float heights

[thrang]

After reading what people said about fitting the independent floats (I'll save them for my other set of carbs) I opted to get some std Bing floats. Just a quick question does anyone know what the gap between the float chassis and the lifting flap is. Basically I am feeling lazy and if some knows what it should be then I can set the float to roughly the right point before I install them. I have a history of trashing the float pins and even though I got a spare sods law says I will bugger up a new pair of pins if I need to remove them to set the float to needle gap again! I know people say you can do it on the bike but I've always made a total fu*k up of it when I try. Cheers T.

The way I've seen in manuals for adjusting float height, is to turn the carb upside down and adjust the tang, to where the float is parallel to the body of the carb .

I installed the independent float kit on my '81 R65 back in 1997, I really don't think it was worth the effort or cost to do this .

One part that Bing had, was molded plastic floats, but they discontinued this part a few years ago .

I think changing the floats every 4-5 years, or better yet, weigh a new set of floats and then take them off every few years, weigh them and see if they have absorbed any fuel and have become heavier .

That's the way I've always done it in the past Bob, but I was kind of hoping someone would have a measurement for all new internals. The main reason for asking is I have just done a 1200 bandit for a mate and the Suzi manual had a gap measurement unlike the Haynes and Clymer ones I have for the R65.

There is no official figure and I've never seen such a measurement in print.  If it's any help my recently installed new floats needed the tab opening up a little to get them set right.  

How about finding a substitute temporary pin perhaps marginally smaller in diameter than the proper pin.

If anyone is interested, when I set the Bimbo up the float height was 3mm at the between the base of the float chassis and the top of the tang at its highest point, this was with all new internals. Happy days she fired first time and after a little twiddling with the idles she's running sweet as a nut.
