Hi.
I have a Jonway Ranger 250 scooter with Honda Helix Clone engine. I just wonder why temperature gauge does not rise more than 1/4 of full scale. Radiator fan switch engaged in this temperature. I removed radiator fan switch and do water test. I heated water to 60 C degrees. At this temperature, it switched on. This is so low temperature that cause radiator fan engaged on while I driving. This cause also charging voltage to drop. I found radiator fan switch which engage fan on 88 C degrees.
I checked also carburetor main jet size. It is #102 which cause engine running too hot. Engine run too lean. I think it should be #110 or #115. Spark plug color is clean white. I think repair these problem and get better charging voltage, more engine power with bigger main jet and get engine running in optimal temperature.
Answer is, is that 88 C degrees too high temperature for the Honda Clone engine?
Cheers
