Well the fittings on the flat top Bings have scuppered my manometer project the thread is too fine to adapt on the take off points i bought some spare screws and tried to drill a fine hole and weld a tube adaptor but they are too small and i still cannot figure out what the thread is.The good news is however i seem to have her running pretty sweet i set the air screws at 3/4 open then backed of the throttle cable set a 5 thou gap on the throttle stop adjusted the cables to 6 thou on the stop and he presto sweet as a nut, i would recommend this method for anyone with flat top Bings or anyone who has no manometer

A bit cruder but I usually force the plastic tubing OVER the nipple and secure it in place with a twist of wire. YMMV

Here's my homemade apparatus for setting the throttles to open at the same time. I use it when I can't be bothered getting the manometer out or as an initial setting before using the manometer.
"Borrow" a pair of your wife's finest Knitting needles, thinner and lighter the better. Cut a pair of short rubber tubes about 3/16" id and pierce one end with the needles. Push the tubes onto the exposed inside end of the Carb throttle shaft. With the right tube they hold in place quite firmly.
With the needles arranged either side of the tank you can observe that the throttles open at the same time. The 16" long needles amplify the slightest rotation of the throttle shaft so it's a very sensitive method of mechanically balancing the Carbs.
Being a sad old thing I calculated that 1 degree of rotation results in over 1/4" of movement at the needle tip. In practice you can observe a much smaller movement than this, say 1/10th of a degree or approx .002" at the edge of the throttle disc.
....and if your not into Knitting Lou I find that my 3/16" id manometer tube is a good tight fit on flat top vacuum take off points.(http://)

Anyone else notice how CLEAN Barry's R45 is?
Between Scotty in Marble Falls and English Barry I'd be embarrassed to ride with them. How about y'all? Follow along about a mile behind, I would. And what's up with that floor? I can even see the bike's reflection.
Very impressive, Barry [smiley=thumbsup.gif] I need to make a list...

Guy's I think your ribb'n me about having a clean bike.
I do use it you know. I swear it's been out 7 times since I last cleaned it.
In fact I was out last night with guy I grew up with that I haven't seen for 20+ years. He turned up on a 900 Ducati Monster. He's put 77,000 miles on it and has 4 other bikes as well. I was proud he turned out right.
