Well I've got a guy hopefully coming by this weekend to test fitment on an LSR frame with CRF motor No link. Then I'd send it to Tbone to try on his bike after that.

I cant want to see these done. Troys airbox design is the best i have seen for flow, fitment, and still provides water protection. The 250R's especially the big bores need that bigger filter like the 06 450r's have. I cant wait to be able to run the same air filter on all 3 of my 250R's. I will be buying one for both my stock linkage and CR500 as soon as they are available.

Way to go Troy.

let me know how the lonestar crf comes out, I need an intake/airbox set up for myself

What is the inlet size of the 450 filter and I assume the new boot?

Awesome work Troy!

I understand these are prototypes but Can these printed boots be used as is?

Off hand i dont know what it is, but its larger than the 250R. And its not tapper. Over all its larger, which gives you less velocity going through the filter element which inturn will pass more air, and capture more dirt. Its a Win, Win, Win Situation.

06+ 450r filters have s 4.5" ID opening. The filter itself is 6.5" long depending on brand. Much larger filter.

The 3d printing can be used. However the material in using is not the best for the direct application. These are ABS plastic and are not great at chemical resistance but I'm working on s coating that would allow ABS to be used for a much longer period of not indefinitely. I use ABS prints on the dyno all the time. I've had a bad experience using a printed polycarbonate intake in which broke on me at the dunes and my new 450 sucked sand and took out the top end. 1500 bucks later... I have a new material called 645 Nylon "bridge" material that has no know solvents (ie very chemical resistant) it's also one of the strongest yet flexible materials you can print. Only downside is it takes longer to print and it ou comes in clear/natural color. But could be painted or gel coated. For the one off obscure intake combos I think this would be the best option. Plus i don't have to count on a supplier to provide parts.

So the inlet diameter is the same as the 250(I've used 4"tube to connect before) There is just more surface area?
I have a big hunk of 4"i.d. hose for this purpose and I was just checking to see if it would work on my new Robl no-link boot when I get it.
Plus I would like to use my airbox if there are no connectivity issues.

Sorry I meant 4.5". Its 114mm.....

troybilt · « **Reply #55 on:** July 31, 2015, 11:15:50 AM »

But I could do a 4" one as well...

Troy, here's a link for you to check out. Something similar. A lot of posts to go through but he had a problem with heat distortion on the finished product. I thought you might find it interesting

Ever get to test fitment on the hybrid bike Troy?

troybilt · « **Reply #58 on:** August 25, 2015, 12:01:00 PM »

Yes I tested fitment up this weekend on a CRF LSR No link hybrid, it was a converted yz426 chassis. The intake I printed wasn't anywhere close. I scanned his bike and I'm working on a new intake but it will be handconed, cause at least for this setup the intake was super long and would be extremely expensive to do with any other material. I'd like to send the original 3D printed intake to some other guys to see if its closer on a 250R motor -nolink setup.

I know Jason's Led no link roll design intake is super long as well Troy. He's 2ndmoto on here you might want to have him get some pictures of it.
