carb adjustment question

First of all, merry Christmas, y'all.

Just got a replacement set of carbs and I've decided that so long as I'm pulling the bike apart to put them on, I might as well get the old girl breathing better. I'm looking at a set of v&h cruzers and an ear shave. I've read about how to reject for each procedure individually, but since I'm doing both at once, I was wondering if anyone knew what size jets to go for.

Ear shave is so common and the cruzers so popular, I figure some of you guys have done both. What do you guys suggest?

no need to re-jet for the pipes just go with the re-jet recommendation specs for the ear shave and you will be happy

i havent done the shave yet but i am running stock jets with the air fuel screws at 2 1/2 turns with the cruzers and the only thing that has changed about the bike is the better sound

It was highly recommended to rejet with 142/42's and 2 shims under needles when I did ear shave. I followed their advice and have been very pleased with results.

The saga continues...

Upon further inspection, my throttle cable hangers were JB welded on. Quick call to the shop and the resident "expert" tells me I ought to sell the bike. Says that I'll need new carbs, which cost around $800.

To ebay I go, picked up carbs in good shape for $125.

Ordered shims, jets, filters, coasters.

Might as well put the new exhaust on while I wait for the UPS man, right?

45 minutes later, I bust an exhaust manifold stud tightening the last acorn nut.

Swear loudly, kick something, repeat with the voice of my father echoing in my head, "torque wrench....TOOOORRQUUUE WREEENCH!".

I've been showering the the thing in PB Blaster all week. There's enough of a stud left for me to get some channel locks on it. Maybe this weekend I'll be able to get some miles in, provided I don't break something else.

EDIT: My old hippie neighbor came over and mumbled something about needing to synch the new carbs before he began pawing through my record collection. Am I going to have to go buy manometer and all that jazz?

Pipes are on, loud as hell.

Put in new jets, go to adjust fuel/air mix screws...

Plug? What is this plug?

A quick forum search later...

Am I going to have to take a drill to these things? Is there a way of getting to the screws that is less potentially destructive?

Some suggestions I have read are to drill a small hole and try to pry them out or put a drywall screw in there and then pull the screw and plug out together. I guess I was lucky and mine were already out.

X2 I drilled a small hole and then plucked the cap out with a sharp awl.

I'd think you could punch a hole in the plug with something like a thin finishing nail, cock it sideways and pop it out. That's how I got them out of auto carbs and throttle bodies.

Don't want to hit the screw that's behind it.

The plug is the same setup as a freeze plug on a car engine, if you've ever had to deal with one of those. I get the freeze plugs turned sideways a little, then bite with vise-grips and lever them out with the vise-grips against the block.

The air screw plug is a lot smaller and the aluminum body a lot weaker on the VN carb. Maybe turn it sideways and use needle-nose pliers to pull it. Mash it to make it small enough to come out if you need to. They're fairly thin and weak. It can't fall inside.
