SM tendencies; the tough guys, and those of us with great curiosity in life.
Never tried it myself though, but sandpaper rubs about as fast as 20MPH I think...
lol

If you ever wondered what road rash feels like,
you can create a similar environment, on a small scale, without the disastrous effects.
Just buy a small piece of large grain sand paper; make a fist, and rub the sand paper hard over the back of your hand.
If you want to make it more realistic, rub it a bit faster.
If the experience is successful, you should see small scrapes where blood comes out. If it's just red, or skin peeling off, you haven't performed the experiment successfully.
If you did perform it successfully, then 'Congratulations'!
You now know how it feels like to ride and fall without protection at ~20-25MPH.

Do you have the <08 or 2011+ version?
the 2011 versions come with EFI, the 08 and prior versions come with carburetor.
The carburetor can be set incorrectly.
I also think you may have air in your hydraulic line. get that checked out!

For a 4 stroke, the red line is ~8k rpm, but they rev in neutral or off ground to 10500. Did it before, though would not suggest anyone to do that.
For a 2 stroke, 10k RPM is not unheard of.
My 150 actually does 63MPH on the speedo. My manual geared Roketa MC-05-127 (~125-127cc) actually shows 60MPH, but in actuality does 55, with power spare.
So it's possible to breach the 60MPH limit on a 125cc.

I love the sym, but at $3k it's not really worth it; Besides all that chrome is actually steel, and going to rust in a few weeks! I like that it's a manual geared 150! Great on gas, has a rear sprocket that you can change (because like usual, these bikes are always tuned too low in gears), and it's got a tach, something my bike doesn't have. But I don't think it's worth the 3k price! For that reason I bought this one: www.superiorpowersports.com/127cc_motorcycle_p/rk127mc-05.htmAt just over $1k shipping incl. it's a steal! I atually bought it a bit cheaper than what it is online right now! It has it's problems, but nothing you can't work around! Stock, it's a great replacement for a 50cc scooter; but it's not going much faster than a tuned 50cc 4 stroke. With a sprocket change, I will be able to get more out of it! |

 Most chinese bikes are single cylinder bikes, and can be tuned to have great gas mileage. My bike has a choke. I can manually adjust it to run at peak performance (by slightly opening it, I can adjust the AF ratio). I can also run leaner than optimal, though I prefer to get all available power to my wheels. To have a choke, is wonderful!

Strange,
I wonder why the ATM50 gets so much more on insurance.
It supposed to be a 49cc unless they're registered as a 50cc!

Yellow, red, light green, orange, all great colors.
Why go for a 50cc trike? I hope you know they usually don't go very fast (<35MPH unrestricted)?

Yeah, sounds to me like there's a bad AF ratio somewhere, maybe a vacuum leak, may be something broke in the carburetor, maybe the fuel line is clogged, petcock not working well...
Could be a lot of things, but it's fairly safe to say that most likely the issue is that of an AF inconsistency. Since running lean makes the engine sound different, I think it could be running rich.
Check the spark plug, see what color it has... (black usually means rich).

Guys, could we keep this thread about the MC-05-127 please?
If you'd like, please create a separate thread about how you feel about name calling/turbo language, or whatever; or like Hank said, do it in a PM!
This thread has way too much info on the bike, to be locked; so please, don't allow this to happen...
Riding my motorcycle today, I noticed once again how short the gears where, and how surely a sprocket change would bring a GREAT improvement to all this!
With all the metallic parts in the oil, I don't feel very comfy running the engine at top revs all the time, just to go 55MPH!
This is not a 50cc scooter, it should be able to go faster. I've been contemplating on trying out the 34T sprocket, and buy a 32T sprocket too, and see which one feels best!
If I can run the 32T, I will, and be selling both 34 and 36T sprockets!

Update 6/14 300 odo meters (not sure if it's km or Mi, think km).
I've noted a large amount of metallic parts still in the oil after the initial oilchanges.
Oilchange interval seem to be on par with the 50cc's, meaning:
50km, 150km, 300km.
The initial oil that came out looked like new, but for some reason there was a lot of debris in the middle/end of draining the oil.
I suspect it has something to do with the gearbox and engine using the same oil, but also, the piston seems horizontal (perhaps the top isn't lubricated enough), but the oil in the compartment is about the same as that of a 50cc engine. Very little, barely wetting the bottom of the crankcase.
I tried 5W30, which was too light, and the clutch started skipping. Now I put 10W30 in there, much better, but still some minor clutch slip at the peak of it's torque band. Probably going to switch over to 10W40 like the manual says.
Also when the engine is hot, the idle RPM's go up to the point where the bike is wanting to go forward (clutch gripping).
I'm having a faulty contact somewhere, the electric wiring is not working properly somewhere on the fuse.
