My frame came this past Monday and I picked up some parts from Jon who I met here on the forum.

I set the parts in the frame and I think I have a pretty good start. I have a long way to go, but I enjoy searching for parts and good deals.

This will be a labor of love and take a long time, but that’s what I want. I have a bike for riding, this is for building.

This is the frame when I got it Monday and below are how it looks after some parts were fitted. I have a few more parts coming next week. I’ll keep you posted!

I’m pretty happy.

Nice progress.

If you are going to build a fairly stock bike, you need to fit the (oem) horn about NOW,
it can't be done later !

Once I got my Norton apart, I never put the horn back where it was mounted. No frickin' way.
You can see where it's mounted in this pic.

Right behind the right z plate. This pic was taken in 2010.
Nortons rule.

Begs the question where is the horn supposed to be?

Up above the swing arm behind the gearbox, wedged in between the fender. What were they thinking?

Good answer Bill !! (Edit. which has changed since I posted this comment...)

Its so long since I've seen it I can't describe it precisely, but its in behind that z plate,
under the battery carrier - and beyond all reach !!
Buried so deep, it does sound a bit muffled - but is a good rich note.
I had to drill the rivets out and clean the points to get even a squawk out of it.

To be fair to Nortons, previous versions were heavy and prone to cracking their mounts,
so Nortons obviously (?) thought they'd solve this bogey once and for all.
And mounted it where it can't possibly fall off... ?

Someone somewhere posted this, although I can't vouch if this covers all models and years ?
Photobucket too, so its no guarantees it will even show.

I believe the horn with a mounting bracket bolt to the back of the battery box. You have to remove the rear fender to do anything with it.

I have seen horns mounted behind z plates and on brackets off air cleaner plates. I mount them on the coil bracket up under the front of the tank. Use a hi and a low Fiamm freeway blasters with a relay and you will get some attention.

Now the bad news, which you may already know, your fiberglass tank will fall apart in a hurry with this modern gas. Put it on the shelf in the dining room and buy an Emgo and have it painted.

What he said. This happened when they sneakily started putting ethanol in our fuel. Lots of boats with fiberglass tanks had to be rescued by the Coast Guard. Boat motor sales went through the roof.

There was fiberglass resin goo all up inside my carb. The bike wouldn't even run. Not that I wanted to be riding around on a Molotov cocktail anyway.
Leprosy!!!

A local Norton guy in the 70s put a Dunstall seat and tank kit on his bike, and removed the rear fender. The horn promptly dislocated and jammed itself between the wheel and the swing arm with predictable results. Didn't hurt much more than his feelings as it happened in town, but had him off on the street in the traffic. Funny in retrospect, but very scary, very real when it happened.
I removed the horn from that location on the 850 I've just finished, and it's not going back on my watch. It had rattled around in there for a while, must have made a hell of a racket too.

Well at least my bike is completely apart. And yes, based on what I’m reading, NOW is the time to buy a horn and install it.

I am not keeping the fiberglass tank, I haven’t bought one yet because I can’t decide between the Roadster or the Interstate.

There are a few steel ones on eBay, but I need to make a decision.

I’ve gone back and forth many times. I’m back to Roadster, but I was convinced on an Interstate, so who knows.

I would buy a different horn and mount it where you can easily get to it. I used a BSA style horn and mounted it between the coils. As far as the tank goes, if it's an around town bike Roadster is better looking but Interstate has more crusing range for long distance.

This is going to be a fun bike not a long distance bike. If I want to take a long ride, I’ll take my Ducati.

I took a regular automotive horn & L-bracket modified to accept a leftover hootus(mount for exhaust because can't recall name) and put it at the front of the battery box below the K&N's. Looks alright, fills the void somewhat, loud as hell, easy access.
Split the rivets to disassemble & clean points for revival of original, eh? Sorry for the brief diversion but appreciate this bit of info. Best of luck with your build.

P.S. It looks like your basket case has had a roller bearing upgrade to the swingarm pivot,
grabbing the pics from elsewhere.

You'd be well advised NOT to undo that ??
My (ahem) BM has done 200,000 miles + on the oem taper rollers, with nothing more
than the routine greasing and setting the preload.

I appreciate that, but it’s going to be too big of a project to find the correct swing arm and use this set up.

I’m going to a standard MKII swing arm and bronze bearing.

Anyone want to try this roller bearings setup?

Yes I thought that might be.
You could possibly enquire with the seller of the cradle as to what happened to that swingarm ?

I'm in about the same boat.
I bought a swingarm with a needle roller conversion, but didn't get the (hardened?) pin that came with it.
I'm not sure that the stock one will be sufficient - haven't explored that yet.
But a stock one (swingarm + sintered bronze bushes) will do in the meantime.

What's up with these swingarm upgrade posts and what forum are they being posted on ? Why not just tell us where the pics came from Rohan? We have a carryover conversation appearing here from another site which many of us here and as related to this thread are unaware of. Please bring us up to date.

So I’ve come a long way in what I think is a fairly short period of time. I have a lot of parts and I’m picking up some more in a few weeks. My goal is to have a roller that I can park and begin working on the engine.

I’ve installed the correct horn bracket on the back of the battery box and I’m going to install the horn now while it’s all apart, that was great advice.

Jon your parts worked out great, thanks. A little paint and polishing and they look like new!

Take a look, I’ve also added some frame security!

I also changed the cradle with the roller bearings for one that is correct for the bike.

Be careful what you buy on eBay, I thought I bought a regular cradle, just to find out that when it arrived, it had roller bearings. Anyone need a cradle with roller bearings?
