With the standard air box on just the internal mesh removed I have main jets of 115 in all 3 carbs and 45 pilot jets, originally had 47.5 pilots in but it does splutter a little just opening the throttle at 2250 RPM, after a bit of reading and checking my old set of carbs found out the B should have 45's as the need on position 4 rather than position 3
I am about to try to fit the air jets aka anti-surge jets as now getting a bit of surging at lower revs, but the #45 pilots have made it a bit better at 2250 RPM
 Just
sprayed the carburetors in 2 pack etch primer.
|
 Used
2 part brake caliper paint to spray the carb body metallic
silver.
|
 The
mounting bracket is made from solid brass, with mushroom headed
allen bolts holding the carbs on.
|
 The
tick over adjustment screw is made from stainless steel with a
rubber O-ring in groove for grip.
|
 All
the butterfly linkage has been machined off and the ends of the
shafts drilled and tapped. Have had the shafts hard chromed and
the linkage plates decorative chromed. They can easily be unbolted
to re-chromed. Have also used mushroom/button headed allan bolts rather than the standard cap heads shown in photo.

 Sand blasted choke unit, had to mask up the back and made some M10 x 1mm inserts on a m4 bolt to blank threaded hole, and user to connect to earth wire on powder coater.
|
 Made up to blank off choke assembly hole and make the powder coating easier.

|
|
 Powder coated in a metallic silver
(colour Titanium )
|
 Fitted the choke assembly, polished the brass nut and smeared oil on the plunger, also a bit of grease on the oil seal.
|
 The butterfly has been temporarily removed. The vacuum pipe fitting has also been powder coated in

|
 Fitting the butterfly assembly after drilling the M4 holes in the end of the shaft. Using M3 mushroom headed allen bolts to hold in the brass flap. Applied thread lock to the bolts.
|
 The shaft has been tapped M4 and about 15mm deep.
|
 |
 The end plate has been bolted on with stainless steel allen bolt and washer.
|
 Have had machined up some stainless steel carb brackets. They just need a threaded nut welded on the back for throttle cable, and the fingers bent slightly for the other cable.
|
 Holes drilled out to 5.2mm 15 mins with the dremel and a bit of polishing.
|
 Welded a stainless nut on the back for the return cable, and bent up the 2 fingers and polished.
