*******************************************************************************************

WELL, I HAVE DONE IT AGAIN...

... I have jumped into a project bike that I know very little about. But the unknown always proves to be exciting and challenging for me and I like that.

Not long ago, I decided to sell my RZ500 because I got it to a finish point and I wanted to lighten my load of work to just keep the running bikes running. In theory, the extra free time was intended to go towards a couple other car projects and a couple of old Kawasaki H1’s too. Well, that whole plan lasted about 3 weeks. LOL

You can read about that bike here:
Operation: MOSQUITO CONTROL BIKE - Florida RZ500 Project
And if interested, you can read about my RZ350:
Operation: RZ350 REVIVAL

Two hours before I was to meet the buyer of the RZ500 for pickup, I got a call from some guy up the road 20 minutes offering me his 1985 NS400R that he would part with relatively cheap. Florida Title, needs minor work. I’m talking $3K cheap, he said. Okay, he had my attention. My first question was what is an NS400R? LOL Honestly, I had only seen a couple online and certainly never one in person. I told myself that if the RZ500 sold that evening, I would hang on to enough cash from the sale before depositing the rest and go take look at the NS400R.

This is the picture he initially sent me.

Picture 001
Image

I started calling it a “porch find” (similar to the commonly called “barn find”) because I think that’s where it may have sat for the last 20 years. Actually, I don’t know exactly where it sat ALL the years the guy owned it, but he said he had only put 32 miles (or maybe km’s) on it the entire time.

The story on it goes like this… he bought it from someone in California and made sure it had all the proper paperwork (back then, emissions for a gray market bike may have kept him from registering it for road use). Not long after (maybe in 2001), some kids from his neighborhood stole it (I know THAT feeling!!) and tried to get it running. They messed up the fuel tank pretty bad trying to get the cap open (I guess those locking caps DO work to some extent), messed up the ignition switch and added quite a few scratches all over the bike. He recovered it some weeks later and ended up getting a new tank, switch and whatever else it needed.

After selling my RZ500 it took a couple days for our schedules to line up for a good look at it in person. Here are a few pictures from my initial viewing.

Picture 002
Image

Picture 003
Image

Picture 004
Image

He also had a number of spare parts to go with the bike…

Almost a complete spare engine and extra set of cases.

Picture 005
Image

OEM rear wheel.

Picture 006
Image

OEM pipes, the damaged tank I mentioned earlier, and a bin full of assorted bits including barrels and pistons to go with engine above.

Picture 007
Image

Of course, people’s opinion of “minor work” differs. I agreed that minor work was needed to possibly get this bike on the road again, depending on the surprises found. But to get it the way I wanted it, it was going to be MAJOR work. Still, after reading about these bikes and what a joy they are to ride, I was super intrigued and sort of had to have it just to satisfy my curiosity. I owned several classic Honda’s before and it seemed they all were built well, so I hoped that would help ease the restoration effort as well. And besides, it really wasn’t much money to risk.

We went back and forth via text quite a bit and finally I said I would take it if he took care of bringing the title up to date (he had never titled it in his name for the 20 years he owned it). He said he planned to do that anyway so he was now on a mission to expedite that step. I thought I had a couple days to really give all this more thought while he messed with the DMV. He had the VIN check done at his house by a local law official and was off to the DMV right after to transfer the title. He had it taken care of in no time, where I can’t even get an appointment in less than a week in my county just south of him. Weird. Anyway, he did his part and that all checked out, so I needed stand up and do mine… go over and buy it, whether I was completely 100% sold on it or not!

He helped my load it up, but I normally have to figure out how to get things done by myself back at my shop and luckily I have a stairway leading down to the lake that doubles as a decent loading dock.

Picture 008
Image

And here it is, safely at home in The ASYLUM, along with its parts and the big block Chevy project engine that will likely be put on hold a while longer. LOL A drain pan was slid under just in case it decided to leak something while I was gone.

Picture 009
Image

A few days later I successfully transferred the clean FL title to my name and also registered it for legal operation on our Florida roads, so I was one happy NS400R owner at that point.

Oh, and if you are wondering why I titled this project thread "TRIPLE THREAT", the triple part is easy… it’s a V3 engine. But it also threatens to test my sanity, test the depth of my wallet, and test my patience for locating rare parts.

Next will be seeing exactly what a mess I’ve gotten myself into! LOL

Super buy...I think that will test your patience somewhat, I struggled to get parts for mine back in 1988 and they are a more fragile beast than the 500, 'thou of course the web has made it easier since.

Looking forward to your updates on it!

Congrats on the purchase!

I'll be taking notes for sure. I bought a modified one years ago and never did anything with it. Just sits there, looking interesting and taking up space.

Looking forward to another great rebuild.

kpke - We will see what a money pit this becomes. At least the entry point was low. More updates on the way!

lost750GTV - Hey now, be nice! LOL It’s still a 2-stroke, right? I’m trying to make myself more well-rounded. LOL

podman - Patience is one thing I have. It also takes a bit of cash because shipping from Europe or Japan adds up quickly! Yeah, thank God for the internet resources. Thanks for following along.

Smoker - Interesting they are. I’m looking forward to getting acquainted with this one. Nothing looks very complicated at the moment, however, so that is good. I’ll try to give this thread as much detail as the others.

SO LET’S CLEAN THIS OLD GIRL UP A BIT...

It was time to wash off the porch dust and see what’s under there. I was happy to see the windshield was in good shape. The bodywork has quite a few scuffs and scratches and a couple hard hits that I will need to deal with. Unlike the RZ500, I will need to do some major painting on this bike. But that’s okay because I intend to get this bike back to a factory color scheme.

Rims are not stock and I think the rear is from a CBR600. I’m not sure about the front, but maybe I can find an outlet for both of those someday after they are removed. I have the rear OEM rear and I will seek out a front Comstar to match it to go back on the bike someday.

Fork, swing arm, and brakes all appear it be OEM. Fork sliders will need refinishing as the black paint is bubbled up on leading edge. But for me, painting them black is easier than trying to achieve a smooth polished aluminum finish, as on other bikes.

The frame itself is nearly perfect with only minor scratches. The frame is a work of art for its vintage, by the way… Good job Honda!

Both front and rear brakes didn’t work when I picked up the bike. Without any intervention, they both now miraculously work okay after sitting in the ASYLUM several days. Perhaps the bike likes its new surrounding? LOL. I will be putting brake components on my rebuild list, but at least it is not urgent now.

Picture 010
Image

Picture 011
Image

Looking at the rear of the bike, you will see that the rear fender has been cut off as well as all evidence of the passenger pegs. What wasn’t apparent to me because I didn’t know anything about these bikes at first was that the rear side panels had also been trimmed off for an abbreviated look I suppose. It was done in a pretty clean manner though and what’s left is in pretty good shape overall, including the left side helmet lock door. The side panels will be a major decision point for me… source some better ones or just run with what I have.

It’s too bad I just bought tires for my DR650 lately because I believe the rear dual sport tire will fit perfectly on it. Oh well, now I will have a spare. And until I replace it, it might work nicely for testing bike around the yard!

Something definitely needs to done with that mismatch of the upper silencer in the body exit hole. I likely will go back to the OEM pipes, so that may be a non-issue.

The seat pan appears to be stock, but there is a different profile cushion and cover on it that I would like to change out someday. It does, however, feel pretty good and the deep step feels like it would support the rider well under hard acceleration. Again, its usable as is, but will go on the wish list as I search for reasonably priced parts. I see plenty of seat covers on Ebay, so I really just need the stock profile foam (or maybe this one could be reshaped?)

Picture 012
Image

The nifty little helmet lock hatch below the seat works nicely and all parts are there. This bike has a tiny chain compared to the one on my old RZ500. I’m guessing 500 was bumped up when the FZR wheels were installed.

Picture 013
Image

The front fairing stay definitely needs some tweaking to get those mirrors symmetrical again. Mirrors appear to be OEM and pivots are nice and tight yet. I have no idea why they are dull white though, so they will get repainted.

If you look closely, there is a crack in the front fairing left side (right in this picture) near the handlebar bulge that needs to be repaired before a re-paint.

Picture 014
Image

This is a very narrow bike. This is another good vantage point to see the upper silencer mismatch. If keeping these chambers on, I have a slick idea how to make this upper one look more integrated.

Picture 015
Image

The cockpit is showing 36,226 kms (22,641 miles) on the clock. Gauge are in decent condition. The temp gauge has a little cloudiness on the backside of the glass, so I need to see if this comes apart for cleaning. Top triple clamp will need re-finishing, but it seems many have some sort of key rub-rash on them anyway and likely I would be working on that no matter what bike I bought in my price range.

After-market clip-ons are installed so I will need to seek out the OEM versions. These are fully adjustable, so I may still clean these up to use if I find out OEM are not as comfortable. Switchgear is not terrible and red stenciling is still all intact. I think I can bring back the left side with some 303 Aerospace Protectant (great stuff!). The master cylinder took a shot at one point, so I need a new cover.

Interesting story on the little cover between the triple tree and indicator light module… I was looking the bike over closely and noticed something down in the side fairing. Lo and behold, it was this cover. It made the trip home on the back of the truck without going airborne. One less thing to buy!

From this vantage point, you can see the piece of the front fairing that has broken away on the left by the windshield rear edge. That will be a tricky fix, but I have several ideas on how to solve it.

Gas cap needs to be black. All triple tree black plastic caps are there… sort of amazing.

OFF COMES THE BODYWORK FOR A CLOSER LOOK...

I was pleasantly surprised when I took the bodywork off. Not only did it clean up well, but most everything appeared to be there and unmolested.

All heat shields are still there and in nice shape with the foil on yet. It’s missing the right side electrical connector cover above the engine, which is non-essential, but would tidy things up a little. The seat latches are not latching the seat in, so I need to address that. Someday it would be nice to paint the engine cases, since paint is flaking off.

Other than that, I think it’s in pretty good shape. Maybe a little black paint here and there on the brackets. I’ll just let you look at the pictures as there is not a lot to say.

Thanks for the tip! Yes, I need to keep that in mind as I search for the parts I need. Broadening the search can only help find better and/or less expensive parts.

LET’S SEE WHAT SPARE PARTS CAME WITH IT...

I’ll admit, I had a blast digging through that bin of old parts to see what goodies it contained. It was even fun exploring the nearly complete spare engine because the cases where split and I could see inside and learn more about it. I never got that chance on the RZ500. Some would consider it lucky to not have to tear an engine apart, but I consider it sort of a lost opportunity to learn something new.

Here is the spare engine which has a broken #3 rod. A quick look deems the cases okay and without damage from cylinder #3 carnage. The clutch and transmission look to have many useable parts in it and spins freely. I sprayed it all down with WD40 to eliminate any additional corrosion.

A second set of cases, without holes and possibly useable. A few bits were still inside, including the potentially failure prone middle shift fork.

There were a bunch of NOS OEM gaskets, head and barrel studs, and other various bits, like someone was collecting parts for an engine overhaul. These could prove very handy someday.

Quite a few more chassis related NOS OEM parts. I believe enough brake disk bolts to do the entire bike, a bunch of spacers, and even the turn signal filler plates that insert in the front fairing. The second set of CDI units need to be swapped in when the engine is running to test them out. Maybe I will get lucky to have a working spare set. Extra helmet/seat lock and latch, and new axle nut.

I jumped for joy when I saw the kickstand fairing, albeit a bit mangled. At least it is something to work with. I believe perhaps that it might have the original paint still on it too, so that might prove to be a good paint matching item. I was also happy to see the toolbox because its nice to have a place to store registration papers along with essential tools. I will still need to seek out the right side fork cover, but at least I have the left, and without any cracks. The prior owner said he bought the indicator light module after the bike was stolen because the original was damaged during the theft. Unfortunately, the label letters are barely visible anymore.

This looks to be the remnants on some UNI pod filters. Also one of the rear grab handles. The rest likely didn’t come from an NS400R

Some old carb parts could come in handy in a pinch.

OEM rear wheel definitely will go back on the bike. I need to acquire a front one as well. It appears to be in really good shape.

OEM chambers seem pretty much indestructible, but silencers have some road rash and dings. I have an idea how to re-skin them cheaply, however with SS or aluminum.

OEM tank that was replaced after the theft. Someone pried on the filler opening and bent it while trying to open the cap. This wouldn’t normally be useful from an esthetics standpoint… UNLESS… I end up buying one of the Chinese body kits that include a gas tank skin. This would be a perfect candidate for that. More on that plan later.

Non-NS400R turn signals, but ones that could work temporarily on the rear. I believe the two with the brackets were, in fact, the ones used on the rear of this bike after the fender was cut off.

And lastly, some other bits that I don’t believe came from an NS400R.

Wow. You scored big time with that deal. The spare parts are gold in itself. Several NS400 owners here and I've had mine disassembled down to the last nut and bolt so I'm sure we can answer any questions that might arise. Looking forward to seeing your progress with it.

In Germany there's an interest group of NS400 owners lead by Frank Daum.
I guess, if you need any special infos, they'd be able to help you out.

2manyprjx - Yeah, I think I ended up with a great starting point here, but it will be a lot of work to get it to a level I want. It’s great to know I’ve got support like you if I get into trouble (maybe I’m already there? LOL). Thanks for the offer and letting me know.

MK - Luckily Google does a great job of translating, because it’s been a long time since I had to decipher any German! I have not stumbled upon that website yet so I will check it out. Thanks for the link, I will add it to my reference list.

tacky1 - Yeah, great bones to work with. I just pulled the rear wheel off this weekend and the axle was lubed enough to ease disassembly… someone was thinking ahead for the next mechanic. Thankful for that!! Everything that I have encountered thus far seems to have been touched by a competent mechanic. I will try to continue that theme!
