I'm adjusting the float height on a set of BS34SS carbs and found that I need to adjust the tab more then expected. I then noticed that the spring loaded pin is compressing more then expected when the weight of the float is applied. I'm thinking of just replacing the float needle valves (not the seats) but would like some feedback on if I should change them as a pair or not? Don't want to spend the $$$ twice.

Personally, I'd replace everything in pairs/quads. You don't want something fishy going on later and have to take the other carb all apart again.Comment

I'd try needles first. Z1 sells them. You can check effectiveness by measuring fuel level, not just float height. If you use a full tank with the petcock set to prime, it will stress the system and try to force the fuel past the needles. If the needles seal in that situation, you should be good to go.Last edited by Nessism; 05-13-2014, 08:36 AM.Ed
To measure is to know.

Right now, each carb has been tested with a full column of fuel and the float level is correct with no leakage. The only reason I'm thinking of changing the valves out is because I noticed the tabs had to be bent over more then usual to get the correct float height of 22.4mm. When I looked more into it I also noticed that the weight of the floats was compressing the spring tip on the float valve needle and causing the adjustment to be more severe then expected.
I'm going to start the engine with the carbs set the way they are for now but was asking this for future reference. I'm getting my spare GS1000G motor fired up in order to verify it's in good working order before I pull it from the Frankenstein bike's frame. After that it will be a full top end rebuild in order to freshen it up for the transplant into the pretty GS1000G.http://img633.imageshack.us/img633/811/douMvs.jpg
