Here is my restore thread:That looks really sharp! I was toying with doing the same thing to my T140. Did you have to re-jet at all?
It ran rich before with the stock air box on it, so it needed to be rejetted anyway.
As far as jetting..There is a video in the above link of me starting it. It ran very rich so I proceeded to rejet it. Got it running better, but then it was too lean. My throttle valve was too small (3.5) so I ordered a larger one (3.0) only to discover that it wouldn't fit because the body had been bored and If I were to replace the throttle body, it would have to be a special size, which I couldn't find. I went ahead and ordered a new set of the newer Premium Amals. I just put them on tonight and the bike fired right up and idled nice. I wont know about the jetting until tomorrow when I take it down the road and pull the plugs. Sorry you asked, huh?!
