There are 2 rubber like plugs at the bottom of the block jet assembly (37 & 41) in the diagram they are called Caps.

I will stop by the Yamaha shop.. my local shop will have to order & no doubt they will be 4 times the price you paid (at least).. I have been looking on the net but have yet to find the parts. Partzilla does not show the parts... (unless I'm blind)... Next question.. have you ever have one stuck? other 3 came out... 4th loosens.. but I can't shake it out..

I have a couple more questions.. The fuel passage caps? How often/condition do they need to be replaced? The o-rings on the diaphragm cover? Replace if they are hard as a rock? Are they a standard metric or specialized metric size?

Howdy All, I decided to take the carbs off (again)... pull out each jets, clean everything, and discovered 1 fuel mixture screw that won't come out (it appears this is another thing (s) the PO screwed up). I also did not see any o-rings on any of them (required?). Is there a source for these little buggers?

Mine is a curvy, uneven, 20 + degree (elevation)... With the new progressive springs without the pvc spacer & 7 psi in front, auto low in back w/ damper set at 1... perfect..

Ok VR enthusiasts... I pulled that fork apart, smoothed the divets (made by PO) as much as possible.. put her back together.. will ride this afternoon.

Thank you for all the responses. I synced the carbs yesterday - Success! What a difference. If I get time today the fork (yes, only 1 side has an issue) will get fixed (3rd time is a charm, right?).... I also plan to remove the spacer that came with the new Progressive springs, this should lower the front end 1" and help control-ability on gravel... Yes, I live on a gravel road up a mountain... Control is crucial....

Thank you for your insight. I just spent awhile setting up the Carbtune, then "Think" I got the carbs synced. All four are really close, not perfect. Does this mean I may have to adjust the pilot jets? The PO really messed up this ride, I bought it in early July and have been tweeking everything. Rebuilt the brakes, had the forks torn apart twice, put in new Progressive springs, the right fork seal was leaking when I bought it, 2 seals later, it still leaks (I think it is being caused by small divets in that fork just above the seal. The left fork they used a fork seal washer on bottom, which caused that washer to slide down the bushing, subsequently causing the left fork to bottom out.

The Morgan site references that tool. This just seemed odd. I did not see any reference in http://www.venturerider.org/forum/showthread.php?495-Syncronizing-Carbs. I am going to print off the procedure and head to the garage.. first is my Venture... then my 80, 850 Special.

I was having issues with my 83 running really hot. After I totally drained the coolant, I refilled with Amsoil coolant, since then even 100F days have not been an issue. Warning light always flashing, gas (on/off)/battery (on/off)/ headlight (comes & goes) low brake fluid, low engine oil comes & goes.

Howdy Venture techies, I have a 1983 Venture, after several times of removing/reinstalling the carb bank I feel it is time to synchronize the carbs. I picked up a Carbtune Pro II 4 gauge. Something puzzling me is something called a YICS SHUT OFF TOOL 90890-04068. Is this a requirement? If so, it appears I might need some advice... Thank you in advance.
