The steering lock in the ignition lock usually means it was a U.S. model, but you can be sure by checking the frame/vin plate. The relays to the headlight were probably to allow the use of a higher wattage headlight bulb without putting excessive load on the existing wiring and switches.

I've never understood the system with the frame numbers. My frame number indicates that it would be General Export, Australian, German, French, and so on.. 1051697.

A little bit of progress.. Just pulled the engine out today. Need to decide what i wanna do first, the engine or the frame. Might end up disassemble the engine to find out what parts i need, and then move on to the frame while i search for parts. Saw that cruzinimage doesn't have any 466 kits for the 400f at the moment, heard a lot of good things about those.

So disassembly, cleaning, measuring, order parts. And then clean the frame up, blast it and paint. Fix the wheels and front end so i'll have a rolling chassis to set aside. Going to get a new wiring loom and consoles from DSS. Was quite happy with the quality on my last bike.

Welcome to the forum Wiinberg.
There's nothing like a motorcycle project to keep you busy over the winter  :D.
Good idea to get into the engine first to see what needs replacing.  If the engine is in reasonable condition and can be repaired the second thing I would do is to drop the chrome and zinc plating off for refinishing.  Chrome plating in the UK can take an age to get done. Take lots of photos of what you are sending away though, make a list of everything, photocopy it and give one copy to the plater and keep a copy for yourself. Make sure you clean the bolts and file the burrs off.
Good luck and keep the photos coming.

Thank you! And thanks for the tip about photos and a list, that's a great idea. Just had an hour to spare this evening, so started to take the engine apart. Oh boy. Bought it because of the low mileage, but this engine sure has seen it's better days. 4 different types of bolts keeping the rocker cover on, threads coming out of the bolt holes, couple of helicoils here and there.. And the cam chain has eaten a good part of the cases. Not what i wanted to see. Really hoping that i don't have to change more engine parts other than the cam chain system and new bolts. As a student theres not much to spare in the budget. How do you guys get the head off? Just a couple of punches with a rubber mallet?

Its a shame some butcher has been in there before you, stripping threads and whatever else.... hope you can sort it out. How cheap / easy are spare motors to get hold of? Might be worth investigating before spending loads on that one..... Good luck mate !

Not that easy around here. And i sleep better at night knowing what parts are in my engine :) But could see if i can find a new head in good shape. As of now, i've noticed at least 5 bolt holes with questionable threads.. Too many for my liking.

 Thats going to need the camchain horseshoe and other associated bits but the rest looks reasonable, look up timeserts and/or keenserts which are great as long as you have the metal around the hole to take them

Our old 'buddy' bikepusher has an original 'horseshoe' . Pretty rare part to find in original design and decent nick.

He gets away with it because eBay allow him to. Have just tried to report the listing to eBay and no pull down menu is available to describe this violation nor any way to write my own. Therefore eBay must agree with this sort of practice. Nice one eBay!!

To be fair he probably just copied another listing ( I have done it myself) . In his defence he starts things off pretty low ball and as much as I hate breaking up good bikes I am guilty of buying parts that I know have come from bikes that should never have been broken up. He does have some nice parts and for the main pretty honestly described. Never bought from him personally except that I did bid once on some nice 400/4 bars he had listed  but got outbid at silly money. Also he did make some good contributions on here (amongst the ranting and upsetting Bitsa (RIP))  ...such as describing  the markings on 400/4 silencers and 400/4 seats on the last available Honda stock vs original bike fitment. He came over as a bit of a' know-it-all' ..but people on here have accused me of the same on here.  In a kinda perverse way, I miss him on here like I miss his nemesis Bitsa.

BTW he describes this listing as having 'one of those horrible' filler caps ... like the one I sold to a Japanese guy for 100 quid!

An "almost fair" review Ash.

I kicked him out because he refused to change his behaviour and stated that he didn't need a "low traffic site like this"  :(

Low traffic maybe, but what the marketing world would call "a goldmine of interested parties"  :)
