I'm sure some of you talented machinists, welders, and tinkerers have created some cool stuff for your bikes. Let's see what you have made.

I didn't exactly "make" it, but I did have a friend weld up a connector pipe to a real carbon fiber silencer. Here's the story:

A friend of a friend worked as a factory mechanic for Team Suzuki. When Damon Huffman moved to 250s (and Kawasaki,) there were some semi-works parts that got shuffled in the mix. Nothing internal or too exotic, but there were lots of footpegs, custom brackets, etc. from the old factory 125s. My friend gave me one of the silencers that had, presumably, been on Damon's works bike or one of the test bikes. It didn't fit my YZ125, so I cut off the silencer at some point along the front, aligned and cut the YZ125 silencer in the same spot, and had the two joined together.

That was a trick silencer! The metal looked like mild steel, but the carbon was pure, weaved fibers. No epoxy at all. You could actually squeeze it and feel the shape deform quite readily. Who knows if it made my bike quicker (probably not,) but it was trick!

At first glance I saw a chisel, and thought to myself "Hmm that's odd to bring into the bush"

Then I looked closer Laughing

Very nice. I hear the newer model has a slot for the lighter too.

I made a power valve spacer for my 2001 CR 250. 

I used to cut about 2” off of my stock 4 stroke silencers and re rivet the end caps on. 

Made the power valve spacer on my current CR125 but most proud of my current tank mount washer. Lol

In middle school, I made a bike stand with a lever, and a down pipe for my '76 YZ80C.
I got the dimensions for the pipe by measuring each segment of the pipe in a magazine ad, then scaling it up to real world and doing all of the calculations.
I used a Volkswagen bug stinger for the silencer, which is something local racers were also doing.
The pipe fit, but probably did not improve performance. In the end, it was a very cool experience.

I haven’t don’t anything crazy, I don’t have the skills or machines to do the badass stuff. I did modify a triple clamp to fit newer ktm fenders, but that’s about it

Cut, machined, welded and finished the bottom fork lug on my '03 YZ250 to accept a four piston radial mount Magura caliper. Made some groovy wheel spacers for the same bike that have a bigger outer flange to offer the seal a little more protection. Machined and welded on a steel flywheel weight, also for the same bike. Came out perfect and needed no balancing.

Nothing I made, but Kenny (TyDog) cut a 78-80 Cr250 rear engine mount for my Fox Cr. Kenny also cut the head for Joe Newmann's Richter replica, now at one of the Fox museums.

This makes me realize that I have no discernible skills what so ever. Nice work on the caliper!

I'll dig up a picture tonight. In 2006 my dad made a "moto tray" to sit on the seat of your bike for tools and bolts while you work on it. Then another version that clamped on the rear fender if you have your seat off when you are working. Showed John & Alex Martin @ Berm Benders Raceway. They liked it but then John says, "well I want one that can hang near the shock mount when the subframe is off." Then we didn't make any more. haha. Had about 30 made. Sold about 20. Only $20 each. Then in 2009 a company "Tool Seat MX" made the exact same product. Kind of felt like they stole the idea. But its not as popular of a necessity as you'd think. That company went out of business too from what I can find.

In 1990 I was working as a welder for Kitfox airplanes. I made a bike stand out of .035" chromoly tubing in .375 diameter.

I basically modeled it off a normal stand but the sides I rolled just enough to fit a VP gas can so you could flip it over and throw your gas can in it. all said and done it weighed approx. 14 ounces if I remember correctly.

It lived until I quit racing in the late 90's. I could have sold 1000's of those things , it was so cool.

Machined a spacer to fit 4 stroke brake pedal on YZ 2 stroke
Wired vortex ignition select switch to KTM bar mount switch (hate that giant yellow switch)

3D printed flush mount gas cap for YZ R-tech tank, relocated vent and used P clamp to hold vent line to side of frame instead of through steering stem

On my big dirt bike, my BMW gs800 I made a rear rack to attach camping gear bags, but had an inside section that would fold up vertical to use as a back rest for my wife on some street rides. I made a pad that slid over the back rest section. It came out much better than expected! Can't find any pictures.

What material did you use for the gas cap? It doesn't leak?

Built a Custom Header for my 2019 FE450. Scaled the lengths on Bluebeam and then cut and fitted the header. Dean Dickenson provided the Vortex ECU with several different maps to get the fueling correct as the longer header created a lean charge. Made a completly different bike

Probably the coolest thing I’ve done to date (at least that I can post about without getting fired from my day job) is the YZ-EMX project that I just finished and raced at the Reno EX round. I’ll post a new thread with more photos and videos eventually.




I’ve also been designing swingarm extensions for hillclimb bikes for a couple years now, I don’t machine them myself though I just do the CAD work. It’s a little more complex than you’d intuitively think at first glance, mainly because the brake and chain guide need to line up perfectly and also be adjustable for each axle position.




And as a lot of you know I also do all sorts of 3D printed parts through my side business 3DP Moto, like intake scoops, cable guides, swingarm plugs, etc.





I can’t get away from this crap and there’s even more on the horizon Laughing

I didn’t do the print I did the design. The printer that was used was a laser sinter type and the material is chemical resistant, I’ve tried it in a bucket of gas and it didn’t eat it away. Haven’t had it on the bike but shouldnt leak, fits as tight as stock and has an o-ring groove at the top to catch anything in or out.

It works better on bars without the crossbar.
