    Low speed jet plugged

    I took apart my carb this past weekend on my 2006 tw200 and found that my low speed jet was partially plugged. I cleaned it and i was amazed how much more power and response I have. I did the same to my sons 2010 Honda crf80 and his was plugged and it brought his bike back to life. I notice that both low speed jets had like a web or screen halfway down the jet before it sprays through the tube of the jet. Has anyone drill out this screen or web to prevent future plugging?

    I dunno.. having that web there prevents any particles from getting through, but does present the issue of maintenance to insure that it stays clean and clear. I would think routine checking of the strainers is needed until you discover the source of the contaminants (rusty/dirty fuel tank and bad fuel filter?).

    Are you sure?

    I have not seen a screen in the slow speed jet (pilot jet) in a Teikei carb.

    I would post a picture but Photobucket is holding all my carb photos for ransom.

    ...figured out how to attach photo....

    The "web" is crap from the ethanol laden fuel we have nowadays, it's not supposed to be there....

    What rbm says. I have found the blockage as soon as 2 months. It does look like a tiny web inside the jet.

    A little Lucus Deep System Fuel Cleaner or Seafoam once in awhile solves this problem.

    Hey guys, I'm having trouble getting my 2005 to crank and idle without the choke. Does okay at half choke. Immediately dies when I press the choke in. I have soaked the main jet , pilot jet, as well as the whole carb twice in chemdip, followed by warm water and compressed air. I can't get the smallest wire of my torch-tip kit to go through the pilot jet. I can barely see a hole at all. I suspect this is not normal. Can any one confirm? Has something fossilized in there? Should I take the smallest drill bit I can find and try to ream it out?
    Any input appreciated.

    Welcome to the forum!!

    Typical signs of a clogged up pilot jet. Save yourself a lot of hassle and buy a new OEM one. If you can get some Lucus Deep System Fuel Cleaner it might help.

    No screen in the slow speed jet. Here are a #36 and #45 from both ends. No screen.

    On a semi related note, has anyone bought this from Procycle- and if so what sizes come with it? Alternately do you guys know any good places to but Teikei jets at?
