Wow. Boy I am now in way over my head. ??? Is the idea behind the "dial-a-jet" that it gives you many different jetting options in one? That's what it sounds like to me as a novice but I really have no idea.

The DAJ is adjusted with a screw driver. You have these options...rich, richer, richest. Essentially you adjust, ride, adjust, and ride until it runs good. That is what I've seen another Savage owner do.

I suppose that you can go through the trouble of a dyno setup, but if you do that, then why not just have the carb rejetted normally and save the expense of the DAJ?

According to the website you can make adjustments w/ change in altitude w/o roadside carb disassembly, Nifty.
Dean (Denco) invented it to adjust for corrected altitude on his old drag bikes, so you have to jet the main down two, then the DAJ picks up the slack. So basically you can go up or down one jet. I would like to try one sometime. I will just swap jets for now. If response is flaky I would like to try it. Thunder claims increased mileage, but seems like you would need a too-lean setup to start w/. I would be tempted to lean it out on the highway.

We need this double barrel deal if I am reading this correctly;

P.S. If Denco invented it & Vance & Hines sell them it, must do something. I went back and read the info from their site and I would guess the single DaJ might work good on a stock late model LS650 carb. TP says the main needs to be about two jets small. This is about where I should be now, so would be an easy test to just stick one on when i install the new pipe. It didn't say where is the best location to install the jet? Injectors seem to be moving "up the stack" .Toward the air filter on the LS650.(?) The website shows the carb drilled and the new jet extending toward the center of the airway of the carb throat. Tongue

The newer Savages are 4 main sizes down from the original ones, but of course, the other jets are changed too.

What about the need to have the main 2 sizes smaller? Relative to what? And if you need to change the main jet to use the DAJ, then why bother?

Relative to the optimum jet for your bike.
This thing only fattens the mixture so you go down 2 jets and it can bring you back to where you were or more w/ a little screwdriver. Sounds good for roadside mixture change in the Rockys. says it can correct for up to 12k ft. Check it out on the Thunder Products page.

Don't know about you, but when I ride the mountains the last thing on my mind is stopping to mess with the carb so that I can change it again at lower altitudes. The whole dial-a-jet thing is anal-retentive nonsense.

I thought that "uncluttered" and "simple' were parts of the attraction for a Savage. I've only ridden my bike to an altitude of 6K, but still there were no problems.
