New 650 exhaust without lambda-what to do?

[Haggishunter]

Hi been a while due to various things but almost finished putting my burger back together. I got a new stainless exhaust but no lambda sensor fitting so left with the 4 cut wires and F1 code showing. Is there a way to cure this by twisting various wires together or what?

Many thanks

In short: NO, weld a boss into the exhaust and put the Lambo back in...the ecu reads resistance changes in two of the wires..It can be done but i know of no one who has put the £'s into doing it on the Burgers, you could try some of the tuning places for bikes they may have a plug=in dongle type thingy to fix it.. Trackday tuners and peeps like that may be able to help..But far more Simples to just fit the Lambo back in, if you need a boss making shout up with thread size of lambo and i will make you one...

Edit: also try exhaust makers they too could have a plug-an-play thingy...

Thanks for all the replies - decided to go the 'plug in route' and ordered an o2 eliminator thing from e bay - shall try and fit it tonight and let you know. Lynn thanks for the offer of making up a boss - wish I had the ability to do things like that but whenever I try to do things like that it all ends up as a mess!

Cheers

Any time HH give me a bell if you need any thing making lathe/mill wise, i have to justify the cst of the kit to myself every now and again
Naaaa! thats a heap of crap i don't

Your fuel economy will plummet with a O2 bypass device as the ECU cannot read the current oxygen level in the exhaust and make the required fuelling changes. With the bypass fitted the system runs on the default mapping with no 'real world' adjustments. It will fool the system into turning off the warning lamp but it will not replicate the function of the lambda sensor. You will effectively be going back to a pre 2007 type engine management system like as was used on the X9 500 where the mapping was fixed rather than flexible.

Do what Lyn recommends and have a sensor boss fitted. It will pay for itself in saved fuel in a short while.

If they did emissions tests at the MOT like cars it would fail without the sensor.

After you done that get a dyno run and set it up propperly to run without a CAT they will re map the ECU or get a power commander, but they are about £300, you will prob get 5-6 more BHP

what do the Power commander do?
i know of a gts 300 with supposedly a power commander fitted its no better than my standard bike

Offer still stands as it's hissing down and i am not going anywhere of interest this weekend
Just tell me the thread size and i will part off a lump of steel drill and thread it and put a bit of a tapper
on one end for the welder. Then just sit it in the hole you drill and weld...all your troubles will be little one's..

There you go an offer too good to refuse.
Power Commanders take money from your wallet and do very little in the way of pay back. On an auto much of what they can do is negated by the lack of being able to fix gear ratios and rev the bollocks off your engine. And no, the Burger semi auto function is not the same thing as a manual gearbox.
A PC simply takes a couple of sensor inputs and tweaks the output to the ECU to fool it into giving a bit more or less fuel in certain areas and to making slightly more radical timing changes so slightly increasing the BHP, or reducing flat spots in some cases. They do very little on a well set up original ECU.
They are best value on bikes which have been neutered to conform to emission or noise regs, and have a resultant flat spot or generally dull response in some rev bands. You would be wiser to shove a few tenners Lyns way than buy a PC.
