o.k. more progress, but now I really have to call it a night...always how it goes right?  Couldn't help but see if anything was ready to move, after all it been soaking for way over 2 minutes now! ADD jokes anyone?  Replaced the threads and tap tap tap.

Yippie!...  now just give it a good soaking and get yerself a new main jet...

Depending on location and mods,... you may want to go with a bigger size?...
You will be looking for a "Large, round, Mikuni, main jet"...
#145 is stock size,... tends to be a little lean for most bikes at sea level...

Remember to install the washer under the main jet... it's important...
