O2 Eliminator Mod

Hello folks.

Having ridden a week with my new GSR600 I was already getting fed up with the snatchy throttle. It was the reason I didn’t get the GSR in the first place and I was getting frustrated. However I ordered something called an o2 eliminator before I even had the bike itself. The o2 eliminator is a small plug which you put in place of the cable that runs to the exhaust sensor. I am not entirely sure what it does, but assume it loops the circuit in some way to fool the engine in to thinking that it needs to run rich. Because the snatchy throttle was caused by the engine running lean, the o2 eliminator would remove this problem, or so I hoped anyway.

So on Thursday last week my stuff arrived, forks for my rear paddock stand and the o2 plug. I had ordered bobbins but they were suspiciously not in the parcel.

This is the o2 eliminator, and even though it says “Honda” on the packet, it’s designed for many makes and models of bikes.

So there it is!

I had spoken to my mechanic about getting him to fit it and he said it was easy, but shouldn’t be any more than £30.

But then frustration got the better of me, and on Saturday I decided to try and fit it myself! With a little help of the GSR forum and a bit of wire tracing (from the exhaust to the loom), I found the o2 sensor cable, which looks like this:

So once I had found it, and spent 10 bloody minutes trying to get the plug out of it, I then realised that it wasn’t a push in release, but infact a lift up release….I lifted up the tab and the plug dropped out…idiot.

Then the o2 eliminator clicked in to place. Done!

What I have failed to point out here is that you don’t need to take the tank off to do this. Me being an idiot, I read the forum, seen that the loom was ”to the left side of the tank” and assumed I needed to take the tank off. After doing so and after finding the loom, I realised that I could have easily reached it with the tank on. So dont be an idiot like me, if you look up the gap between the engine and the frame beside the riders peg (LEFT SIDE OF THE BIKE) you will see lots of cables and looms, but there is only one black connector. Then you can easily remove the o2 sensor cable and plug it in. I tested it on my brothers GSR and it was easy!

So there you go! The results??

This is the bike that it should have been from the off. There is a slight lurch when rolling off to 0% throttle and re-introducing it, but all FI bikes do that. It is smooth as you like and it may just be a placebo effect, but it feels like the bike is smoother, more eager and faster. I also read the manual before taking the tank off and found that I can actually do 7k revs and not 6k. Which may have added to the feeling of going faster… But what a difference. I just hope that it doesn’t break my bike, but going from the other folks that have used this method, it seems to be safe as houses. I may even opt for a PC3 if I can afford it…which wont be for a while!!

Then after I had fitted it all, I went out for a short blast to test it. I took some photos along the way.

I did these ones in photoshop at lunchtime today in work. Check me out!

Anyway, that’s that.

Finally the cogs of the Scotland 2008 ride are in motion, having booked the accomodation across Scotland. All we need now is some luggage. I am thinking of soft panniers, so look out for those!!

Thanks for looking folks and I hope you found this post useful!
Cheers
