I don't know if this is relevant but I had something similar inasmuch as coolant being forced out of the bike all over my leg with a RD350 YPVS this apparently was due to a cylinder head gasket failure,  I assume somehow this had pressurised the cooling system. I know that you have had a major rebuild but was the head checked to make sure it wasn't warped at all before it went back together?


this could very well be what's causing the problem. we tried idling with the radiator cap off, and every once in a while we saw a few air bubbles making their way up. mechanic said he'll remove and check the head for warping.


still doesnt address why my water temp isnt showing on the multi gauge though

I can't remember where in relation to the thermostat hot side the Temperature sensor is but it sounds like that either the Thermostat is not opening or there is a massive air lock in the system preventing hot coolant getting to the temperature sensor and thus the reason the fan is not kicking in is it is relying on surrounding parts getting hot and not the flow of hot coolant over it.

Worst case scenario is water pump failure, thus not pumping hot coolant around the system and  past the temperature sensor.


thermostat is new too, but i think your explanation about the fan waiting for surrounding heat transfer makes sense

Some photos of my bike at overhaul. There was a bloody leaf in the intake valves I got done pretty bad by the previous owner

Hi all

My fan kicks in extremely late and I'm wondering where to start troubleshooting. I've changed the thermo sensor thrice in the past 6 months to no avail. Right now I'm riding with a direct current to the fan, so it's permanently running.

Fyi I'm riding in tropical Singapore and a couple nights ago I was caught in a traffic snarl the fan didn't run when it should, the coolant reservoir cap just blew out and some boiling coolant scalded my right thigh. The problem doesn't seem to recur once I had the fan permanently on.

Almost everything else is new. I just had the engine overhauled and the main wire harness changed last October. Even my fan relay is brand new. I'm also running Christian's multi gauge but the water temp reading is just missing (shows a dash or hyphen).

Any ideas? Is it possible the thermo sensor wire needs replacement? Could the fan possibly be waiting for a Fahrenheit reading (high!) from a Celsius sensor?

Thanks in advance!

What kind of meter is it, and where did u get it ? Thanks


It's Christian's multi gauge. I got it from him.

I think he is talking about the over temp light just to the right of the clock (am/pm one)


That never comes on at all.

hahaha... i'm happy here in the tropics!

the fan comes on when:

1 - about 3 to 4 minutes after the bike is warmed up from a cold start, and stops once i engage gear 1;
2 - sometimes when stuck in traffic at a light.

i will double check the gauge when i have the time to remove the inner panels and the instrument cluster. possibly in the next few days.

tex, what light are you talking about? i removed the filament bulbs that provided the back lighting, and installed a white LED strip. Here's a video. https://youtu.be/HwQzhbcMuWc

Hi fellow foccers


I recently installed the multi-gauge (amazing work - thanks Christian!) and observed a problem with the water temperature readout. It is permanently showing a dash <-> and this means that the reading is either too high or too low. Given that I've tried waiting from a cold start until my coolant started to boil, I guess this suggests my water temp sensor is not working. This can explain why my engine runs hotter than any other FZS1000 rider I know! When caught in a traffic snarl for only 10 minutes the coolant starts to overflow via the hoses below the right footpeg.


Would any of you foccers happen to know from which OEM part category this sensor is found and what is the name of the part? I've been thru the entire parts catalogue and could not figure out where it is. The water temp electrical signal to the dashboard must originate from somewhere on the bike itself, right?


Thanks in advance mates!
