    Question about pods and carb on 450

    Ok, so I have an 81 450L. I have some plans for it over the winter, and one of them is giving it a "naked" look. I wanted to remove the air box and put on pods, as well as relocating the electrical components normally under the side panel to where the air box used to be. But reading somewhere in these forums, someone asked if putting pods on a 450 was a good idea, and if I recall correctly, everyone was pretty much against it (restrict too much air flow, lower performance, etc). Despite these drawbacks, I still want the pods. If I were to go through with it (which would still be months from now), what exactly would I have to do with the carburetor to get it running well? I keep reading about re-jetting and dyna jet kits and all sorts of fancy words when it comes to adjusting the carbs for new air filters/exhausts. What exactly is re-jetting? Are there guides to this? Is it really complicated? And would I (theoretically) get decent performance out of the 450 with pods if I did this to my carbs?

    Sorry for the long-winded question

    You'll need to shim the jet needle and go up four sizes on the main jet.

      Hi, if a standard jet in my 450 is 115 what number is 4 sizes up? I have pods on and a chopped exhaust on my 82 450t, now hard tailed into a bobber. I love it, but need to richen the carb.

        Ok, I'm going to sound like an idiot, but I don't really know what that means You gotta remember I'm still new to the world of carburetors.

          Sorry, my question was aimed at the guy who told you to shim your needle and go up 4 sizes of main jet. I also moved my electrics internally and have got pod filters to fit, they incease air flow which is why we need bigger jets etc. Darren.

            Hi,

            The stock jets are numbered in increments of 2.5. Four sizes up from 115 would be 125.

            In order to cut down on the confusion and to be polite to the original poster, it's always best to start your own thread.

            Thank you for your indulgence,

              Hi,

              Check out the information I've gathered on my website. For example:

                Have you put the pods on yet? Did you get it tuned and running?
