Bump! This great thread was getting lost in the background, so I thought it would be good to take it back where it can get some more attention.


JohnK6 has given to this forum more information in less than 50 posts than I with more than one thousand!!!!!

thanks for the bump , yesterday I had to make overtime at work, when i got home i was buzzy with reading all the forums here, (damned what a information stands here  ), and i was to tired to make a few postings on the thread

now I'm looking at OCC on discovery  , i like that program,(I hate btw how they're putting in bearings, use a big plastic hammer and hammer it down  (I want to build a real caferacer out of a CB 750 four, with mono shock, upside down fork and a 822 cc borekit(the borekit is laying here for over a year at a shelf ))

[JohnK6]

the 822 kit is a bored original cylinder and for the pistons I'm using original pistons from a CB 900 bol d'or, that way it's a lot cheaper than a 836 wiseco kit  , i will need to do someting on the head (pistons are a little bit higher than the original piston from a CB four) i can't do that myself,  but i know a man who can do it

[JohnK6]

when i started with this bike, and got it fired up, the main fuse went out, replaced it and after a few minutes it went out again, same #$%* happend when i turned the headlight on, i measured the wire harness out, and tackled a few problems, but it still wasn't O.K, original cable harness was to expensive so i decided that i make my own new cable harness



and



all electrical out 




the #$%*ty looking electrical harness

[JohnK6]

luckily making a new electrical harness, doesn't mean you have to do it in the garage so i went inside my apartment (nicely warmed ), and a great working coffee-machine 



materials which will be used



a whole lot of collars  , butt i used mainly a big cable (stripped it off and so i got a lot of small cable's )witch is mainly black with on every cable a number (this one is numbered from 1 to 20)



made a big copy from the manual, notebook and pen needed to tell myself later wich number cable went were

Jesus, now he's making his own wiring loom. My brain's hurting with the intensity of it all. What a guy.

the period i done this was in the winter so i had a little time to spare 

damned and with this post i went from newbie to enthusiast

[JohnK6]

so we went on

the start



cable's i used:

earth 2.5 mm2(there are a lot of branching from earth)
all other 1,5 mm2

lot of soldering and schrinking


it's looking better



after 9 hours of soldering schrinking and so on 

[JohnK6]

after a lot of work now i went fitting the cable on the bike so that i could tape the diverge



and in the headlight

[JohnK6]

and after taping it all it looked this way 






the cable harness took me in total about 16 hours of sparetime, and a whole lot of coffee 

[Tim.]

What did you tape it with?  I may be stripping my bike down and might want to re-wrap my harness.

Self fusion tape 19 mm x 5 m

   My jaw literally dropped when I saw this thread.  This is simply amazing.  I bought a $150 US 750 K4 earlier this year that is being cafe'd.  Your posts are going to help me out big time when I get to putting it back together.  Nice work, very nice work on the harness as well.

STICKY THIS THREAD!!!!

Bloody great post mate, this is exactly what should have been done a long time ago, instead of me making do with the not so good, old materials, you have done well, and thanks....


peace
