I wouldn't say replace though I might say enhance as it's supposed to make it more flexible and deliver the proper amount of fuel throughout the power band automatically. You still need to jet it properly to work with the Dial-A-Jet, which is a size or two leaner than you would normally, I believe. I am going to put one on my Amal Mk2 and see how it does. I'll need to get some smaller jets first though. Personally, I'm hoping it might give me more flexibility to run flex fuels but its range may not be enough to cover the difference in jetting requirements between gasoline and ethanol.

I was thinking as I am running an '87 with the bigger jets and now have the Supertrap installed. I should in theory be running just a little lean. I intend to put a K & N airfilter in soon and I believe that would lean it out even more. If I installed the Dial-A-Jet would that compensate for that upgrade. Would it improve performance any or even just make it more efficent.

I've only read about them and spoken with the folks at Thunder Products regarding my specific intended application. I would suggest you give them a call. Very nice folks.

For normal riding in an unchanging environment, I would tend to agree. If your environment changes such that your mixture might be leaner or richer, it is supposed to automagically make up the difference (within limits) and you have a dial to change those ranges for larger changes too. If that's not your situation, I don't see how much it would help anything. Now, maybe if you like to experiment with a lot of different equipment and say... swap mufflers and/or air filters every couple of weeks (for whatever reason), it might save you the trouble of rejetting and retuning regularly. I guess it could also make up the difference if you just ballpark tune it and then lean it up a bit, the dial-a-jet should round it out as needed... provided it works as claimed. It that scenario, it basically an automatic fine-tuning. That's how I understand its functionality anyway... but I'm a just tinkerer.

That was the primary reason I got one in the first place, constantly changing exhaust systems. I find it works quite well, especially when combined with the UFO. That makes a remarkable change in the low range and the DIJ taking care of the rest.
