How to clean REALLY nasty jets?

[oscarmayer]

you can soak them in chem dip carb cleaner. it's a 1gallon paint can size cleaner found at nearly every auto parts store in america. drop them in let it soak over night, wash with soak and warm water and clean!

I have heard that boiling metal carb parts in white vinegar cleans them to new condition.

I have also heard that you want to do it outside, on the side burner of the BBQ with an old saucepan, that you can dedicate to the cause. This keeps it all quiet on the homefront.

I useold throttle or brake cable wire.Took only one small wire,they are smaller than torch tip cleaner.Sometine I use a hand operated hydraulic power unit,I install a hydraulic pull on the hose,drill a hole and tap the good thread,screw the jet on it and apply pressure,any varnish doesn't resist to 2000 psi oil pressure....

Jets are really cheap man. Just get new ones.

TORKER.

I agree, you will be much better off. However I found out today that the needle is NOT the same. The replacement kit I got, caused my bike to bog out when snapping the throttle. I had to re-use the old needle, not a problem at all, just saying

Johnson/evinrude engine tuner works great. Let them soak for a hour or so and the jets will look almost new again.

I wouldn't use torch tip cleaners, they are abrasive and could enlarge your holes, which i guess could be okay as-long as you are careful. Those jets must be available check out your local Harley dealer. Around here they have the biggest selection of jets around. If I going to try and scrub the inside of the jet with anything it would be just a small piece of copper wire strand.

K&L supply sells a jet cleaner kit. Looks just like the torch or welding tip cleaners but with smaller wire. They work great www.klsupply.com page 78 if you download the catologe pdf. All the mechanics at a few dealerships I worked for used them all the time.

dude, if I can not clean the jets by soaking them over night and simply using the bristle from a wire brush, then it is time to replace. Now, if I was stuck in the middle of nowhere with no access to parts, only using what I have in my shop? I would use a needle from the ol lady's sewing kit or even make a shard from something hard. McGuiver would get down with a toothpick and some bubble gum, but I am not that innovative, hahahahahahahahaha

Just clowning bro, You have any pictures of these dastardly jets?

Wow thank you all very much for all of the great advice that was given!

I got the jets cleaned. I just took a very small peice of wire and pushed it through very slowly and very carefully.

I did not try to scrub the inside of the jet or anything; I only made a hole through the junk that was stuck in there.

Once I opened the hole back up, I just blasted WD40 through it to get any other junk that was in there, out.

Jet appears to be fine now. Hole is perfectly circular, and when I compare to to my smaller size jet, the hole looks bigger than the hole in the smaller size jet (and they are both the same exact jet), so it must be all cleaned out now.

I also soaked it over night in carb cleaner after as well.

Thanks again guys.

If you're talking about those corroted ones (mostly the pilot jets) that you just cant seem to get something through you're probably past the time of cleaning them. The corrosion eats away the brass and interferes with the jet size.


Dont buy the jets specfic for that machine. goto your local motorcycle shop with the brand of your carb (I think mikuni) and tell them you need this size jet for a mikuni carb. The number is on the side of the jet. Voila, you got new jets! If you cant find jets still, pm me and you can paypal me the money and i will pick them up and ship them back to you....I know for a fact i can get them all day long.

Also what racerguy said. Jet cleaners are awesome, but you still have to be careful and not force something through. They are made of steel.

[unclejemima]

the urge will be to shove something through the holes,try not to.if you have to try something plastic or brass.

I like to use toothpicks (the ones with the pointy end)
Dip the toothpick in carb cleaner, and gently insert the tip in the jet/hole while turning it left/right to remove gunk. Works great. Its soft so it won't scratch or damage the jet, and it is slightly abrasive to is will clean it as well.

i boil all my carbs and carb parts in plan h2o then clean then out with air and carb cleaner.
