Venom Vader 125cc tach not working

additivewalnut · 10-18-2022, 11:18 PM

All in the title, bought the bike with the big bore kit motor off the frame. Put it on, runs decent, I think it needs a new carb or something bc it feels like it doesn't really have any power and I can't seem to get it to go over 30mph, but I can't tell at what RPM range power falls off. The tach just 100% doesn't work. Nothing shows up on the screen to indicate that it's at 0 rpm or anything, just blank.

Is there a sensor or wire I'm missing or do these just not have functional tachs?
