Topic: '76 750K: Project Gunfighter

[Greggo]

Before:


After:


I still love my 500/4, but I've been jonesin' for a 750 lately.  Well, here's my fix.  1976 CB750K. 36k miles.  Corbin Gunfighter seat.  Nice Jardine 4-2's.




Here's how she looked when scooped up off the streets of San Francisco with a free sign on it.  Fellow Member Domer picked it up, did some work, and sold it to me later on with the Corbin seat, a tank, and a few other things..



Flash forward to when I got her...
Jardine 4-2 exhaust.  I need the clamps at the head.




Stacks will be sold eventually.  I need an airbox with the boots.


The seat is obviously the star of the project so far.  It's the first one in Corbin's run of the new Gunfighter seats.  They made the seat using this bike.


16" Harley rim laced to the 750 hub.  I will probably source an 18" rim.  If I can get the spare wheel from my '71 500/4 to work I will do that.  I imagine I need a different brake plate and spacers...



Front rim is in great shape.


Tank is incredibly clean.  These shots were really hard to get.

You have a great starting place for sure.  Good luck and keep posting!

The seat is new to Corbin?  I love it and cant find any info on it.

The bike is in great shape! I love that seat. I think Corbin calls it tuck-and-roll stitching. (some people made comments about the choice of stitching on my Corbin cafe seat (74 CB750), which was also a prototype    ) 

I have been going to Santa Clara Cycle Salvage so much lately, that the guys there have become my friends. If you want, I can talk to them about the parts you need, and I am sure they will be willing to help. I had to get most of those parts as well for my (numerous   ) bikes , and they were available from K+L or Parts Unlimited... same day or the next day delivery.

When you finish the bike, come out for a ride/breakfast to Alice's. My friends ride every Sun in Santa Cruz mountains, it would be great to see more old school Hondas. Last week I met a guy on a CB400F and his son was riding a CB200. Both bikes were lovingly maintained/improved upon.

Somesuch, always nice to meet another Bay Area rider (especially a SOHC4 rider!).  If you talk to those salvage yard guys, I'm looking for nice front/rear fenders, maybe some shocks, an airbox, and maybe a rear wheel.  My pops is saying I should wait until he gets her titled before spending anymore money...but the title is just a matter of time - it won't be a problem.  The bike has never been registered in California, and CHP said it isn't stolen.  Worst case scenario, we have to lien sale it through his shop, which means an extra 50 bucks...not too bad.

I wish I had Sundays off to come down for a ride.  I know there's some great riding roads in them hills But, Sundays are my money days at work - best pay rate, and a relaxed work environment.  I can do Saturday afternoons tho! 

[Greggo]

Sweet, rebuilt shocks off ebay for $25.  Guess I can knock that off the list.  They're off a '73.

[somesuch]

The reason that we ride Sundays is because my friend is off Sundays and Th......so Th is an option

[Greggo]

Can't do any real work until the bike's at the shop next week, but I wanted to do a little more digging, and wouldn't you know I found some dirt.

All D8EA's

#4 Plug


#3 Plug


#2 Plug - This one was a B(^$H to get out, but was not stripped.


#1 Plug


Nasty


Nothing alarming here, but I'm not sure what's capped in that yellow plastic top.


Looks like the whole motor was polished at some point. 


I bought some chrome, finned side covers from SeanBarney.  Those will go on eventually.


I disconnected the Triple A ignition switch mount to try and get rid of some of the rust.  I also need a replacement switch, which is pretty high on the list right now.  The Jardine's will clean up REALLY nice, very happy about that.

I think I have a lock on some wheels with used tires.  Stock sizes, off a '76 with four year old RoadRunners on them.  He wants about $200 for the pair, but hopefully he'll take a little less 

[service-guy]

I have a Ignition Switch off a 1976 Super Sport, with keys, if your interested PM me don't need it, it will go cheap.

Thanks, I just bought a $6 key with the code off the switch I've got.  Should be enough to get her started.  Might be buying a spare motor tomorrow too.

[Greggo]

Some parts showed up today 

[Greggo]

Thought I'd update this one a little.  Went parts shopping at Charlie's after work.  The bike is up at my dad's shop, waiting for me to get a couple days off.  Thorough carburetor cleaning is at the top of the list, then wire connector clean up.  We got a battery, and were able to get the lights to work.  No signals on it just yet.  A HondaMan transistorized ignition will be on the way next week.  I had to return the single point unit for my CA95 because we weren't able to ground it to the point plate.  So, Mark has been kind enough to let me return that unit with a few extra dollars, and get the dual point unit for the 750.  Thank You HondaMan!

Bought today:

Throttle Sleeve
Tank Rubber
Master Cylinder Rebuild Kit
Ignition Switch
Galindo Grips
Handlebars
Air Filter
Clutch Cable

$152 after cash discount (no tax: saved $13 bucks)


Member Tomz is trading my velocity stacks for his stock air box.  He's building a nice chopper.  I have a really nice 17x2.5" rear wheel I bought on fleabay for $45!!

[Greggo]

Had some progress on this bike.  Chopped off the molex connector end of the starter switch Domer gave me with the bike and installed bullet connectors on all the wires.  One of the colors didn't match, so we compared color diagrams and sorted that.  I have two bad coils.  One was firing, but not the other, so we swapped coil wires, and the problem followed, then the second coil crapped out -- Both are getting power from the points, and are grounded, but not firing. 

My K7-K8 rear wheel showed up and it is NICE!  Ebay SCORE for $45.  It's a 17x2.5" Anybody know if this wheel will fit right onto my K6 without spacer issues?  I have to swap the cush drive into the new wheel too, hopefully that's not a problem.

It's a slow week in the shop, so my dad and his shop partner Ron (both ind. VW mechanics working together for 35 years) were both helping me.  My dad mumbled to Ron as he was trouble shooting the electronics, "it's a volkswagen" - Made me smile. 

I started with this jumble.


And this was the molex connector I chopped off.

[Greggo]

Ordered some new brake lines from Shaun (SlingshotCycle) It's a really good deal with the SOHC4 discount.

beware of that emgo ignition switch. Do a search here for the problems others have had with them. Something about they aren't made to handle the amps of the 750.

Oh, I know.  It was a cheapy temporary fix just to get the bike running, and sort the electronics.  Problem is that OEM switches are $100+  I may just go the HondaMan ignition switch relay route, and stay with the Emgo.

On a side note, my HondaMan transistorized ignition unit is rolling down the assembly line at HondaMan Headquarters as I type!

[Greggo]

I've been following your K6 Hoodelly, that's a nice bike you found!!

[joe29]

Good stuff Greggo  .... following along.

[Greggo]

Hey Joe, wasn't it you that saved this bike from the street in the Mission, and gave it to Danny?


I've been running a CL ad looking for a spare motor to build up for later, and I got a response yesterday...from Grumpy!  He was one of the riders we met up with for the Rally in Santa Cruz!  I think he figured out who I was with my email, and the bikes I told him I have.  So, looks like I've found my spare motor once his replacement engine is ready.

[joe29]

Hey Joe, wasn't it you that saved this bike from the street in the Mission, and gave it to Danny?

Nah, different Joe.  I wish it was me that found the bike though. 

I just picked up a couple spare 750 motors last weekend too.  I bought one of those cheap 836cc kits on ebay to play around with.

I was looking at those for the engine I'll pick up from Grumpy.  I hear they're made in Japan, so that's a plus.  Can't beat that price.

Switches are not made to handle amps. Relays handle the amps.
That is why you have a horn relay.
That is why you have a starter relay(solenoid).
That is why you have fuel pump relays.
See what I mean?

Here's a quote from Mark's (HondaMan) website on the EMGO switches.  He sells a relay kit for just this.

"The problem: the EMGO switches that are now widespread contain 8 amp contacts inside, which get hot in operation on the vintage Honda Fours, particularly on the CB750K0-K4 and CB550 models that have the keyswitch mounted on the frame (i.e., not in the instrument cluster). The OEM contacts in the OEM switches were rated for 16 amps and included large (Red and Black) supply wires, which the EMGO switches lack. The failure mode of the lesser switch is usually a Red or Black wire melted off the back of the switch.

This Relay Kit removes the heavy load from the keyswitch, letting a relay do the hard work."

Brake lines from Shaun are in the mail! Stoked!
