Successful cat-ectomy - vulnerable lambda sensor.

Ingenious solutions needed!

Fitted my Laser Y-piece at the weekend and re-fitted the lambda sensor. However it's now right in front of the rear wheel, and looks very vulnerable to water ingress and knocks, which will kill the wiring faster than you can say "electrical fault"

Anyone come up with some clever protectors? The best I have come up with so far is a piece of slit garden hose tie-wrapped around the end of the sensor to protect the wires. Anyone done better than that?

Oh, and how high up under the tank is this supposed coil of wire that you unravel to give the sensor extra reach? I looked up and under the tank and couldn't see anything - does the tank need to be lifted? I was stumped at the first hurdle by the bodywork - see other thread

However a bit of cunning re-routing got the bike back to a rideable state.

There is sufficient cable in there but it is cable tied very well to the front subframe.

Undo the two bolts on the side of the tank (You will find it MUCH easier if you use a ball headed allen key on the LHS bolt), pull tank upwards and backwards an inch or two and rest the front 'U' shaped slot on top of the rubber tank spigots (they are the same as the seat supports). You can then raise the rear of the tank and support it with a large mug, brick, or similar on top of the battery.

You will save a lot of time and skinned knuckles this way. On reasembly make sure the fuel cables are not snagged, that the throttle tuns freely, and that the fuel pump can be heard when ignition is switched on. Better to identify that there is a problem now than when all the tupaware is back on.

OK, so you do have to delve well under the tank for the extra cable, thanks

Any ideas about protecting the other end?

Chris,

When I had a Laser Y piece, I tightly wound some self amalgamating tape around the cable where it joins the plug. That seemed to do the job, giving a water tight seal which could stand the heat of the lambda plug.

Cheers,

Paul

OK, I might give that a go! Cheers!

I just wanted to stress what Julian wrote. Make sure the throttle cables run freely after it is all buttoned up. The fuel lines will tend to snag (well...everthing, but at least) the right hand throttle cable and pull the tip out of the socket at the throttle body. If this tip doesn't reseat into the socket, when you start up your pride and joy it will run like a one-legged drunk.
