    Pilot screw adjustment tool?

    Anyone made or found a tool that makes quick work of pilot screw adjustments? I don’t mind loosening the clamps and tilting the carb, but entry from the right side of the bike seems like if there’s the right stubby screwdriver or ratchet attachment it might be easier?

    Please post pictures of your methods, tools, or creations!

    Stubby blade screwdriver can work but I now like just a 1/4' drive hex blade bit about 1.5 inch long.

    I bought one of these plus an extra air screw in case I messed up, and modified so the new screw replaced the one that came with this.

    I have a bunch of photos on how I did it, and if I find them, I'll attach here. But basically I just chucked up a drill bit in my press, clamped the air screw between a couple blocks of wood so I wouldn't damage it, then bore drilled away. I attached using Liquid Steel. This works great for me as I ride areas where the elevation can change by thousands of feet in a day. I've even been able to adjust based on air temperature; warmer air being less dense than cold air, damp air also less dense than dry air. When I go to the coast, I can adjust for that as well. Just a twist of knob as I ride to find the sweet spot and I'm rippin'!!

    I've tried several different things on mine, they all worked, some easier & more/less accurate than others.

    If I was buying one for myself, or you, (I'm not!) I'd jump on this eBay Chinese special:

    $3.21 and free ship. That's one of those "Sore Willy" deals...you can't beat it!
    Estimated between Tue. Jun. 4 and Thu. Jun. 13.

    I've used one like this...Easy Peasy!
    And you don't have to rotate the carby.
    It shows it being used with a power drill.
    Just use fingers, of course!

    This I would like to see....looks like a great idea and doesn't cost much. I ride year round and seasonal/weather based adjustment seems like a great idea. Weather patterns and air pressure changes wouldn't matter anymore!

    I just ordered this on amazon trying to avoid going mad scientist on perfectly good tools... we’ll see how this one works. Might be a good one for the books with all the people making regular temp/elevation adjustments!

    Once I saw you could just use the ratcheting disc by itself, it looks super low-profile and might be the perfect size to just place in your hand and line up coming in from the right side of the bike over the exhaust pipe.

    That's a good idea! They didn't when I did mine around September of 2015. Or if they did, I didn't realize it.
