My suggestion: remove the seat and look there for any loose connector, specially those at the CDI module. Will help doing that with the engine running at idle, looking at the RPM indicator while moving the cables: if the RPM needle jumps or becomes alive again, you'll got the point of faulty connection.

Thank you , now i check my model mauel, that lcd display has not have RPM section :(

And manual too diagram not marked any data for tachometer , probably Cdi box unit to not have , :(

But i need a simple RPM clock how i can make that easy way idk , just i think maybe same moto block type same methode measured but my mistake...
