Stuck Pilot Jet removal

Ok.. Well I've had my Carbs off 3 or 4 times now, cleaning things and getting the big running smoothly and learning along the way.

Only last time I took the jets out, one of the pilot jets was stuck. Now I have seen written here that the ONLY way to get brass bits out is to use a close fitting screwdriver, I didn't have one the right size, so I took a belt sander to an oversize one and got it asclose as I could.

However, when I tried to remove it, the brass started to sheer. Not being a dumb ass, I decided to stop and ask here before the jet was bady damaged.

So here I am.

How do I get a stuck pilot jet out? I'm intending to replace them all, and as it is, I don't need to do anything to this particular jet until I change them all, the bike runs, but I want to know how to get it out so I can when the time comes.

 

Some penatrating oil , and let it set overnight. Try again the next day. If that does not help then add a little heat with a propane torch. Heat the body of the carb around the pilot jet, put the screw driver in and give a quick turn.

 

Now, you have to fabricate a screwdriver that has ZERO play.
None.

I use a few different tactics depending on how it looks.

Sometimes I put a few drops of OLIVE OIL into the Pilot Screw Hole and put the Heat to it.
The Olive Oil will super-heat without flaming-up and boil away impurities plus seep to allow things to start moving.

For stubborn cases ... I have fabricated tools.
A cut-down and Dremel-grinded SnapOn Screwdriver with a set of Hex Flats just below the Handle.
I use a Box Wrench held-onto those Flats and a 3-S DrumStick to apply Impact on the Box Wrench with Undo-torque started, ... awaiting the sudden application of moderate impact.

Same deal.
Soldering Flux.
Heat until it runs and then heat below the Mix Screw.

 

Rick,

Are you referring to the Pilot Jet or the Pilot Screw... Isnt swissjon talking about the jet & you are referring to the screw....

Sorry if I misunderstood....

 

Well, ...

I thought we were talking Mixture Screw.

But, if its just a Hitachi Pilot Jet, ...
If the threads can handle it ... Heat and Muscle.

Worst case, ...
Vice Grips and explosives.

 

Yes, I agree..I have a Pilot jet that is really nasty....might to resort to vice grips & a flame thrower....LOL

 

I use Locking Needle Nosed.
You KNOW it's coming-out.

What condition its in AFTER it does come-out ...
That's the 64-Thousand dollar question.

Just remember the 1st Commandment of Stuck Jets.
DON'T ... BREAK ... A ... FLOAT ... PILLAR ... !!!

 

Speaking of float pillars... the ones that Chacal provides does not have the filter screen, but does it matter any? How much filtering does the screen provide?

 

I was talking about the jet, not the screw.. But the bike's running at the moment because I stopped before I damaged thejet hole..

I've some pods and a jet set on the way, at which point, I'll get the damned thing out.. Vice grips and heat I think.. LoL.. Then my pos/jets will give me a nice new problem to tackle.. But that's an entirely different thread!

Judging by the amount of crud I cleaned out from my float pillers, I'd say the filter is essential. Mind you, I'm pretty sure that's the first time the carbs have been apart in 25 years, so that was 25 years worth of crud...

 

Having a Inline Filter will keep-out what gets by the Petcock Screen.

Assuming the Petcock Screen hasn't fallen-out.
