Differences between two tao tao scooters.

get spark plug part number 7544 at advanced auto parts no need to gap it, its an irridium

[scootnwinn]

Tire should not spin at all when idling sorry the other post wasn't clear... I should have said turn the idle down until the wheel stops spinning. Idle speed is around 1600 rpm and clutch engagement above 2000 rpm...

Sorry for the typos and ambiguity...

in-case you dont wont to buy a 9 dollar plug ngk cr7has are 2.50 and the plug millscmention is also known has ngk cr7hix

Thanks guys, I have the scooter wrapped up in a tarp right now for the night. I'll go back out in the morning and let it warm up and see what the rpm it idles at. Glad it has a gauge for that or I wouldn't have an idea of how to test it lol. And I may just get the cr7hix aka the 7544 if that is the best recommended one. I was going to change the oil in the scooter to synthetic but I read on another post somewhere that using synthetic to early in the bikes life may cause it not to set correctly. So I'll wait until 1000km before doing it. And in the mean time just use regular oil. Any choice on oils?

[millsc]

I use 10w 40 castrol non synthetic all year around, unless its a new top end then i use 15w 40 rotella t to break in unless its under 40 degrees

[scootnwinn]

I like the castrol 10 40 too all year round... Motorcycle formula of course available at any auto zone. Synthetic is probably a waste of money if you are changing every 1000 miles...

Thanks I appreciate the suggestions. As soon as it's time to change the oil the first time I will use the 10 40 castrol since it got 2 thumbs up right away.

Try to set the spark plug gap to 0.3mm; 0.3 or 0.4 (stock, from the factory they come at 0.635mm). On my ATM it works best at just over 0.254mm.

Good job on the idle adjustment!
You'll notice, that now, the idle is set correctly, but especially if it's set from the handle, and not the carb, that the idle will differ with temperature.
You'll have to adjust on the carb too.
You'll notice that now it might run well, but on a 50 mile trip on a hot day, your scoot might be idling at 2k RPM, and wants to go forward on a red light.
That's bad, so it needs to be re-adjusted after the cold days pass.

As for oil, depends on your temperature.
At below 60 degrees, 10W30, or 10W40 will work just fine.
below 80 degrees, 10W40 or 15W40 work fine.
above 80 degrees, 15W40 or 15W50.

Unlike many people's reviews, the only reason why to get dino oil in the breakin, is if the dino oil is cheaper. Any other reason is not valid. Mobil actually recommends it's synthetic oil even for breakin!
I personally did my ATM50 with synthetic, and had fabulous results, better than most other people!
If synthetic or semi-synthetic oil is the same price, get synthetic (because 90% of synthetic oil you'll find in the stores is actually dino oil, with synthetic stabilizers in, not actual 100% synthetic oil, unless it's like 2-3x the price).
Also at the breakin you'll be throwing away the oil WAY before it becomes bad.
You throw it away because it has particles in it (metal flakes, carbon,....).
But your oil will only be worn for less than 5-10%.

Anyway, Castrol, Valvoline, Mobil, all good brands.
There are few 100% synthetic oils out there, but IMHO they're a waste to use on a chinese scoot; because a tiny engine is just not handling super good oil very well like a large engine (a large engine could do way longer with fully synthetic oil than a scooter. On a scooter, regardless of oil life and condition, it still needs to be changed every 1000km's).

Dont gap the irridium plug you'll most likely break the electrode, leave it be no need to gap the irridium plug

[teddy554]

+1 on that, 9 buck down the drain there

[scootnwinn]

I agree I never gapped the one in my 150.

[prodigit]

150's generally don't need a spark plug gap modification, as they have a better stator.
As far as gapping the spark plug, you don't need to break the center pin. You can bend the arm a bit, and if it's bent too much, bent it back with a screw driver without even touching the center pin.
The outside arm is fairly bendable, so it's not like you will break it anytime soon (unless you perhaps plan on bending it 90 degrees or more.

Hey I'm back. My computer got infected so I'm on my phone right now lol. I went to advance auto and they didn't have the cr7hix in stock. So I went to autozone and they didn't have it either so they said they could order it but that I would have to gap it. I said to the m that dont sound like the plug I'm wanting as u guys said it would come pre gapped. I also bought a 5 quart jug of 10 40 castrol. And some seafoam. My next question is how much oil will I be pitting in this scoot since the manual doesn't tell me these things lol.

[scootnwinn]

Less than a quart ir until the stick says it full

just have them order the plug it will be pregapped don't worry about what the highly trained auto parts specialist tells you...

+1 dont gap it advance auto parts always orders my plugs and it comes the next day
