carbs working better, still need tuning!

[Dragon Tamer]

I am with pggg, I would be very surprised to find the actual boot leaking but have seen many leaks at the head or at the carbs. Or as mro has stated, the vacuum caps on the boots may look good and feel tight but will leak if old and hard. These are easy to get, any auto parts store will have them in small variety kits and they are cheap.
The easiest and safest way to find where the leaks are is to warm up the bike, then set it up on the center stand and let it idle. Using a small propane torch (NOT LIT) just open the valve until it hisses. Move the torch tip around each boot until you hear the engine speed up, that will be your leak! DO NOT spray a flammable liquid on a warm or running engine. If you get a backfire and the torch ignites all you have to do is pull it away and turn it off, if you are using a flammable liquid and it ignites there is NO good way to turn it off, ANYTHING that you do from that point on comes under the heading of WRONG.

Gas in oil ?

Have you checked your oil level . Its possible when your float was stuck you might of filled your crank case with gas ! Only takes a min to check, put a stick down the fill hole and then take it out and try to light it with a match if it lights right up you have gas in your oil. Just a thought.
