I got a carb rebuild kit and it didn't come with a Main Jet Holder. I tried, without success, to separate the main jet from the holder only to mess one up pretty good. Were can I get new "holders" or is there a trick to separating them? Carolina cycle said Honda is no longer supplying them. Additionally, should I use 105 with stock exhaust and air pods...or go to a 107, 110. It idles perfectly with stock setup. Losses all it's wind above 4,000 rpm. thanks!!!
