Morning all.

Please cna somebody very simply and quickly explain what the mods are and what the effect is.

I have a bog standard tenere and might have a play with it but i do not want to mess up the MPG in any way as i use it everyday for a long commute.

I get a lot of surging when cruising around 4k and wonder if a mod will fix it?

I have tried to go the the Kev mods section on this site and it says i am not allowed.

Any ideas please.

Mike

I have a few mods Mike.

Fuel mod: adjusts the A/F ratio in the open loop mapping, can be used to correct the lean mapping on a standard bike or with DNA 1 to 3 filters or all filters + pipes.

O2 controller: maps the closed loop circuit, most effective mod for low rpm control for 2007 onwards XT660's, eliminates most of the surging caused by the O2 sensors emission control mapping.

I would recommend both mods to map the bike correctly to get the best results, if money is a problem I would start with the O2 controller + twist grip mod for your surging.

Fuel mod http://www.xt660.com/site/node/136

Fuel + O2 controller, can be bought by PM from a discounted Ebay price, or from EBay if you really want to pay more.

O2 controller same as above cheaper via PM.

Hi Mike,

I've just installed the two Kev Mods to my Ten, you can read about them here:
http://www.xt660.com/showthread.php?t=21137

In short, the single greatest thing you can do for your bike is to install the O2 sensor mod. Will smooth out all your low-end.

The next step will be to swap the air filter and cover, let a lot more air in.
For this, you'll need the Kev Fuel Mod so you can adjust the A/F mix properly.

Then, you'll want to do something with the exhaust to let all that gas out again!

Follow that with the cush drive rubber mod and a properly tensioned chain, and you'll have yourself a bike that can tickle along at 30mph but responds properly to acceleration, roars through the gears and doesn't stop pulling til about 115mph!

Estimated increase of about 6 bhp... and I only spent about �200... Beautiful!

Hope this helps,

Steve.
