I'm at a Uni Filter with both ends of the box opened & drilled, 130 jets, & stock needles with no shims. Home base is around 800 feet altitude, with my customary operating area at 0 to 1,000 feet. To the best of my understanding by Pat's app & some other posts, I may do well to drill the carb slides, and throw in some shims under the stock carb needles for an 05 Speedmaster.
I wonder how many or how thick of a carb needle shim to use? I'm not allergic to going over to the hardware store and buying some little stainless washers to approximate the desired thickness. From looking at the carb schematics and considering the result, a few thousandths of needle lift this way or that way may not be discernible anyway. I don't know. I didn't find what I'm asking in a search.
(Alms for the search impaired may be mailed to: me.)
I admit to some concern over running too hot by running too lean, but perhaps that's not an issue. I'm not clear on that.
