Hello I recently bought a Kumirin G4 scooter used and I have a few issues with it

•It some times shows that I’m going slower than I am

My thought was that the wheel diameter is set to a wrong size but I can’t find a menu to change that

•It only goes 60km/h (should go 70-75)

I don’t know why the police mode isn’t turned on and it is in race mode

•The throttle button is aftermarket

The previous owner installed a different one (the original has the throttle and an off on button the new one has just the throttle) so I can’t activate the police mode if I wanted to and i don’t know if I need this button to get into the settings menu (if there even is one)

•I can’t find the app to connect Bluetooth

This one is not as important but it is good to have

I’m on a newer iPhone maybe someone could tell me an app that actually works for the g4 or send me a link

Maybe someone has some tips for me would be very nice

Hey guys I bought a scooter for restoration and I’m completely clueless about that problem, that scooter I bought is a CPI Hussar JR 50 from 2002.

The CPI stood still for like 2 years I think, so as it, was the complete Fuel system rusty bec of the metal fuel tank.

So today I cleaned the whole system up. Old rusty fuel out setted a new fuel filter between that tank and the carburetor and new fresh fuel in. The sparkplug is completely black, so in that process I also cleaned that one too (new one is coming soon)

I changed the intake manifold to a new one and I changed the membrane block aswell because everything was dirty, rusty and porous.

For now I didn’t check the engine yet, tomorrow I will do a compression test and take the head apart to take a look at the inside.

Maybe someone knows something more about that problem.

Thank you guys for ur help!
