fuel wont flow when on prime so i disconnected my vacuum from the carbs and acted as the primer bike started up 5 mins later without an issue minus my idle going up and down between 1500-2000

So? I need new carbs either way?

Dude, start you own thread if you want answers. Stop hijacking the OP's thread.

Intake boots leaking? I have that problem with my 90 1100. Also I cannot find replacment boots. 1990 1100 katana needs intake boots.

Do you happen to know the best jet size combination to use in the 34mm carbs on the 1990 katana 1100?

The 1100 uses 34mm carbs ? Huh , the 1127R engine uses the same 36mm that the 750 does . Wonder what would happen if the BST36SS's were stuck in the 1100F ...

The GSX1100G uses BST36SS carbs too. Just the GSX1100F uses the BST34SS carbs. I find the design of the BST34SS carbs really bad, I'd rather use the BST36SS carbs. The 1100F certainly has a large enough bore to use 36mm carbs. Cheriff is running BST36SS carbs on an 1100F engine.
