rebuilding carbs off a 1980 with carb #vb62 and these are the ones with friction fit low circut jets #35 with 110 mains,just the 80 like this?
owner got me napco kit part# 48-1993(stock#11-h1008)honda cbx1000 79-80,these have the 65 and 98 main jets and plugs for the low circut.
are these the right kits or the for the 81/82s?box says 79 -80,do they have kits with friction fit 35s and 110s?if they do i cant find em?he got these from parts and more and the have no phone # to call just email,makes me leary
he ordered new air tees from randakk yesterday. great site.love the distilled water to kleen trick works great
i found the thread on pulling out fiction jets,great read/should of listened on the bolt part,first one came right out but i used the tapp to pull it and when i went to unscrew the tapp from jet and it broke off in jet :oops: after grinding down around the tapp i was able to grab with plyers and unscrew,after grinding down i have 1/2 the hat area with no damage to the 35 hole.think we are gonna replace these sirius will have some in 3/4 weeks.

Looks like you have the pressed-in jets figured out. No 'kit' comes with replacement 110 mains - the '80 VB62 carbs were the only ones with that size. And DO NOT use the rubber plugs. A much better option would be to buy Randakk's complete rebuild kit which includes everything rubber-wise that you need and is of excellent quality. Good value too. Good luck!

The vb62a is a completely different beast than the 60a. The 60 uses transitional main jets, one of which shares air with the slow circuit, and a rubber passage plug that goes between them. The 62 has a single main, hence no need for the passage plug. You can find jets on ebay--just don't buy cheap chinese ones. Even with new Keihin branded it's never a bad idea to size them with a probe of the correct diameter.

Just make sure that you break them down all the way--some folks are tempted to skip a step but it almost always turns out to have been a poor call. For example, if you stop short of pulling the choke rods completely out you'll almost certainly have a nightmare of a time. I've had to rehab more than one set where a previous technician decided to leave the rods inside the #3 and 4 bodies and then bent them during assembly. You'll know when you see that they're binding hopelessly.

I second the note about the randakk kit. I've installed a couple of his master kits lately and the quality is up to snuff with the parts I source independently. His site is a tremendous resource if for no other reason than because the guy's such an articulate writer. You should buy something just to compensate for the time he's spent.

Have fun!
