Dimple goes down, don't strip the screws, got it. Thnx everyone. Now I'm starting to get excited.
Hey Apache Snow, i went down to my local bike shop today and got a few different main jets and had to order the smaller pilot. I'm really interested to see how my bike will run with your settings because we're close in year and elevation so i may leave the pilot in and swap the main... though that does totally seem weird. I don't see how leaving the 55bh in and swapping the main is going to let me back out on the mixture screw. whatever let's give it a try.
 oh and one more question,,, what is all of that nonsense underneath my tank? there's all kind of weird connectors and black circular looking electrical dodads underneath there. what can I rip out and what could I relocate do you think? I have a schematic but its kind of a crappy one.

Now that some of the dust has settled, I am curious how your vacuum line is plugged, I see the hex head in there but are you sure no air is getting by the threads? Did you use a sealant to seal the bolt threads airtight?

Definitely, will PM, but I am not the mechanic expert, just got my bike in March.

yeah I'm also interested to know what the difference would be. and I think I might have installed mine dimple up also. actually what I'm trippin on is when I install that plate with the needle and spacers and all that, I actuate the needle up and down (i guess just to get acquainted with its movement) and noticed last time the needle head or clip or washers or whatever wud kinda get stuck. but I'm thinking that when its installed it doesn't move back and forth to have the chance to get stuck.

 yeah well there we go I guess I just answered my own question haha

oh wow! i wish i had seen these pics two months ago. you know what I now remember that when I installed that plate, the little notches in it lined up with the two other screw holes. thats probably leaning out my mixture a bit. darn,, looks like I'm working on my carburetor today haha

A CV carb (constant velocity) uses vacuum to raise the slide in the carb. Nothing to do with the petcock

here's a pic of the plate properly seated. i dont know why my phone decided to crop half of it off. i dont know what the dimple would be for other than a marker used to tell u which side fits proper. I have installed it with the dimple up and wouldn't have know it was wrong by feel of the bike. I had my doubts because when you install it dimple up nothing really lines up very good.

Anyway i reinstalled the orginal pilot (probably stock, the tops kind of messed up so I can't see any numbers), and dropped in a 152.5 main jst for fun... holy sh*t! way more power and a much much smoother power curve. only one little pop here and there when upshifting, nice smooth rumble on the way down. still get a backfire on shutdown.

oh the numbers are on the side? i'll check it out next time, that carburetors not coming off again today. actually I should clean out my shop and get some paintings done, im broke. oh thats another thing,,, I built a spray booth in my shop just big enough for a motorcycle. im pretty good with clear coat 'cause I use it to seal my paintings, but it would be nice to start shooting some solids and working on some bikes.
