Thread: STX 1100 heat sensor

Between rides the heat sensor corrodes up and the pisser doesnt piss anymore, I can clear it with wire , but it blocks easily again. Any ideas as to whether I should replace it, remove it or other?

I havn't checked on the price of a new sensor but can imagine what they are worth.

cheers

The soleniod is frozen in the fitting, when it first stopped pissing I followed it back and found that was the blockage and it was really blocked at that. I tried unscrewing the solenoid ( I don't think technically it is a solenoid is it? its a thermal switch) but it looked like I would destroy it before it unscrewed. I spent alot of time with wire probing the outlets until it I got some flow , I only cleared a small path and that is why it blocks up easily between rides.

Hi Hog

Same situation as my ZXi. What I did was leave it in a container of CLR and every so often cleaned the ends with wire, then dip it in the CLR again. It took a day to clean it all out with a diluted mix as per the directions. But flows great now.

Hope this helps

Thanks Elusive, as it happens that is what I did this morning to try and free it up a little more.

Hog,

Ditto, except I didn't use CLR, I used Revenge. Most industrial strength.

I sat the entire sensor in a mug of 50/50 diluated revenge until it ate the calcified crap off the outside (~ 1 hr), and the inside of the brass spigots, but it started to eat the metal around the spigots. I then grabbed some clear tubing pieces ~50mm long, placed them over the spigot's and filled the tubes. It only took another hour to eat through the internal's a s well. No problems since.

I also had crap in the line coming from the exhaust header too, and followed the same principle until I have use a wire to push the blockage out. Not a problem since with the sensor. I did test it using a mug of hot water as well. Water needed to be > 90 c (maybe 95 c).
