General Discussion / Silicone brake fluid.
« on: April 02, 2023, 03:21:28 am »
I was on some forum or other and I can't remember what one it was but it was CB750 related. Everyone was saying use silicone brake fluid. Non hydroscopic and it will last forever. Well, old dumb##se here decided to use it. It seeps out of EVERY join in the brake system. Right down to going past the O ring that holds the piston so the crap goes out onto the brake pad on the left hand side. This was a 100 point restoration of the whole front brake system right down to black anodizing on the splitter. I despair at my own stupidity sometimes. This isn't the first time I've seen stupid posts on bike forums. For example Q: My bike runs like crap. A: Tear those carbs down right NOW!!! Rant over but hopefully someone will learn from my mistake Peace out.

Parts Wanted / Re: Orange foam scraps wanted
« on: September 24, 2020, 02:45:03 pm »
Thanks for your replies, men. I have a reproduction yamiya750 seat with white foam that I will put on the bike. I'll just continue on with the restoration and keep looking for orange foam. I'll try the SOHC forum and also Facebook pages I'm subscribed to. I messaged Ayako at Yamiya to ask if they had any scraps but I've had no reply.

Hi, I'm kicking this thread back to life because I'm not prepared to put my seat foam back on the bike in its current state. It's dry and flakey and it will just go everywhere if I don't fix it up. I need some scraps of orange foam to glue over the holes before I get it recovered. Can anyone help me out? I only need about 6 square inches X 1/4 inch or so. Many thanks, TC.

Brakes / Re: What does the correct brake rotor finish look like?
« on: August 26, 2020, 03:21:52 am »
I had my rotor spun and treated with coarse to fine grades of garnet paper then I masked and painted it. I used Metal Rescue to get rid of the brown rust scoring deep in the metal. Two hours to mask and ten minutes to paint with a spray can.

Brakes / What does the correct brake rotor finish look like?
« on: July 17, 2020, 12:06:52 am »
I want to get both faces of my rotor machined smooth as they don't look too good. Does anyone have an image of what the finish should look like and also give me the name of the process so that I can phone around the engineering shops in town to see who can do the job for me.
I'm going to retain the black paint on the inner part but does anyone know how to clean up the rusty looking inner ring that has the chromed domes?
Many thanks, TC

Fenders (mudguards) and Seats / Re: Forming tool for damaged stainless steel seat trim.
« on: July 01, 2020, 07:45:14 pm »
Hi Sam, the tool was purpose built from an old 8 mm Ajax bolt and some square section steel rod. The guy that I borrowed it off made it specifically for his Suzuki Stinger T125 seat trim. It worked perfectly for me. I gently tapped the bolt part along the folded rim of the trim and it just magically pushed the part back into place. There was quite a bit of dickering around of course but the tool worked very well.

General Discussion / Front fork differences in sandcast and diecast K0
« on: June 30, 2020, 10:21:39 pm »
I have these two sets. The stepped ones are off the November 1969 diecast I am restoring and I will be polishing them for installation. I've seen on this forum that all sandcast bikes have stepped.
The tapered ones shown take sandcast guards. They also take 1969 and probably 1970 diecast guards so at what point did Honda transition to tapered? I believe that K1 forks are completely different.
I will be selling the tapered ones as "fits 1969 and 1970 Honda CB750"....
Also, I believe there is a third type which are similar to the tapered but they have a shorter taper so they are a cross between the two. I would be interesting if someone posted up a picture of that variation for reference purposes.

Hello all,
Yamiya (I think it was) used to sell rolls of orange foam that you could place on your seat pan prior to recovering. There's none on their website now. If anyone could sell me enough to cover the holes in my base I would appreciate it.There's just the three holes at the rear under the ducktail and then a line running down the middle. Also, should the strips of foam running left to right above and below the orange strip in the middle of the seat be creamy yellow or white for a 1969 diecast? Many thanks, TC

General Discussion / Re: Do I have a fork'n problem
« on: June 07, 2020, 11:01:42 pm »
Thanks for your response, Sam. By a massive stroke of luck and coincidence I have been offered a NOS pair, a left and a right hand side, so I just wanted to make sure I knew what I was buying was correct. I pick them up later on this month.

General Discussion / Do I have a fork'n problem
« on: June 07, 2020, 12:06:37 am »
Hi guys. I need to replace both front fork covers on my 1969 diecast as they are damaged. Are these forks correct for a K0 or are they later ones that fit? i.e. K1 Note the cast flange on the left hand one. For interest I have added an image of the dry biscuit like crud that was on the bottom of one of the covers. For some reason the pictures are very large when you click on them. To reduce the size press down on the keyboard key "ctrl" at lower left and use the middle wheel on your mouse to scroll up and down in size.
