Feel free to download the instructions off my Ebay ad: http://www.ebay.com.au/sch/7416kevxtx/m.html?item=141644263870&ssPageName=STRK%3AMESELX% 3AIT&rt=nc&_trksid=p2047675.l2562

yes it I've downloaded it, but I figured since your modification was a little more delicate than I thought, already when it is at 5:30 o'clock it has drawn down 30 degrees celcius. just thought if there was anyone who had already tried with the same mods as me before so like the lazy man I am I just need to screw the switch right and drive on without having to do a lot of test runs. but there are no problems, another good reason to ride xt660 little moore!

Thank you kev for everything!
You have made yet another man very happy.

ok, so if I understood this right, Kevs fuel mod will reduce surging,but only a little bit, because of my ECU? (XTR660/2005/ECU-00).

Thanks for answer in advance :)

Have a read here below, I have listed all the ECU's, the fuel mod will help a bit with a 00 ECU but that was a problem ECU: http://www.xt660.com/showthread.php?t=8546

Guys I am having problems with one of my PayPal accounts if anyone wants any mods please can you PM for all sales until I can get it sorted out.

Hello, I have recently made the airbox modification and cleaned my Stage 2 filter, I was out this weekend and drove about 500km and then tried to adjust my fuel mod to get the most effect.
Before airbox mod the bike ran rich if you set it at 6-7 Oclock, Now I had to adjust all the way to the stop at 10 o'clock, then I get the best low and midrange.

What makes my motor need so rich fuel mixture to go well when the description kev has done for Stage 3 air filter will only go to 8 o'clock at most

"Stage 3
air box, set mod between 6 O�clock & 8 O�clock
position."

Or is it just that the low and midrange likes rich and peak hp need it to be lean?

Kev's recommended settings are really just a guide to get you a starting point and only apply at 20C ambient air temperature. Every bike is slightly different, weather affects the way it works and things like fuel vary quite a lot from country to country. It is always best to fine tune fuelling to your bike and local conditions. If you're local average ambient temperature is much below 20C, then you will find you may need to go one or two positions higher than the guide settings for example.

thank you, i am looking in to a PCV instead. putting the kev mod on the mt-03 instead.

+1, Many thanks for your skills and support!

This may be considered a stupid question, but I have searched these forums for several hours and followed multiple links, but I still dont understand how to actually install the Kev Mod. I received the device (rotary controller with two wires coming out of it)when I purchased an 2008 XT660R last week. Both wires are the same colour (green) except one has a male terminal on the end and the other a female. The controller looks like it has been used before as it has velcro on the bottom and a "+" and "-" drawn on the top of the unit in black felt.
So despite viewing various descriptions and looking at various photos, I still have no idea where I actually plug the male and female terminals into. Am I crazy, dumb, or both? Cheers. PS the bike already has a stage 2 filter kit and snorkel removed so I am hoping this is the last piece of the performance puzzle if I can get it working :)
