Topic: Started on the 1978 HONDA CB750F restoratin project

[newday777]

I like your motorcycle lift HH;does it come from a USA manufacturer ?

Might be Canadian or??? The website doesn't say....

[Ozzybud]

Great Project you have here. Thanks for the Updates and progress.

I am currently doing a 1975 CB400F not to this extent but making everything shiny and pretty. close to factory original as possible.

I own an all original 1976 CB750F0 with just over 7000 miles on it. its just like the bike my neighbor gave me in 1979 with 45 miles on it.He rode it twice and dropped it twice. I rode that Bike all through high school and college. i sold that one in 1986 with 62k miles on it.

I have done some cosmetic restoration stuff on in since this picture was taken, side covers are the correct color now and some new finishes here and there.

The lift is bought from premium bike lift in Canada out of BC
where it's made I do not know
It's a heavy lift and I do like it
The lift does not wobble when fully raised with a heavy bike on it
that's the reasen I bought it not cheap $$$$$$$

That's a nice bike all original, Hard to find these days
The only one I own that is as close to all original is my CX500 Turbo
The only thing on the Turbo bike that has been re done is the Exhaust
Needed to preserve it from rusting out so I had it ceramic coated and it looks like stock

BIKE SHOW
Last week end the Edmonton Bike show was on
The CVMG had a invite to display bikes and the display was 30'x50' and there was room to display 27 Bikes
There was a couple HONDA bikes

Honda Hansel

The Turbo Bike got a lot of attention 

[BenelliSEI]

Is that your K7? Nice turnout!

[Honda Hansel]

Hi
Yes that's my K7
The show was well attended on all 3 days
Have not seen any numbers ..Hoping the meeting on Tuesday will reveal the attendance number
It's nice to see all the spectators smiling when they look at the bikes and all the stories that was told
Only had two guys tell me that the CX500TC was not a turbo bike LOL
then I had to convince them by showing the turbo tugged up under the radiator LOL

Nice work on the K7. I have one too and think it’s a great bike!

[Honda Hansel]

Hi John
That's a good looking Bike
I remember we where talking about the LH front engine mount being different on the 1977
I wish my paint was a bit better
O well cant have it all
Patina has a charm as well
Sure got a lot of comments on the bike at the Show

[BenelliSEI]

Hansel….. I restored that one 5-6 years ago. Pulled the plate off my K8 and put a hundred miles on it one Sunday morning. It’s been sitting, bundled up in the back of my shop for years…. Too many bikes!

[Honda Hansel]

I know the feeling
Also have to many bikes and P make a note on the calendar every time I take one out

Here is a update on the CB750F2
Paint work is all back and looking good
Cost a fortune to have it done.. Looking good and happy
Waiting on the cylinder head to be done at the machine shop
Hoping next week for that
Got a 320 grit ball hone so I can de glace the cylinder for the new rings to seat
then it is time to assemble and repaint the engine
 
Last picture is what it looked like when I got the bikes

HH,
Are you going back with stock pistons?  If so, how much piston/cylinder clearance are you shooting for?

Thanks

[BenelliSEI]

Paint looks really well done!

[Honda Hansel]

Yes John
I'm happy with the paint 
my next step is to restore the tank badges to look as close to original
I'm thinking of doing a transparent gold powder coat over the polished emblem and then paint over and wipe the letters clean
In the process of talking to Impact powder coat (Bruce)and he is willing to do a test run
on a not to good looking tank emblem
hoping for good results

Hi every one been some time
I replaced the valve guides and send the head out for a valve job
found new replacement valves on eBay and the price was OK not cheap
for some reasen the 750F2 super sport is not cheap for some parts (only 77-78 year)
got a set of valve guides from 4into1 and some other goodies

I did some port blending for a bit of free horse power before is send the head out
just lite blend not to open it up just to blend the sharp corners and then I did a polish to smoothed the runners and Vapor honed it nice and smooth   

my machinist Larry at Bel engine did it for me (he only does automotive performance stuff)
the valves and guides are small compared to automotive sizes
honed the guides and cut the seats and did a resurface of the head (47RA surface )so I can use a MLS head gasket
now i can assemble and get it ready for the engine

 Going to order a MLS top-end head gasket from CycleX and a new final drive chain and updated chain tension roller with a bit more spring tension

Was hoping to have it done for spring .How ever just got date date for my shoulder surgery set for March 20 and that will set me back a couple month
Needs to be done any way

[Stev-o]

Just caught up on your project, very nice!   

I have found that a valve job is so important to getting the motor running great after a rebuild. Money well spent.

[BenelliSEI]

Looks great, good luck with the surgery.

[Honda Hansel]

Yes Proper valve seal is very impotent

The valve's on the super sport is bigger then the 750K bikes and they are harder to come by
very expensive compared to the 750K bikes
valve springs are a bit higher set pressure as well

I managed to get valve on eBay and the came from Ontario for some reasen
John you might know about the place selling on eBay called Siriusconing
the sell on eBay and they dont give a place of business

John
Im not looking forward to the surgery at all
How ever it need's to be fixed due to my younger age and I have many more year's to work
Gotta support the HONDA habit LOL

A friend told me a little about carb. kits available from Sirius and mentioned their kits are made in Japan?

I just got  kits that the seller did not specify a brand, they turned out to be Keyster and say "made in japan" on them. I took an OEM needle and set my Mitutoyo calipers to a range of widths and set both needles in the gap, the Keyster needle saw about 1/2 E clip notch deeper at every setting. I would expect them to be consistently richer at any given setting. I did not measure the dia of the upper straight section.

Thats good to know about the main needle
When I do Carb's I all ways use the old brass because the #$%* that comes in the kits can not be trusted
I have gotten kits that had the marking on the jet's and still not trusting them
for the most of time's that I need carb parts I just use the gaskets and O-rings

To me the ultimate way to recycle is to keep using things that are still good ;-).
