Help，t120 Black Edition Shakes Really Bad

Hey Fartomany, here’s a super easy way to check the battery: hook up an ammeter in series, then turn off the ignition and see if the reading goes over the norm. Normally, it should stay under around 10-20 mA—I’m estimating that based on a 10AH battery sitting unused for a month. You can also toggle the starter button to compare the ammeter readings, which might help you figure out if the previous owner messed with anything on the bike.

Either way, messing around with bikes is just pure fun!

 

To be precise, after swapping out different MAPs, the bike basically figured out on its own that the crankshaft position was off.
