a55 idle jetting question

Michael Smithes /

I recently upgraded from the stock 14mm carb on my a55 Streetmate to a 17.5mm carb. I upjetted the main jet of course, but I'm not sure if I should or if I need to upjet the idle jet. Right now I'm using the 38 idle jet that came with the carb. It idles ok, but it gets boggy when I accelerate. I know I probably should upjet the idle, but I'm not sure what size to move up to. I was thinking of jumping two sizes to a 42, but maybe just a 40. I realize I could get both, but I'm looking for input.
