Honda CB750 Four K7 1977 entisöinti, linkit

This took more than 5 minutes.

WD-40 is excellent for cleaning carbs.

Not wery cheap but I think worth every cent

The old one hasn't been accelerating anything for the last 20 years, it was so stuck I had to use a small hammer to get it out. Also known as diaphragm or membrane pump. This is one of those many things that separate K7 from earlier models, they dont have it. I do.

Nobody wanted to buy this old seat at a swap meet and it pissed me off so much that I restored it completely and sold the new plastic replica seat at a swap meet. Rusty from top..

...to bottom

I mean very rusty

Never seen rusted leather before

Removing rust with electricity, very effective, called electrolysis

Also the paint took off, which was nice.

Rust is gone but now there is a black coating that has to be removed before powdercoating

Not bad, it starts to look like a seatpan

Nothing is more important than well organized working area

Seat also needed some refurbishing, I used canvas.

Pan was broken from both sides, too thin to use MIG-welding so I used spotwelding. Here You can see how the rust is removed from those badly corroted places by electrolysis

Support piece in place with locking pliers

Never done spotwelding before and if I can do it anyone can.

Waiting to be powdercoated

Well this wouldn't rust anymore

I had to use glue to attach the new seatcover, the old fasteners were too worn out.

It was much harder to find the chrometape than to attach it

That's it and I hope I never ever have to do that again.

Camchain and tensioners were worn out

and as You can see CMSNL-image

This is what it should look like, the original image of Honda CB750 K7 1977....

..and this is what it really looked like, yes I know it looked rather nice from distance...there are still these moments when I wish I'd kept my distance..

..and this is what it looks like now after 13 months.

First paint then stripes which are like big stickers (and by the way wrong colour for this bike, thank You germans, that orange stripe should be red) and finally lacquer paint, yes I know should have bought new emblems also but 70 € a piece, I think these do just fine, at least for a while.

Lot of cleaning, perhaps sodablasting and of course painting and that's only the outside...

a rolling chassis

After sodablasting and washing it looks much better

Standard pistons are in good condition and after thorough cleaning look like new.

Example of oversize piston

After sodablasting

Cylinder before sodablasting...

..and after.

After sodablasting

After painting...

After Tig welding...

When assembling the lifterplate, put two longer bolts to opposite holes and pull the clutch together, hold it there and put the original bolts to those empty holes and gently put some pressure to the springs , done this replace long bolts with normal bolts and start tightening 1/4 turn/bolt.

New exhaust and mufflers, ordered from CMSNL, had to say that because I use their image, new bolts, pillions with brackets and of course these are totally different than those on K0-K6

This kit is a very good choice

After assembly the clutch was sort of slack and we found out that one plate was missing, that nr.6 called plate B doesn't include to the clutch kit, so we used the old one.
