I rebuilt the carbs on my 2001 gp1200r, and was surprised to find they had no high and low speed mixture control screws, just blocked off ports, marked H and L. The carb kit included o rings for the screws, and showed the screws on the schematic, but no screws on the carb. What gives? Also, for $50 a kit, you'd think micuni could include a welch plug replacement so you could remove the one on the carb and clean below it, my $9 rebuild kit for my husky chainsaw included the welch plugs, pretty lame
