Hmm my setup doesn't seem to be much longer than OEM, the hybrid motors must be quite a bit different

Here you can see how long its going to have to be on a CRF LSR no link. I did a rough quick scan of the frame to lay it out.

Troy that looks pretty similar to the Rolls no link Led intake I saw this weekend, that one was super long and narrow. What shock is the fattest shock body and spring setup available ?

I always heard Elka had the largest shock springs/body. I added some fudge factor into the shock diameters to ensure clearance. From the side view you can see how far forward the carb is on the CRF vs. a 250r, I think I 250r will be somewhat shorter, maybe 4-5" shorter. Definitely not the ideal setup for performance, but it will be better than what I've seen out there. I also thought about mandrel bending some 3 or 3.5" tubing part way or something so the hole thing doesn't have to be coned.

Something doesnt seem right. I have had a couple lsr hybrids and the intake did not seem nearly that long. Maybe yz vs crf or your full bump angle is over exaggerated?

The compressed angle I wasn't sure. the original intake/airbox he had hit the shock, so I tried to give him as much room as possible.

This is an example of where every bit counts. The shock length, stroke, tire size, and brand of shock could all play a roll. I know you are doing what you can. Im simply saying how much of a pain this makes it to be a "fits all" a lot people dont understand that.

troy your image looks like my lsr crf hybrid. the hose I am using is super long

Mike, this intake would have to be pretty bike specific as you and other's have pointed out...

troybilt · « **Reply #69 on:** August 27, 2015, 08:12:32 AM »

Here is a mandrel bent 3" aluminum tubing down to 2.5" intake. This will probably be the easiest for me to make, (i.e. cheapest)... still need to work on the airbox for this one.

This thing damn near needs a plennum near the carb..

This is a classic example of what happens when a suspension guy doesn't talk to the motor guy when designing a chassis... LOL!

That Lone Star no link looks to be the worst case scenario as far as the airbox is concerned, with the raised upper shock mount and the lower pivot on top of the swingarm.
I can see from your bitchen work why LSR made that funky airbox the way they did.

I agree. That shock angle looks nuts

troybilt · « **Reply #74 on:** August 28, 2015, 09:39:45 AM »

Can one of you give me a dimension for compressed shock angle? roughly? I took a guess so I might be farther back than I really need to be. I do have the box designed now forgot to post a pic of the design. Unfortunately I think this CRF no link will be a one-off deal, and I'll have to do a totally different design for other no links... so we'll see if this design work is all for not.
