hi
In a recent ebay frenzy, i purchased this

http://www.ebay.co.uk/itm/3218259924...%3AMEBIDX%3AIT

It is Kev mod and 02 controller but im not sure if i can put on my bike... shoulda checked.

it has 66391236 on the controller but no other information.....

can i fit this? or is it for a different bike altogether?

Purchased as since fitting metal mule exhaust it to see if it calms the new surging it seems to have......

any help as always

You should be OK with the Dynojet O2 optimizer and that appears to be a genuine Kev mod, not a copy/DIY job. What colour knob is on the dial? If you have a multimeter you could check the range of resistance the Kev mod gives to give an idea of what version it is.

Thanks guys, ill let you know how it goes on

Nethen, let us know how it goes please.

Kev,

My 660r is awful, surging and popping and banging on overrun. it has a PC fitted and a 2-1 with a scorpion silencer..will your mod sort this out please ?.

Kev's mod will not help you if you have a PC fitted. What map are you running? Is it a custom map, or one downloaded from somewhere? A custom map may help. What year is your XTR?

In the meantime have a read of this thread and the links within it. Should give you some ideas to help with the surging.

The popping and banging is easily fixed by blocking the AIS - read this thread.

I dont know which map, i bought the bike with it already fitted. 2007 bike.

I will check the AIS pipe and get the PC map checked... Thanks.
