"One hump or two", I like that :)

Excellent, we're probably on the right track so.

Which is why I thought my throttle setup was so weird. More twist should equal more power AFAIK.

Actually, I did that last year. When my air filter box lid was stolen, I replaced it and first began noticing a flat spot. The shop suggested that test, and when tried, the machine took off down the street. Was only a short test however, no more than 150-200 metres. I've still got "fiddly" throttling to this day. Then again, it had only been derestricted a short while before the theft, so it may have had the same "spot" before as after.
It's my plan to replace the entire air box before I do too much fiddling, remove the filter "variable", so to speak Even so, the fact that Suzukis' own manual has no other model of this machine with such a big main jet is telling. Perhaps the dealer fiddled with it when he installed the carb heater....

I'll start looking into that.

Need to avoid that! This thing is my ticket to work. Otherwise it's out of bed at 5:30am to arrive in work at 7:45amshudder, as opposed to getting up at 7:00!! Did that for 3 years, don't wanna do it again....

Nice idea, a "filter press" of sorts :) I've just cleaned/reoiled, so I'll be sure to check I didn't overdo it.
Thanks to everyone for their ongoing help BTW, I usually don't get replies on Usenet, or the enjoyable conversation!
