Sometimes, the DIY universe works in mysterious ways. It was just last week that I shared Superfastmatt's latest video, where he took us through all the experiments he's been running in 3D printing metal parts for some of his automotive projects.
And while the mind-blowing exhaust header setup he shows off was made to his specifications, specifically for his land-speed-record car, it's not at all difficult to see how these processes could benefit any DIYer who wants to take them up, including motorcycle and powersports enthusiasts.
Just a few days later, the wonderful Driving 4 Answers channel posted this exploration of the trial and error process of 3D printing a new intake boot for a vintage Yamaha TTR 600. After trying repeatedly and eventually admitting defeat with getting the original two-stage carburetor tuned the way he wanted, D4A ended up fitting a totally different Yamaha carburetor (off a Raptor 660, actually) to the bike instead. And it worked, but clearly the old boot was no longer the correct dimensions for the job, so then it created a whole new problem he had to solve.
