Topic: how to save a cb750 from the garbage dump

[JohnK6]

new contact

The former owner had no key's for the bike, so i had to mount a new contact, i could get thisone very cheap from my cbfourparts dealer where i buy most of my parts for a CB four, because it was damaged.

Also in this picture you see on the back my new chokecable (thisone was for free, the cable and the part you screw in the holder was lose, i repaired it with a little of schrinkinghose (you heat it up and it schrinks )



the reason that it was cheap, a lip was broken of, but on my old contact (with no keys) that part was okay so i changed them





by doing these kind off things the costs stay low

[JohnK6]

new gascable's (the old ones were so rusted even after a week in a oilbath they didn't went smooth)



same for the clutchcable



also checked the timing off the contactbreakers

[JohnK6]

time to lose the bolt and let the chaintensioner to do it's work

I do this cil 1 inletvalve and outletvalve closed  and than 15 degrees after the topmark(cil 1-4) (that one you see behind the contactbreakerplate) the camchain is than on a point were the chain has the most slack, and the tensioner can do it's work

lose the bolt , wait a few minutes and than tightening it




time to check the clearance of the valves (inlet 0.05 mm, outlet 0.08 mm)

when i checked it :

cylinder 1 inlet to narrow, outlet way to much
cylinder 2 inlet to much, outlet correct
cylinder 3 inlet to narrow, outlet to narrow
cylinder 4 inlet correct, outlet to much

[JohnK6]

sometimes on the pictures you can see that i did some things earlier, i wanted to get the subjects that I'm posting as much as possible to be related at each other,

Well, I'm involved in a CB350 resto and still have to take my hat off this guy. The reason? I would have never think of reusing many of the parts he has saved. That's where the merit is. It's fun to do an eBay search, the thrill of the hunt, and finally finding a replacement, but being able to take a rust bucket and turn it into a good-looking bike -even if not pristine- is definitely praiseworthy.


This guy killed me with the paint removal of the wheel. Having into account the price of a second hand wheel, I would have never take the annoyance to strip the paint, with all the nooks and crannies of the spokes. And what about reusing the rear fender? Well, it's painted, it's not chrome, but there is definitely a lot of merit in reusing those parts. In my opinion, that's actually restoring a bike; what I've been doing until know is just rebuilding and engine, polishing some parts, taking parts to the painter and chasing the parts missing or in bad condition. It's a lot of fun though, but I've spent more than 3k euros...



Please moderator, sticky this post. John, you speak german, don't you? If you have trouble translating just write the german term and I will tell the english term that refers to.


Two thumbs up!!!!

[JohnK6]

I know he's dutch -he said so in the first post-, but I have read some german words from him, therefore I guessed he was able to speak german.

[Raul CB750K1]

BUMP!!

[DeLuxe]

Oh man, that is one lucky bike to be brought back from the dead like that!
You've built up a great store of Karma with your tireless work...  may the God of Motorcycles forever smile upon you!

next project was the fueltank.

before


at work i made my own dentremover, which i soldered on the tank, and with a counterweight i pulled the dent  out as much as possible, than i filled the hole which was left with led



after that just a little bit off this is needed

[JohnK6]

first time in that stuff



sanded it off



second time with the stuff 



and now it was time to sand it of with waterproof, and where is water at home?, right in the shower there's a lot of water when you need it 



and the result 

[JohnK6]

my own spraying cabin 



when you do things like painting, protect you're self

and yeah this is me 



and when youre going to paint were things like this, that protects you and also the object to be painted from human grease (for example from you're hands)

[JohnK6]

I'm using spraying paint, (and yeah i now i now, butt my compressor failed, and at that time i didn't have the money for a decent one), butt this will the job,

ground layer



and done



this collar

[JohnK6]

tank in collar



and one more time



I wanted to get some striping on the tank and so i went on

[JohnK6]

 i liked this



on the top of the tank Yeaaaahhh i'm satisfied



butt on the side 

i've made the striping to small, and i didn't liked it



I had an old original fueltank ( just a dent, and a little rost here and there, so i mounted that on the CB), this tank is still waiting for me to get some time 

[JohnK6]

and than she looked like this



time to get her started , when i was trying to do that a few friends wanted to look, and what do you think the bike wouldn't start (she was getting no fuel, my own stupid mestake when i take a look at the carburetors (i had my floatings the wrong side up mounted)

on the picture you can just see the headlight of my Honda crx (imported from USA, by the former owner )



and a few pictures made by a friend of mine



and

[JohnK6]

Good work man!

[cben750f0]

M8 that pipe sounds unreal, you got to be happy with that... well done you must be suitably proud....


peace

[unkle fester]

what exhaust is on there??  It sound wicked.......

[Raul CB750K1]

Congratulations! This is a great post. I'm proficient at mechanics, but painting is not one of my strong points. Your tank looks great for being a home paint. Good work!
