DIY Kev mod
 

Just like to say a BIG THANK YOU to Kev for thinking up his fuelling mod and posting instructions on how to make one on this site. :notworthy:

I bought all the bits from Maplins. The assistant asked me if I wanted a linear or logarithmic resistor. WTF?? I'll try the first one.
Second problem was the resistor had 3 connectors and I had to solder on 2 wires. A quick look on Google sorted that one (left hand and centre connectors if you want the knob to turn clockwise)

Took a deep breath before cutting the black/blue wire from the temp sensor and 15 mins later it was all connected up, heat shrinked and ready to go.
The resistor I used reduced the temp by 9 C when turned fully clockwise. I marked it at 5 C and took it for a ride.

A definite improvement. Before my throttle was like an on/off switch when the engine was warmed up, now I can roll the power on with little snatching. With the throttle held slightly open there is a very small amount of surging, but nowhere near as bad as it used to be.
It's not a creamy smooth ride, but this is a 660cc single, it's more of a yoghurt with fruity lumps :headbang:

Well worth the effort of making (or buying from Kev) and fitting one.

My bike is an 05 XTX with CCC carbon ovals and standard air filter with the snorkel still fitted.

I will play around with the temp setting over the next few days and will report back. But for now at -5 C I am very pleased.

Nice work mate, glad it all worked out for you.

Holy thread resurrection!
 

I know its YEARS since this was replied too...

But where can i find the DIY mod instructions? I am a dab hand (well thats what i tell myself) at DIY electronics and love the assembly of things as much as my riding.

I suspect i have to be a fully paid up member to access the instructions?

Afraid so. The instruction where freely available once, but we had someone copy Kev's mod and then start selling it themselves for their own gains. As a result we had to drop the information.

Join the supporter's scheme (see my signature) and then contact Kev either through the "Ask Kev" section or by PM.

Thanks :)

PM sent with details.

So its possible to get instructions for a Kev mod? I would also like that. [emoji14] I am a member to.

The fuel mod & O2 controller mods are my own personnel mods which I invented & brought to market & have nothing really to do with the forum, I share some of my mods to try & generate an income to keep the forum alive, with no cash flow the forum would not be here today, that is why we rely on Supporters like yourselves to help us out.

The adjustable fuel mod has gone through 4 updated versions, the instructions were only for the version 1 which used a 1k pot they were remove because of copy rights from past forum members that mass produced them for self gains, so we banned the guys & I removed all the content from the supporters section, the latest version uses a different resistor to accommodate for new mods, if you are a XT660.com supporter PM me if you would like the details of the internals of the fuel mod, there are no step by step procedure for producing your own V4 fuel mod.
