Bike tachometer problem

[HardDriver]

Hi, my bike is suzuki rg 125. I take away motorcycle to repair shop, they said that bike is reving more than 7000 rpm, but that the arror(indicator) is not moving more than 7000 rpm, but engine is having more...

SOOO, said that cleaned connections to speedometer. So they guessing that something broke in tachometer? But what could be that?

Maybe I need to assembly tachometer and maybe wipe out? I don't know need your help guys, because my bike isn't going as should to I think, and I can't see how much revs he past, so it's a big problem to my.

If it's driven mechanically then the cable may be worn at the gearbox end There might be something you can tighten. If it's electrical then the sender (gearbox end) is probably broken.

How that sender looks? Not this bike exactly?

Do you have a friend with the same bike? If so stand them together and rev them and see if they sound the same and clock readings are the same.

No, yesterday I drived a lot so in 3 or 4 gear I reached limiter but the rpm shoved just 8000 or 8200 I think... So definitely it's something wrong that doesn't show high rpms.. I will look in rpm cable all the way, but what about that sender, I'm new to that, how it looks?

OR, its two types? One is electric sender and another rpm cable? If I understanding okey? Then mine would be rpm cable I think. Could be useful if someone who had suzuki rg 125 comment here.
