I'd pull the petcock first, and look for some clogging on the pick-up tubes... (just 'cause it's easier to check)....
With 102 posts.. either we suck... or you have a very unusual problem...
... but we're stubborn... don't give up...
At this point,.. we absolutely must find out what's going on...
We're with you in spirit...

PS... if it's neither of those...(... and I don't have time to read back over all 102 previous posts)...
I'd start looking for an electrical, overheating component...
JMHO...
Best of luck...

Well, about the crack in the float i didn't find any visible one, and when i tested the float for leaks at the beginning of this "Odissey" i drawned the float in a glass of water for almost an hour meanwhile i was doing other things at the bike and it seemed just fine, no bubbles, no water spilling out the float when shaking... i' more inclined in the second option, as i have put a fuel filter between the petcock and the carb... but listening to many this problem it's related more to an abundance of fuel and not lack of it...
Anyway, it seems to run a little bit better and moreover it's about 55 miles since the last spark plug cleaning and it seems holding... finger crossed.
I will put few more miles to it as soon as i resolve a fresh new problem with the rear direction lights, but this is another story...
As for the forum, i love this forum and i really appreciate the support and the will to help of all of you guys, this forum doesn't suck at all, IT ROCKS!
Probably it's just a particularly difficult case, with a bike almost twenty years old and six previous owners with lack of skills probably even worst than mine, and a current owner (me) that it's not a really experienced wrench...
Anyway i will keep an update to the let you all know if the story has an happy ending (gosh i love happy ending)
