Yeah, I failed emissions too with the B4 and it took me forever to get the bike into good running order. Ran great when I opened the throttle, but had an idle miss that caused me to fail on the hydrocarbons (only at idle).
So for the few months the bike was out of commission, I commuted with the 15mpg mustang instead of the 42 mpg bike!

Good work on saving the environment Arizona!
I suppose in the long run, it worked out ok because it never did idle well. And I got to learn how to rebuild the Mikunis, balance them, remove/replace them after turning air/fuel screws a half dozen times or so...Hehe. Just chapped my hide a little, cause it only failed at idle, and 90% of my commute is on the freeway...not to mention the fact that it's a freaking 400cc motorcycle!
OK, done ranting. Good luck on getting it all sorted out Solman!
