. It has completely cured the fueling problem. My bike is now smooth through town and has a good smooth roll of power. I dont think it has increased the power output but it was not advertised to do that.

A fuelling device is used to correct the A/F ratio, it is not a HP mod, it offers the least HP gain of all the mods by it's self. Add a fuelling device to the combination of other mods & you will see big HP gains, a fuelling device corrects the A/F ratio to get the most HP out of all the added mods.

In the past we have discussed the differences between the Nitro X & the Kev Fuel Mod, here is one of the past Posts.

So in your opinion Kev, would there be much benifit to me with stage 1 and 2 filters and mtc cans?

I have Your fuel mod fitted now, would this be better?

The end result would be similar.

I bet they would not show you the insides of their mod & tell how to make your own if you have the skills. In the end it is up to the buyer, they are running a business trying to make money out of their mods, I am trying to help by offering the cheapest mods possible to riders.
