breaking in moped

[vonn]

so i have about 487 miles on my new moped and when i hit like 350 i was just full throttling my moped will the bike be ok because idk how much miles before you break in , i don’t wanna over heat it or seize the piston will it be fine even tho i’m not really breaking in my moped

Your scoot is "broken in" at that milage,ride it like you stole it

Change the oil and ride it. The makers are of course very conservative in their suggested procedures. As long as you got a few hundred miles on it before hammering the throttle, you should be ok. Get it hot, and drain the oil using the drain plug, and then remove the second port that retains the filter screen as that will let more oil out. Be prepared for the oil to have a good long arc when you pull the drain plug away from the pan. Have the collection pan kind of close so you don't let the oil slobber all over. As the oil drains, the flow will taper and begin to fall more vertical. Wipe it all with clean paper towel or cloth rag. Most use diesel rated 15W40 lube. Wally world SuperTech is ok if funds are tight, Delvac, Rotella and all the rest will do the job. Check the level after refill with both wheels on the ground.
New engines develop the most heat compared to ones broken in with miles on the clock. That is why idling a new engine for long periods is not a good thing. Vary the rpms, backing off on the throttle now and again for best break-in. Just a few second of closed throttle should raise the vacuum and potentially pull some oil onto the rings & cylinder wall to provide lube and cooling.

Most mopeds get a hard break in anyway. You have to go full throttle, or your not getting anywhere.
Even at top speeds on a lot of roads it's dangerous.

BTW- The odometer is probably in kilometers, not miles. The odometer units are the same either metric or english as the big numbers on the speedometer which is also probably km/hr not miles per hour. Look at your speedometer closely. Also scoot speedometers and the odometer are usually not accurate. There are Federal laws that cover how speedometers read, they can never read slower than your actual speed.

Frank: There are Federal laws that cover how speedometers read, they can never read slower than your actual speed.

I guess I have been wrong forever about these little machines. I always thought they were being overly optimistic.

Duh. Brain fade. Just got it wrong again. They CAN be overly optimistic, and then will not indicate slower than the actual rate of travel.
OTOH with the quality of the drive cable, possible lack of lube on the cable, the accuracy of the speedo spring & mechanism, and the mesh of the drive and driven gears(lube?), it is possible for them to under-report velocity.

The manufacturers usually grossly indicate over speed in order to not violate the law. They are not interested in accuracy, only low cost parts which also usually means analog speedometers. Cable lube, and gears on the axle mechanism usually don't slow the speedometer, they usually break or cause wild fluctuations. One of the first indications of pending problems with the speedo is a slight vibration in the needle on analog units. The magnet drive spring usually weakens and fails showing very fast speed, it almost never gets stronger. Dirt etc entering the speedo head can gum up the needle bearing which will cause a lower speed to be indicated. That is why they are so very inaccurate. The digital ones are usually far more accurate but can fail due to misread pulses and will show a slower speed or the digital circuits can be set up to recognize the uneven pulses and shut down, sometimes with an error indication. The digital ones are also susceptible to electrical noise with various indications.

In other words, scoot speedometers suck.

Even in bigger motorcycles I've had. It's always about ten percent out.
Though the Piaggio typhoon and new Aerox with digital Speedo is certainly better than other scooter stuff. Still about ten percent out though.

Higher priced and name brand units usually have a little more care taken on part specs which helps.

I had to research speedometer designs 30 years back. Not much has changed though except more electronics involved now. EFI and computer engine management has made it necessary to know vehicle speed which helps newer equipment. I have had to tweak speedometer equipment on a few vehicles.

I had to install a digital(well, I decided for digital) on a barge of a scooter. It was fancy for what it cost. The instructions on how to set things sucked. I posted a big writeup on chinariders.net. I was able to calibrate the speedo to show proper mph using a bit of math. It was NOT a factory part. This shows the speedo embedded in the old cluster.
This is the piglet that got the digital:


There were 13" tires on this 50cc machine. And about 1/2 ton of turquoise plastic... Seating for 2.

I think it had about 800 miles on it, and I put in a BBK to make it at least movable.

 It went off to UGA for use by a tall blonde co-ed.  Spitting image of someone I once dated 50 years ago.

Job well done
