350X 400EX Transplant Build!

[RIDE-RED 250r]

Just be sure that nothing hits the tank when the rear suspension is fully compressed. Looks real good.

I did check, it has a lot of clearance.

Shouldn't be too long until I fire this thing up!

Excellent!! Can't wait to see this build come to fruition

Finally got the cross member cut for the oil tank mount.

And this is where it goes, just need to get it welded on. This will allow me to mount the oil tank and air box.

Been tied up the past 2 weeks with family stuff. Made some progress today. Got my mount bar welded and drilled the holes in the tank mount. Also bought a new wiring harness. Old one was hacked and I didn't want to deal with it. Next up is making the oil lines.

These are not the final bolts to be used. Just for mockup purposes.

I have not been idle on this; the oil lines were harder than I thought. Originally my plan was to have some nice lines made up like the hydraulic crimped factory ones. When I looked into that option the fittings were expensive and way too bulky to fit where I needed them to go. For inspiration I looked up people who had put dual coolers on their 400ex. What I saw were people just cutting the fittings off and hose clamping to the tubes. I couldn't come to grips with that solution as I've put too much effort into this to risk my engine life to a clamp on a smooth surface. So I set out to find a way to get a barbed end on.

My first attempt was a crimp on style fitting. Unfortunately the fitting just ended up being too long and would hit the frame. So then I sent the fitting over to a machine shop to have it remade into something I could thread a barb fitting onto. That option was too expensive. But they did manage to Solder a barb onto the end. This will allow enough space to hook up my line to the rest of the system. I'll be using the stock oil cooler. The crimp fittings will work for that part of the equation. Enough talking, here is the first peice of the puzzle

Made some progress on the oil cooler lines. Soldered on a brass fitting that will allow me to put a barbed fitting on.

Figured out I also have to modify my PRM skid plate because the lower oil port on the engine hits it. I'll tactfully cut a hole so it will clear.

awesome build.. i want to do the same thing. Im interested in drawings of your motor mounts! I have a 400ex donor and a 350x rolling chassis..

how are you doing with this build? i see it has been almost 3 months since an update!

I've got the CAD drawings at work. I'll see if I can attach them here. Life has definitely gotten in the way of this build. I hope to start it back up once I start burning wood for the winter. I got in the last electronic part I needed. I bought all new wiring and electronics except for the CDI and coil. But the harness, switches, etc. Are all new.

The engine mounting s the easy part. Be prepared for issues once you get to the oil system and the pipe. I'm pretty much over the oil hurdles but now I've got to modify my air box. I'll have to get the pipe welded up too.

Very nice build can't wait to see the finished product. I've done many stock restorations and I know what that takes, I must say very impressive to do the same plus these additional modifications. No guts no glory right?

Its actually nice to read a legit thread where people know what they're talking about.
