Here's my current intake setup on the Laeger. Pro-Tect airbox (designed for LSR frame), 86 OEM boot, metal pipe, 2" diameter rubber hose to connect metal pipe and carb, sphynx cylinder, vforce, UPP boot, 38mm PWK

You can see how one of the front mounts doesn't line up. I think the LSR subframe is narrower in this section

Plenty of clearance for the rear shock even when I stood on the grab bar (240 lbs)

TBONE, how does the LT500 boot fit? I was curious if fit any better or worse? It would still need an extension like the stock. Where the indentions are on the stock intake tube are pretty much pointless, since they are there to clear the stock frame... If you don't have one, I could send you one and we can see how "far" off it is then use it as a baseline for a new intake. Just looking at the pics, I was originally going to use my intake I just created but I think the LT500 might be a better starting point.

I haven't even bothered to try the LT500 boot, simply because my airbox uses the OEM 250r boot.

I'd be more than willing to try the LT500 and/or the intake you created and test fitment for you

Tbone, here is a start of the layout of the design. This is an overlay with the one I did for the CR500 and Stock link bikes. (Similar to stock). I was curious how much longer the intake tube is (extension)?

I also tried to move the filter (inlet) side of the intake more to the center, so the filter doesn't sit at such an angle. I may have to go back to a smaller filter so the brake doesn't hit the box, since these are much farther back in sub then stock and CR500 linked bikes.

I was also wondering if you could take a side pic from the left side of your bike. I thought there was one on here but I couldn't find it.

Here's an older one with no engine installed. I can take a better one tonight after work if you need. Bike is all together now

The extension i'm using is about 2.5" long, i'll take a more accurate measurement after work. There's a lot of combinations of intake boots, carbs, and manifolds. It would be tough to make it a one size fits all application

True but we'll start with your no-link and work from there on others.

Tbone07 · « **Reply #22 on:** July 21, 2015, 09:14:16 AM »

Is your plan to make your boot clamp directly to the carb? Or will there be a connecting piece of rubber hose?

troybilt · « **Reply #23 on:** July 21, 2015, 09:44:10 AM »

the intake would fit right up against he carb, there a rubber boot with 2 hose clamps to join them.

Please forgive me. I don't want to say anything negative.....TBONE you have the ultimate no-link set up. Raised upper shock mount. ADJUSTABLE...lower mount and the shock moved far enough to the side that you could drive a trophy truck between the frame rail and the shock.
Troy, you seem to be on the path to something that a lot of no link 250r riders really need. You have the smarts and the tools to make the intake boot that is needed for a no link set up with the upper shock mount in the stock location and centered in the frame with enough clearance at the air box for the shock to swing waaaay back.
If I am off base please respond with two words "YTMAN you are way the efff off base"
I have figured out a system that clears everything through the cycle of travel and has no air gaps between the air filter and the carb but I'm sure there is a better alternative, especially in the performance department. Everything seems to either rub on the frame, the shock, or need 27 hose clamps and a couple more trips to Lowes.
I'll post a couple of pics of my P.O.S. if it will help.

Yes please do. I'm drawing one up now. Would like a pic from top and one from left side, then anything else that maybe important. It's going to be a challenge to design based on pics so there will be some trial and error, but saves me from trying to locate a local no link.

Looks like Tbone07's setup the offset shock was quite the advantage, looks like that is what saved him from having to move the box back. LSR's shock is dead center, not sure about Roll. If I can remember, I will take some pics of my setup this weekend and post them in this thread.

This set up is on a cr500 motor but the carb outlet is in the same place as my 250r.
The stock boot actually wound it's way between the frame and the shock a little nicer up front but the shock moves so far fore and aft that it hits the boot in front and back.
This is the lt500 boot with the adapter in back and a spacer in front. It's mashed up against the frame at the shock but at least it doesn't hit any moving parts.
This is a Laeger frame with stock upper shock mount and a Roll no link swinger. I don't know the shock length.
Tbone, those are awesome pictures. I wish I was home right now so I could take some better shots. I'm limited to what's on my computer.
Troy, you're definitely gonna need a real world model to work from. I wish it could be mine.
Oh yeah... Thanks for the brake line clamp mount idea Troy.

Awesome thanks ytman! ....I thought that airbox mounting system looked familiar.. LOL!

ytman · « **Reply #29 on:** July 23, 2015, 06:03:35 PM »

I wish I had a pic looking toward the carb from the back. The boot needs to be a tall skinny snake to get through there without hitting anything.
Troy, Lemme axe you a question. "would this help" Now lemme explain.
My next step, based on my limited experience in parts creation. C'mon 3d aluminum printers!!!!!!holy crap. Was going to be to sculpt a solid boot out of foam and wrap it with casting tape, as in plaster. That would make 1 part but the model would be destroyed to get the part....If a plaster/fiber casted boot, like broken arm cast///type sleeve part existed could you do anything with it? could you scan it, or measure it somehow to lay down a plastic part with your plastic spewing machine?
