Is anybody changed their gas tank petcock carburetors to gravity feed type?
If yes what did you go with? I'm thinking about trying to find an old 550 or 750 4 cylinder carburetors
 
you just need to block off the vacuum port on the carbs, then you can use any petcock you like. no need to change carbs.
 
Not exactly true the needles in these carburetors won't stop the fuel flow
 
If your needles don't stop flow replace them. You already have a gravity feed fuel tap , it just uses vacuum to open and close it so that it does not flood past the needles in the carbs while sitting. Even on the old bikes you had to turn the fuel on and off manually or you would have the same problems. All that the vacuum fuel tap does is make it easier for you , as in you don't have to remember to turn the fuel off.

Actually, they will if properly maintained and cleaned. I have left mine on PRI for 24 hours or more with no leaking.
Not what you want to do, but proof that they do stop the flow if properly maintained.

I don't like the carb setup on these things, I like the old fashioned carbs that have always been dependable. I have had nothing but trouble out of both of these bikes and would rather have systems I'm familiar with. I'd actually like to get rid of both of these pos's & get a CB anything.
 
Cause CBs are way better at pulling wheelies and ****ing with people in SUVs.
 
I really don't see the attraction to these bikes, I just seen a really nice all original GS550l about same year as mine listed on CL for $2500 it sold but not sure for actual selling price. A Honda of that quality would go for 10 grand.
 
Pretty much been a troll since you arrived too. Do yourself a favor and sell those poor GS's to someone who cares about them and buy an over priced Honda. Everyone will then be HAPPY!:p

Funny how peoples perceptions are. Disagreeing with someones opinion is not being a troll. Baiting someone with unnecessary remarks is.

Recently a 76 550 four Supersport was at $8000 on eBay. Don't know the final price.
 
I owned a 77 Honda 550SS. Not really that great of a bike compared to my current Suzi. I also owned a 79 GS1000 I purchased new. Sure wish I still had that bike.:(
 
I owned a 76 bought new in 77. Paid $1556.40 forit.
Next bike was the 78 Kawasaki Z1R
Then a 1980 Kawasaki Z1R
Love those three bikes
