CB750 / Oil pump O rings / cylinder head gasket seals
« on: October 13, 2010, 11:19:31 AM »
Hi,

I am sourcing 'O' rings to rebuild two Oil pumps I have. Are the originals Viton or Nitrile? If Nitrile are they 70 Shore A hardness?

( I am getting the small oil seal from David Silvers (the GoldWing type - Thanks for the info Bryan  !!) but the 15x2 AND 46 X 2 'O' rings are really expensive from Honda

Also I think the o rings to use a later head gasket on a non-knock pin K0 sandcast head are 14 ID x 1.5mm thick (Viton) Can anyone confirm this please?  Would a 'quad' ring be better, as I gather the unobtainium ones in the Honda bulletin were square section

Cheers !!! Ash

CB750 / Barrels and head painted or not?
« on: March 07, 2010, 03:58:24 PM »
This is really a message for SteveD. Do you know if Eamon's K0 has painted head and barrels or not, as I think it was part of the same batch of UK750 imported in Jan '70 as mine. I am getting mine bead blasted  shortly but unsure if they were originally painted or not.

Cheers

This is really intended as a bit of bedtime reading for 'UKPete' but if you have not seen it already, it makes interesting reading

CB750 / Is this another Ebay bad deal
« on: February 27, 2010, 02:18:48 PM »
Don't want to mention any names here but I saw some 'K0/Sandcast' tank trims go on Ebay for over 80 quid last week.

Looking into history I saw purchase of mini car trim (as I suggested as a substitute for the original item  http://www.sohc.co.uk/index.php?topic=2464.0)

The K0 / Sandcast does not have the black stripes in it. (interestingly the 'Brighton Show' bikes I think did have the black stripes)

The mini trim in the 'history' was:

Bit cheaper than 80 quid !! and would be enough for several tanks!!!!!!!!!!!!!!

CB750 / Here is a funny story
« on: February 24, 2010, 09:27:38 PM »
Daughter coming home today from Uni for her 21st birthday. Wife getting her bedroom ready and moaning about the unsightly motorbike bits I stored under her bed (actually a brand new set of 4  HM300's and a new front fender!!). Texted me at work to ask where the hammer is to put up a picture in daughters room. Got home - bedroom in state of pristine tidiness apart from a CB750 conrod on the bedside table. What's that doing there I ask, thinking she is becoming interested in my bikes - reply "I couldn't find the hammer but I used that thing instead"    :o GRRRRR !! . It was a knac**red one though so I forgave her  ;). ::)

She also forgave me last year when she came home to find my side covers and airbox drying out in the oven. not to mention in '86 when i bunged my 400/4 crankcases in the dishwasher for a final clean  ;D

CB750 / Red paint on control switches
« on: February 11, 2010, 08:33:47 PM »
Posted this on the US site: Any ideas?

"This is probably one for my UK buddies but here goes. I need to paint the 'Red' on controls of my '69 750K0. looked at my 400/4 ones which were NOS and they are an orangey-red so got a good match, I hope, with 'Humbrol' Gloss Fire Orange (shade no. 209). Question is, are the 750K0 ones the same colour?"

Just glad my right hand one with the black kill switch is very restorable. One went on Ebay NOS for 240GBP this week!!!!!

CB750 / Later gear shift drum and selector forks on K0
« on: February 07, 2010, 01:55:02 PM »
Looking at this Honda Bulletin, am I OK to fit a later gear shift drum and selector forks to give improved shifting.
My bike has 46k miles but I have never ridden it to tell what the shifting was like.

CB750 / Caliper Pin Drawing
« on: January 28, 2010, 08:17:56 PM »
I have had a CAD drawing done for an oversize caliper pivot pin for the CB750K0/K1/K2 if anyone is interested. I am getting on made in Stainless Steel and reaming the hole in the arm and brackets out to 11mm. the standard pin is NLA from Honda and I don't even think Yamiya sell a repro one
