    Hi Folks

    My Qingqi Supermotard 200cc has a tachometer that indicates more revs than real.
    Itīs weird couse doesn't happen all the times. Sometimes its ok.

    I Know this couse in 5th gear at 6500 rpm the speedometer show 100km/h but the other day was at 5th and 100km/h and the tachometer shows 10 000 rpm. I stop an at idle shows 3500 rpm

    What can be wrong?

    Anything else seems to work OK. I made a 1200km trip this week (semana santa) with no problem besides the tach.

    Im sure this is not good. But can't figure it out.

    Thanks in advance

    Qingqi 200 Supermotard. (Genesis) Mods Until now:Rised Handelbar with stock risers and a lot of washers. Almost 10cm. Pillion handles eliminated and enduro model rack puted in place with turn signals just ziptied to it. Abominable Top Box over rack! Kickstarter removed for comfort (now inside TopBox). PCV pipe bolted to subframe holding my tools. Acerbis supermoto handlebar protector. Turnsignals bolted to the Abominable Top Box base.

    Hi there..
    I think that is a problem with the cable that measures the rpm's... You can change that cable and see if there a change is made.

    If you don't know where the cable is located, give me a feedback and i will show you a photo.
    Cheers!

    Those tachs units are known to be fidgety. If you haven't been playing around with the wiring, then it's probably just the unit. I've seen that model tach on a couple other bikes so I'm not sure if it's an adjustable unit.

    would i be right in thinking that these units take their readings from the coil? if thats the case then if there are no running problems then yes it could just be a faulty tacho.
