For what it’s worth, here’s my old Mosquito weight mod, pulled together by combining a few posts from some other forums…

Continuing our series of modding inexpensive Duncan yo-yos, today’s topic will be the diminutive, yet nicely shaped, lime green Mosquito, as pictured below. The Mosquito is a small butterfly shape with a wide gap, ideal for the younger set with little hands. Unfortunately, it possesses the typical shortcomings of most low-priced Duncans, light weight and friction stickers. While others have recessed Mosquitos for silicone, as I have here, super gluing BBs into a yo-yo for weight is irreversible, not pretty, and may result in the end caps permanently attached! Proposed here is a simple system, quick to make and install, and fully reversible…

Our next victim:

Here’s the inside of one of the halves. Note that the screw holes to attach the end caps are located right near the outer edge, precluding the addition of a solid washer or ring for weight.

The solution is simple and elegant. Simply go to your nearest hardware/home store (such as Home Depot, Lowe’s, etc) and purchase a length of 5/16" diameter (3/16" ID) vinyl tubing, as shown here. I get 20 feet of this for about $4 at Home Depot.

Next, cut four pieces of tubing, each to a length of 1 3/4".

Curve/bend the tubing to sit on the outside edge of the inside of the yo-yo, the ends should press against the raised screw hole recess to hold them in place, like this:

Screw the end caps back on and away you go! I haven’t weighed the yo-yo yet, but it feels like it now weighs on the order of 60-some grams, much better than the original, lightweight value of about 47 grams.

I’ve also added a fairly wide recess for silicone on one of the halves, it’s about 3 mm wide and a little more than 1mm deep. This is just a first attempt for a recess, I may do something on the other side once I remove the friction sticker. Here’s a picture of the recess.

Once the bearing was cleaned and lubed the Mosquito plays very nicely, now that it has a nice weighty feel to it. One thing I have noticed about the Duncan bearings is that they are kind of hit-or-miss. Sometimes you clean a brand new one and it spins silky smooth, others run with a little vibration, don’t sleep as long, and ultimately get binned for the looping yo-yos.

Hot off the scales: The original Mosquito weighed in at 47 grams. The Mod version comes in at 57 grams. The scale is accurate to +/- 1 gram.

The mod version is still a little light…hmm, we’ll have to come up with a simple weight addition program…BBs?

For the BB weight lovers here, 50 Crosman Copperhead BBs weigh in at about 17 grams, so 32 BBs weigh about 10.9 grams.

…As I sit here I’m adding the next mod. The variable weight system! Why did I pick this size of vinyl tubing, you ask? Simple…it fit in the yo-yo, and, guess what fits snugly inside the tube, especially when the tube is bent around the edge of the yo-yo? You got it…BBs! So, I’m adding 32 BBs right now, eight in each tube, which should add about 10-11 grams of weight. I’ll see if they stay in place once I get done and throw it a little…Sorry, I’ve taken no pics of the BBs in the tubes, use your imagination!

Final weight: 67-68 grams. None of the BBs appear to be moving after a good number of throws…Success!

I hope you’ve enjoyed this edition of Duncan Mods. Come back next time and we’ll take on the Dragonfly with the same weight technique, only this time we’ll make a complete tubing circle with the same, cheap tubing!!!

Enjoy!
