Hello all, i have a problem with my ATV. Can you please help me?

When i drive my ATV and it heats 4/6 lines, the EFI led turns on. I don't know why is it happening. the thing is that the ATV works as normal.

Is it a normal error or is iti something that i have to worry?

when the engione goes to normal temperature, the led stops.

It is a 2016 Cf Moto 450s.

It's overheating. Three bars is the norm. Check that the fan is coming on at 4 bars. If not check if the fan switch has failed. Overheating is the #1 cause of death for these..and most other engines so don't let it get higher then 4 bars.

The fan starts at 3 bars... i really don't understaund why the ATV overheats... should i put another fan beside the original one?

The ATV is heating at 5 bars i think... i will check this and come back whit a reply.

Thank you!

Is the rad plugged, the fan coming on @ 3 bars is good.....does it stay on while the bars are going up?

the fan works very well but yesterday i observed that the radiator grooves are bended. this might be the cause i think!

Problem solved!!

The radiator was full of mud on the backside.

Thank you all for youre help!!

Sounds like you need more time in the jet wash
