Stuck Jets

[Nessism]

First thing: ungang the carbs. You can't use heat (nor rebuild) the carbs all assembled like they are. Since the gang plate screw(s) are stripped you are going to have to turn them out with a pair of vice grips or cut a slot.

Secondly, drill deeper using a smaller bit and work the bit sideways to be sure you are centered. If you are not centered you will ruin the carb body. The idea is to start with a small bit and step up in size until the shell of the jet spins out.

Yeah, I've been debating that. Should I take it to a professional? A local shop, Brenny's Motorcycle Clinic, charges $100 per carb, for $400 total.
I like learning how to do things, and I want to be able to work on my bike myself. However, I'm still out of my depth on many things, but I don't know many people who will work on them.

Who is Steve?

Steve is the man with the experience and facilities to fix your carbs.
There are others too.
That's preferable to bashing your head off a wall trying to fix something that's becoming a total pain. There are times when it's just more worthwhile to hand the job over to someone who can do it right, and for not much financial pain.

Well, that's certainly no way to get his help

He's posted thrice in this thread. You need his help.

Here is the jet I tried drilling.

That's the problem with the internet: so much conflicting advice. A heat gun, a propane torch. A propane torch will ruin it, but a heat gun isn't enough.

Who is Steve? Also, pictures incoming.

Gotta give it to ya ZPS. I like trying to do just about everything myself, too. But I think I'd have given up on these carbs by now and begged Steve to overhaul them for me. I'm sure he'd treat you well. Just my $.02.

A heat gun isn't enough. You need at least a propane torch, if not oxy-acetylene.

Don't give him any ideas!
hey zombiepotatosalad, are you now working on the jet tube? Or still the stuck pilot jets? If the latter, how about a updated pic so we can view crime scene?

Yes. I got a heat gun. How long should I heat the jet tube?

[tom203]

The idea here is to hollow out the jet slowly and get the bit to bite into the remnant.
i trust that your bit is going counterclockwise??

[Steve]

Turn the bit SLOWLY. Let it dig in, rather than spin out all the chips.

.

Using the left-handed drill bit seems to just core out the jet, but it doesn't seem to loosen. Is that supposed to happen? This process seems more destructive.

[Steve]

I’ll have to remember the Torx bit idea, but I have always used a left-hand drill to extract them.

Get genuine mikuni...according to this carb spec chart, you want #40 pilot
