As long as you keep track where each bolt/screw goes by making a drawing of the carb and placing the parts in their spots it shouldn't take you but a half hour to disassemble the carb. You will probably spend more time on getting the carb off than taking it apart.
Both jets should be marked for their proper size. I would say a 42-45 for slow and a 170-180 for the main.
You seem a little hesitant to work on it... if you don't feel comfortable doing it yourself find a friend who has? If you are somewhat mechanically inclined and get the manual you should have no problem.
Hey RKO, thanks for the info and you hit the nail on the head: I'm hesitant to wrench on the carb myself. I have experience working on Jetski (Mikuni) carbs and single barrel stuff on my old truck, but none on the CV-type. To be honest it makes me uncomfortable because I'm concerned that once I take it apart I may change settings that will limit my ability to ride the bike at all, or rather that would require me to have to tow my Sportster back to the dealer.
My game plan is to try the CPS that I ordered (which I know how to replace and can easily tackle in my garage) before I head to the carb. My reasoning is simple: I only paid $26 for the part (and in this case the seller assured me it's returnable should it not work out) and it's an easy fix.
I know that the carb is more than likely the root of the issue and I'll need to take a look at it once the problem reappears (post-CPS replacement). I'll have to bite that bullet and take it off, replace the jets, and then look adjust the settings; call me lazy, I'm just looking for the easiest fix!
Thanks again guys!
