One thing I don't like with the replacement t-hoses (any brand) is that they no longer fill up the hole in the frame so it looks a bit odd. We just happen to have an SLA 3D printer, so we whipped up some custom rubber grommets to clean it up a bit.

The printer basically solidifies a part layer by layer from a vat of goo. These printed out in about 6 hours, then they go into an alcohol bath to remove the excess goo, then into a UV chamber for curing, then the supports are cut off, and finally sanded smooth to create the finished part. Not as nice as a molded silicone part, but they will do the job and we didn't have to spend thousands of dollars on tooling to make it happen!








Great job!

Close up Pictures make them look huge but what are they about 1.5 long by 3/8? How many hours did it take the printer to make them?

Thanks! They only overhang the hole in the frame by about 3.5mm, so they're only as big as they need to be! Overall size is about 1.5" x 2". 6 hours to print, but there's the cleaning, cure, and finishing time to consider as well. Probably 7-8 hours total, but only ~30 minutes of that is actually spent doing any work, it's mostly all automated.

Laughing my ass off at how Billy just subtly flexes on all of Vital and our "builds" where we just bolt on parts. I'd expect nothing less of you just "whipping up" you own rubber grommets haha

I have some wheels that you should see tomorrow. Any chance you'd have time to whip up some clamps for our '02 CR?

Cool

Looking forward to the wheels! And clamps are in the works, but it might take a few months!

Make a silicon mold of them so you can reproduce them cheap.... then offer them to customers. You're not the only one with this issue!

Some goodies showed up from Faster USA yesterday!







Faster USA hubs laced to Excel A60s. This is one area where we're sacrificing a weight increase in favor of performance and longevity. Stock wheels are really light, but these are a lot stronger and stiffer. They've also got an extra bearing on the rear drive-side to beef things up some. We've run Faster USA wheelsets on our last 4 shop bikes and have never had a problem; we've never even had to touch them with a spoke wrench, everything has stayed tight as new!

For this build we went with the Tubliss system. We've never tried these, but they have good reviews. Installation was a bit different than what we're used to, but not all that difficult. The front is actually heavier than stock, but the rear is lighter, which we found to be a bit strange. We might replace the front with a standard tube for that reason, plus I've can't recall the last time I had a front flat but plenty of times pinching the rear.





Once the tires were mounted we threw on a set of Motostuff rotors and Renthal sprocket (49T) with titanium bolts for both. Rotors are a bit lighter than stock on the rear and about the same weight up front, but that's also oversized at 280mm. Holding these wheels to the rest the bike are titanium axles with axle blocks made in house.

Very nice work as usual.
Since you have been talking weight savings did you get a chance to weigh any of the different tire options before selecting those? I lost over 2 lbs going from Dunlop’s to Pirelli!



I can’t find the rear pics but here is the front. 1.25 lbs just for the front alone. IIRC the rear was the about the same if not more.

Amazing work! It's especially cool seeing one-off stuff like the 3D-printed hose grommets that you can't just buy and bolt on. The creativity is what sets this thing apart...

StarCross 5 are lighter again.

Also talon rear sprockets are lighter than Renthal

Yeah, the Michelins are really light. The new Dunlops are supposed to be a lot lighter than the older ones, but still not quite as light as the Michelin.

Just bought a Hoosier and boy are they light. 4.8kg for a 110-90-19.

I thought the new Dunlop is heavier because of the increased land-sea ration and the addition of tie bars.

OK, some miscellaneous updates:

The rocker arm comes with steel buckets on the shock pivot and I couldn't just leave those stock! So I machined up some titanium replacements. Not a huge weight savings, but it's there and matches all the other Ti hardware nicely:





The Dal Soggio inserts are red, which won't match my color scheme at all, so obviously I have to remove those, strip them, and re-anodize.

One annoying thing about the Dal Soggios is that the compression adjuster is too big in diameter. It covers up the bleed screw at times and it won't allow for a bleeder to be installed either. So we cut them down so a bleeder will fit. These will be stripped and re-anodized as well.

Here's the interference:


The fixture to hold them to the machine:


The freshly cut adjuster:


Plenty of clearance now:

Speaking of linkage knuckle, I emailed Brian a few days ago about sending one to OZ but I haven't had a response. Any thoughts on helpinge buy one?

I know he's super busy at the moment, but I just sent him a message so hopefully you'll get a response soon.

Milled up some high-speed compression adjuster knobs yesterday. No need for tools anymore and makes for a quick adjustment. These will be available in a couple weeks once we get them back from anodize and laser etching.

Milling 5 at once for the first setup:


Forgot a picture of the second setup, but that one drilled and tapped the set-screw holes up top. Here is the third (and final) milling setup after the run was complete:




Here it is on our Husqvarna. We designed this to be as large as possible so it would be possible to turn it by hand. It's a little tough to turn, but still very doable:

Not sure on the KYB size off hand, but these fit a 17mm hex and require a circular clearance of 38 mm (1.5") in diameter (so they can be turned). If that all fits, then these should work fine.

They are 17mm hex as well so you should be good to sell these to that market as well ??

How much for the HS shock compression adjuster? I like that idea... tired of bring a wrench with me out on trail rides

Not totally sure yet, but we'll have it on the website when it's available. Still waiting on anodize and laser etching, it will be a week or two.

Started to get into the engine this week. Splitting the cases for cerakote/anodize and to look things over and figure out what exactly we want to do:



Since these are all off, we knocked off the casting lines and cleaned them up a bit, then blasted them. These will go off for hard anodize (black), which will match the engine mounts we already did.

Like our last 150, we're making new covers for this one too. Luckily, nothing has changed from the last generation model except the clutch cover thinned up a bit for the new clutch. Everything else was the same, so we only made minor changes to our last designs to reduce some weight and make minor adjustments. The clutch cover design thinned up as well for the new clutch.

The raw billet stock starts out like this, there's a lot of material to remove!


For the most part the covers follow the same process. Here's the ignition cover: we machine the first setup in a "standard" vice:


Next the part is flipped over, but it's no longer a nice square surface. So we have to machine a special set of soft-jaws to hold onto it:


For the ignition cover in particular, clamping it in the soft jaws will distort it and you wont get a proper cut as it will relax once you remove it from the vice. So we have to make yet another part to sit inside of the cover to stiffen it up in the vice:




Here it is after machining the second setup:

Similarly, here's the power-valve cover:

Setup 1:


Setup 2:


The clutch cover takes three setups. Here's setup 1:


Setup 2:


And finally setup 3 for the oil fill port. This takes another angled fixture:


As you've probably noticed, it takes a few custom parts (fixtures) in order to make the part your interested in. Add this to design time, programming time, material costs, anodize costs, etc. and you can better understand why one-off part costs are so expensive! Or why no companies are really chomping at the bit to make your 1996 CR125 ignition cover (or substitute whatever random part you'd like here).

Here are all three covers (well, 6 really, top and bottom of each) machined up and ready for anodize. These went off today and will be ready to go next week:
