I’ve got a huge beef with electric scooters in Canada. First off though, I do want to discredit the myth that I dislike them. The opposite of this is true; I prefer electric scooters. Far over gasoline, I would rather have an electric scooter.
Continuing the scooter rescue, I had picked up this 1984 Honda Spree for free from Nanaimo. It was in severely rough shape, having not followed the recommened “Not for offroad use” sticker posted below the gauge cluster. Another sticker posted on these scooters is the tune of “Don’t modify, you’ll just make it slower.” And it’s the truth, for those of you just getting into scooters or other 2 stroke engines, there is a difference in your approach to modifying a 2 stroke versus a 4 stroke. Yes, it’s true, the more an engine breathes, the better the performance, however 4 stroke engines have valves controlling the timing and volume of air entering and exiting the cylinder. That’s a nifty piece of engineering as 2 strokes generally do not have this luxury. Instead, 2 strokes have open holes in the sides of the cylinder, and depending on the position of the piston in the height of it’s stroke, will determine whether air is entering or exiting the cylinder. At one point in the stroke, both intake an exhaust ports are open! What this means is, depending on the pressures on either side of the cylinder, intake and exhaust pressures, air will naturally move to the side with lower pressure. What does this all mean? It means, unlike your 4 stroke car, you can’t just open the exhaust and intake volumes, with mufflers and intake systems, freely without consideration. Both must compliment each other, so that when the piston drops down to exhale and inhale, it’s not just going back and forth through the same/wrong port!
I probably missed a few descriptors, but I whatever.
6 years ago I came up with a wheel design that I had really wanted to see. At the time I did not have the skills to really create an appealing visual to represent my idea. I toiled in my regular 3D programs but couldn’t quite find the right information, create the right shapes and overall present the right idea. The idea was another stuck in my brain, without translation to a good medium for others to see. At the time, I had shared some rough drawings with a designer, he whipped up Solidworks and cranked out some wheels. They looked great, but, his interpretation of my vision was quite liberal aside the original idea. You can see his interpretation here.
I saw promise in these and entertained the idea of manufacturing them. This avenue narrowed, and the road ended fairly quick. Skipping a few years in the future, a girlfriend I was dating at the time was going to a local community college. This community college featured course in CAD. Unable to afford to attend, using her entry I was able to sneak into the computer lab late at nights. While she did homework I spent the next few weeks teaching myself solidworks.
Skipping another few years ahead to the present, I was finally in a financial position to afford a computer quick enough to run solidworks. After a few test pieces recently, I decided to just in head first and build the Centauri wheels the way I had imagined them nearly 6 years ago. So, I present to you, the two piece, adjustable offset, 15×9, dual Bolt Pattern, Speed Hero DP1S Centauri Wheel. Thanks for reading!
