[quote=mnb;140811]How much would You Kev recommend to lower the air temperature on '07 model with aftermarket exhausts, removed snorkel and drilled holes ? You can go as low as -20 from the actual dash reading.

What are (in general) possible side effects of using this mod - instead of powercommander or similar ? No side effects at all, with a 100% proven track record over 4 years. A Power Commander is always my recommended fuelling device, with a custom made fuel map if you have the funds.

How can one tell if his bike is tunned well with this mod ? By reading the spark plug ? If so, how long has the bike to be ridden, and in what mode.
All the adjusting information is on the disk that comes with the fuel mod. Otherwise adjust the mod to find the smoothest ride if you made your own.

hi kev im mario and i own an xt660x 2007 model. previos owner have fitted the fuel mod but still surging a little bit on low revs maybe it because it has a high speed gear box if i change front sproket will it help make it a bit smaller

Hi Mario

My fuel mod will increase the fueling, with my fuel mod fitted to a 2007 XT660 > with O2 sensor it will reduce the surging but not eliminate it, you need to control the O2 sensor as well to get rid of the surging.

To eliminate the surging on 2007 XTX XTR > you need to fit Dynojets PCV + O2 Optimizer or one of my fuel mods + one of my O2 eliminators. If you want to make your own O2 eliminator I explain how to do it & where to buy the parts from in the latest version of my mod book.

A few other things to look at are worn rear sprocket rubbers & incorrectly adjust chain or worn chain & sprockets, also do my twist grip mod this will help with small throttle openings.

All that type of info is found in the ASK Kev section or in my mod book, my mod book explains how to make my O2 eliminator in detail & where to buy the parts from, a plain resistor does not work as a O2 eliminator there is more to the mod which connects to the cooling system.

Clutch lever sensor mod ???
 
I herd from a Yamaha Mechainic that the clutch lever sensor wires can be bridged for a gain in acceleration or power responce ???

Sounds a bit odd.
Perhaps someone with a dyno acn look into it ???

Unless folk get hung up on the surging I wouldn't bother with a PC,I went from the Kev mod to a PC,yea sure the surging has gone andthe bike is marginally quicker but I wouldn't want to have to live on the difference,so unless you can get a secondhand one of ebay,save your money.

Hi there you can buy it at this link: http://www.xt660.com/site/node/136

scroll to the bottom of the page and click on the PayPal icon, once you are in the paypal website, there is a box when you can live a note and in that box please give Kev the exact model and year of manufacture and he will ship the correct mod to you.

All Kev Mods come are now very plug and play, with no soldering required, you get a step by step guide on how to fit them and how to tune the fuelling knob.
