Heading to the DARKSIDE!
Hey everyone, I am doing the upsize on the carb jets to 40 / 140. I am earshaving with UNI filters and I have V&H cruzers. I also have coastered the emissions. I have heard of 2 shims under the needles is the most common. I have also heard of 3 shims and 4 shims... I really only want to have these carbs out this time and get it right so I don't have to pull the carbs back off again. How many should I use? Thanks.
