Hey new guy here again. As mentioned before I go my daughter a Detbi Atlantis Bullet for her b-day?
I took the Bulet out for a test run and found the speedo is off by around 20kph. Now that is a lot. I used my Garmin GPS to verify.
Does anybody know if this can be callibrate?
Thx
Carsten

It is possible to calibrate, anything is possible, but it would not be cheap to have done and probably not easy to do. It can be done, however. You have to disassemble the speeedo and increase/decrease the indicator needle return spring tension to make it more accurate.
The fact it is off, and by quite a bit, is not unusual. They usually read high. The old speedo in my 100 sport would bury the needle flat out. It would actually disappear off the other side for an indicated 140+. Actual speed was 118 kph.
Frankly I would not worry about it. On a stock 50, you just go as fast as you can and, hopefully, flow with the traffic.
