Lambda Sensor wiring

[denny]

So I changed my lambda sensor with one of those £15 ebay jobs, which has eradicated the annoying stalling problem I had. Alls good however after soldering & heat shrinking the sheath, which I assume is heat resistant, was short and didnt cover the cables all the way down to the sensor. Without thinking about it at the time I just wrapped it up using electrical tape and put everything back into place. A mate with more mechanical knowledge than me has told me that the wires should ideally be covered by such a sheath, especially when riding in the heat, ie. Turkish south coast in summer.

I've already clocked about 200kms since fitting without any problems. Should I carry on as is or do I need to take it all off and fit some sort of heat protective sheath, as per the original? I've been given some by an electrician, but it's an arse getting it all off and doing it all over again...

The purpose of the sleeving is to protect the covered wires from abrasion, damage from debris and water etc. it will also protect it from heat, and provide some support to the underlying wires. However, the only part of the lambda probe which should get hot is the bit in the exhaust. The wires routed around the engine casing to the frame and connector, should not get hot enough to melt.

The standard insulation tape, may not last as heat will melt the glue, and it will unravel. if you can, try and get hold of some heat resistant spiral wrap. Easy enough to apply in situ, and will do everything except protect from water. Failing this tywrap the individual wires together as a bundle, this will provide greater support for the wires and help reduce flexing.

While you mate is perfectly correct, provided you have routed the wiring correctly and it's unlikely to flex or chafe. Then it's one of those jobs you could put off until the bike is laid up on a bigger job, like a clutch change or something.

You will get lots of advice one way or the other, and You will have to decide. As you have already done 200k then take a look at the wireing, if you routed it as standard or there any signs of damage or degrading. A visual examination now will help you decide.

Thanks for the reply Ian. I've got a few hours spare this morning so I might rewire it & cover it with some sleeving a pal gave me

Do you have a link for these please?
