session: I've got a 2001 TLR with similar problems. I've got the same V&H pipes too!
And I have noticed the same "rich smell" you're talking about.
I'm hoping a local mechanic can "flash" the ECU with a Yosh Box. I've already put new plugs in it. But just normal NGK's.
Right now, I'm just trying to make sure I do the airbox mod and TB sync the right way.
Looking forward to seeing how your project comes along...
