I guess i'll check the compression.
what is consider the lower limit compression for a 125cc ?

Thank you.

I did some testing today.
All the tests were with the new R/R . (Btw on the package it says "made in taiwan")
I installed the old Lead Acid battery back in the scooter, and i started it with the kick starter because the battery
don't have enough power to start the engine, although the voltage of the battery is 12.5V .
Immediately after the engine started i measured the charging voltage, and i got 14.3v and up to 14.54 when rev up the engine.

Now, i installed again the Lifepo4 battery (which have 13.2v on rest), and i started the scooter, and the
charging voltage i get is 13.3v to 13.35v when rev up the engine.

Are these Lifepo4 cells work different with the charging voltage?

Hi,

Thank you for the quick reply.
I had this even when the battery was new (Lead Acid type) .
Although i think the voltage reached up to 14.3v when rev up the engine.
But it also took a few minutes to get to 14v charging voltage.

Now, i replaced the battery to a Lifepo4 type, which have a voltage of 13.2v when scooter is off.
Even after a 30 minutes ride, the charging voltage is still around 13.5v when rev up the engine.
Is 13.5v is enough?

Thank you.

Hi,

Yes, i can turn the needle by hand and it's very smoothly. the needle also return back to zero smoothly.
I don't know if you can see it in the video, but the outer circular case is spinning not round.

I tried to apply some white grease on the gears (after cleanning the old grease), but it didn't help much.

I can try and disassemble the assembly to get to the magnets, but i don't know how.
Do i need to take off the needle (isn't it going to cause the tension spring to go out of calibration?),
or do i need to disassemble it from bottom where the speedo cable connects to?


Here are some pictures:





Thank you.

Hi,

I'm having a strange problem with the speedometer.
For a while the needle was wobbling at lower speed, so i took out the speedo cable (the inner cable), and i cleaned it
with brake cleanning fluid, and then i lubricated it with grease.
That didn't solve the problem. I also checked the speedometer gear at the front wheel and it's spinning ok.

A few days ago, the speedometer needle started to jump all over the place.
When i'm maybe at 50 Km/h it's showing 100. It even went all over to the end of the scale.
The needle also sometimes get stuck at certain speed when the scooter is stopped.
Sometimes the needle is showing the correct speed (although it wobble).

With all that the odometer is working without a problem.
I guess there is a problem inside the speedometer itself, is it possible to fix it? (a new speedometer is over 100$)
What can get wrong inside?

Many Thanks.
