Tachometer wont go below 2000 RPM suddenly

Postby Katatonia » Sun May 13, 2018 6:10 am

Anyone in here experienced that? Suddenly during my drive yesterday (and still now) my tachometer wont go below 2000rpm +/-. But as soon as i rev past 2000, it works fine. My one blinker lamp also busted that same day, but i doubt they have any connection..

Are you saying that the actual tachometer itself won't do it, or the engine when running will not go below 2K? If it is the actual tachometer, try spraying just a touch of WD40 where the cable connects (take off the cable and spray into the tach body).

It's just the tachometer, i can put bike idle so low it dies, but tacho still shows 2000 - works fine above 2000 though.

I'll try some slight disassembly and lubing when i get home - thanks!

Found the error, and feel kinda dumb. It was the tiny screw beneath the glass, that had slowly been popping out and was blocking the needle. Disassembled the tachometer, tightened the screw and now all is good again.
