Reply To: Bad cold start gt125r
Temp Sensor is not available for a 125cc 2016 plate because it doesn’t use “water radiators” .
It has an oil cooler and Korea saw no need to put a sensor on it. However a 250cc cooler is the engine’s favourite investment as it pro-longs its life (Super hot 125 hyos in summer can be moody at times!)
Based on your second reply
- Regulator is shot. Sounds like it’s not charging the battery
- Get a the stator tested though. (Hyosung says if it’s not making minimum 70v AC on all 3 yellow lines, replace it)
(Search on the site “stator” , for old topics to come up , there some multiple replies made on where myself or Simon explains how to test stators)
or
Download on this site GV650/GT650 service manual and “only” follow the section where it says “How to Test Stator Unit” , ignore everything else in the book as that’s for 650cc but 125cc/650cc have the same readings for stators. (Just 650 is bigger that’s all)
