Sputters and dies

[lukemuggy]

Hello all,

I have a 1990 Katana 750. My problem is that when I am stopped at a light, or even when I put in the clutch for more than a couple seconds, my bike will die.

I have tried revving it up to clean out carbs, and I adjusted Idle screw. But after a day, the problem was back.

I have two inline fuel filters, but they appear clear.

Any help?

My guess would be the idle jets need cleaning ....
Try seafoam thru a couple of tanks first to see if that helps before tearing the carbs down ~

seafoam....* & lucas
either or.... will only help to use both
Mine did the same i think.

atleast mine would sputter and wouldnt wanna go over 2-3-4k rpms put lucas in it and let it warm up now its better

but still sometimes bogs... Probably my sparkplugs

someone told me..... if it doesnt idle right like yours & mine doesnt...
then the jets needs to be cleaned/

carbs cleaned/ jets taken out and soaked over night
