Carbuerator Pictures (*.jpg) Parts  - Page 4

1997 Canadian Vmax JYA2LTN

These pictures were taken to help me re-assemble.  Some part names had to be invented.
Bob Walsh VMOA 2469
fuelline.jpg (68160 bytes) Fuelline - the relative positioning of the hoses that join the carburetors.  Note that the black hose is longer on one side than the other.
PAJ1.jpg (36985 bytes) PAJ1, PAJ1a - the same jets, two pictures.
PAJ1a.jpg (38233 bytes) PAJ1, PAJ1a - the same jets, two pictures.
piston1.jpg (46255 bytes) Piston1 - the piston valve relative to it's chamber.  On the bar to the left is the o-ring from the lower left of the chamber rim. On the bar to the right are PAJ2 and the idle screw.  The piston valve spring goes into the hollow of the piston valve, as at the bottom of this picture.  (It was omitted from the picture because it made the other parts look too small, IMHO.)  Piston valve diaphragms - these may be stuck to the carb body but can be loosened similar to the coasting enrichment diaphragms but first gently push the needle in the carb throat towards the piston valve until the diaphragm is in its natural "umbrella" shape.  See piston1, 2 & 3.jpg.  Use your fingers to hold the diaphragm ring and loosen as per coasting enrichment diaphragms.
piston2.jpg (38349 bytes) Piston2 - The piston valve parts disassembled in relative orientation to each other.  The needle drops point first into the diaphragm end with the orange ring.  There is a small alignment pin on the ring around the needle that must fit into it's hole in the piston valve before the washer, spring and screw are dropped in (in that order) or you will not be able to start the screw in it's hole and even then it's an exercise in patience.  Actually only the spring will fairly easily "drop in".  The washer and screw require a light touch and some coaxing.
piston3.jpg (36029 bytes) Piston3 - A different shot of the diaphragm to show the tab that must be aligned for proper fitment of the diaphragm to the piston valve chamber.  This is very easy to do if the diaphragm is positioned as shown in piston1, 2 and 3.jpg, in it's natural "umbrella" shape, and kept that way by holding the needle in the carburetor throat with two fingers while compressing the piston valve spring with the piston valve chamber cover with the other.  Ensure the piston valve spring is outside all 3 legs in the center of the chamber cover.  Once the cover is in position you can let the needle slide into position.
starter1.jpg (51515 bytes) Starter1 - the starter plunger assembly and relative to it's position on the carb. The starter plunger rods and levers (not seen here, see carbsup & down pics) go in the front first (carbs 2 & 4) through to the back, with the "choke" lever by #2.  The starter levers are slid on as you push the rods in.  Note that #2 is different, see starterpuller.jpg and notes.  Make sure the bushings are in place also, see startershaftbushings pic and notes.
starter2.jpg (52264 bytes) Starter2 - the plunger itself disassembled.
starter3.jpg (33581 bytes) Starter3 - a close-up of these parts.
starterpuller.jpg (27467 bytes) Starterpuller - the levers that pull on the starter plungers which are attached to the starter leaver rods (1 per 2 carbs) and activated by pushing down on the lever by carb #2 (which is marked "Choke" but is not a choke).  More importantly note that 3 of these are the same but the one for carb #2 is different.
startershaftbushings.jpg (23663 bytes) Startershaftbushings - these can be found rolling around on your work table after removing the starter leaver rods.  If your lucky enough to find one in place then you'll know that they go in the lowest round hole on the right of each carb (vacuum chamber on a flat surface, carb bottom towards you), which can be seen in carbapart.jpg on the upper right and lower left carbs.  The other 2 carbs show the opposite side of the same hole that does not have a bushing.
throttlereturnbracket.jpg (30433 bytes) Throttlereturnbracket -  the cable goes through this bracket to the inside of the connecting pulley.
 

Other Notes On Disassembly

Throttle pull cable (with adjusting nut) - cable goes through it's bracket on carb #2 to the outside of the connecting pulley.  See carbsup & down pic's.

Throttle pull bracket - this attaches to the carb #2 coasting enrichment cover, per carbsup1.jpg

Top brackets - these come off before / go on after the bottom brackets.  The idle adjust goes on carbs #1 & #2.

When soaking the carb bodies in solvent for cleaning, the carb numbers as seen in the carbsup pics were washed off!  So, the pictures already have proved their worth to me.  I hope they help someone else.
