Topic: LostSoul's Project "Lucky 13" build

[754]

Just looked at this for first time..
 I think you should have kept the wheels/ fork..
 You had something unique, but now switched to what a lot of others have..
 Why would we hate you, you are not the only one on here that gets great deals. Some of us have done wwwaaayyyyyyyyyyy better than that..
 All 750 Honda heads are sandcast, too hard to diecast..looks like a late head..
 Maybe call it a cafe, cuz I am not seeing any pro-street looking at that bike..
 peek in the sparplug hole, tell us what you see..

Thanks for clearing that up with the head.  I would have thought they would have at least cleaned up the casting marks on the later models, but then it's not really efficient for them to do so, makes sense.

Honestly, the only thing that was unique was the wheel setup.  I can take pics of everything that was cobbled up together from what seemed like a rush job, but I'm going to take my time and fix things as well as upgrade as I go along, plus I hate pointing out mistakes because I know I do them as well.  It may not look the part right now, but I'm nowhere close to being where I would even think I'm halfway done.  I value your opinion though.

So it's been a little while since I posted up in here because I decided to just do what I felt should be done to my bike and got busy doing, so here's some up to date things.... 

Finished fitting my HID headlight and test fitted with some LED markers on the sides...


Got most of my wiring sorted with some tests that I was getting power through everything and used an R1 tail light I had (motor cranks over with my new CBR start switch also    )





Then I got busy with the rear part of my frame.  Cut off the rear upper loop thingy, cleaned it all up nice....


So then I fab'd up a pan for all the electronics to fit... (stator, TS relay, start solenoid, wires, etc...)


...got to tacking it on to fit it a little better after removing all the wiring so nothing was scorched in the process....


Then I finished stitching it on (not finished as of yet, I need to touch up a lot of places to make nice and smooth, but shot it with some paint so the welds didn't rust)....


So besides having half of my wiring harness heat shrinked and sorted, this is where it currently sits.  As for the engine and bore size, I do not know yet, but after looking in the spark plug hole, there are some nice valve reliefs.

Looking good man. 

[lucky]

You did not just get a deal,you got the bike for free really. Just the exhaust is worth over $500.

Its who you know.

[LostSoul86]

Looking good man. 

Yours is looking good too Kevin, keep on doing what you're doing!

Agreed, I saw the bike as a blank canvas when I first looked at it and kept an open mind about it.  As I tore into it, I kept finding more and more about it that I liked and went from there.  I wanted something with soul, and this bike really fit the bill and I haven't looked back since.

[hapakev]

Thanks man, I appreciate that.

[70CB750]

Looking good, like that tail light.

[LostSoul86]

Time for an update....

First and foremost, new helmet    Icon's "Lucky Lid"



My progress includes, getting the headlight mounted....


Working on tail light and tag mount ideas (final version pieces coming in soon)  I asked a FL State Trooper regarding lighting and tag location, this is legal in my state.


Got my tank in from Hapakev (big thanks Kevin!!)


It lasted like the above for a day....


and today, I got busy on making my rear tail piece/electronics cover....



and finished with...


So there I am with my progress in case anyone was wondering 

[hapakev]

Nice, looking very good man.

You will notice that this 1978 CB750 has the 1969 carbs.
 Someone made a very smart move.

I would really like to know what the jetting is on those carbs. LUCKY

Can you PM if you find out??  Needle clip position too.

[lucky]

if the motor is a 78 f it has really early k carbs on it.

There is a VERY GOOD reason those 1969 K carbs are on there.
You are very LUCKY!!

I would really appreciate if you could tell me the jetting and needle clip position on those carbs!!! THANKS LUCKY. Please PM me?

[lucky]

interested to see how the turbo wheels were adapted.
not looking to sell that are you?

Low on a CB will not handle well.
actually you want 1 inch longer rear shocks to make the bike handle.


Are the carbs marked with a "28" on them?
might be worth some $ to a rest guy.

As a matter of fact, yes, I might be looking to sell the setup, ready for bolt on.

I was going to raise the rear a bit, it actually has some reverse rake to it which needs to be addressed.

Depending on what comes off, I might just sell them and go for either the Cycle X dual Mikuni's or swap on a stock set from an '87-'88 F model. Still looking for a number, but I haven't looked over the entirety of the carbs yet.

You meant 77-78 model not 87-78 
Also getting rid of those carbs would be a big mistake O'Grande!!

You won't have trouble sell them but boy will you be sorry!
Why do you think they are almost impossible to get?

Those 1969 carbs were the easiest to work on of all the CB750 carbs.
The float bowls pop right off for jet changes.
Those 1969 carbs are VERY tunable.
The idle jet is the screw in type. The 77-78 were not.
The slide needles can be easily adjusted if necessary WITHOUT even taking the carbs of of the bike.
All adjustments were very easy to get to, unlike the 1977-78 mixture screws which were a bit@# to get to on two middle carbs.
The stock 78 carbs had non adjustable needles.
The stock 78 air box had only 3.7 sq. inches of intake area.

Do you still have the cx500 wheels? I'll buy them off you as long as you include all the parts to run them on a cb750...,

[lucky]

Whats going on with that now???

[lucky]

Gone ?

[Rigid]

I recall this was comstar 400 wheels and a cb550.  Swap required little drama as I recall.  Maybe a spacer on the front?

[Geeto67]

the problem with comstar wheels, is they are all 5 lug bolt patterns where as the SOHC wire wheel is a 6 lug bolt pattern. Why is that important? the brake rotor. The comstar has a different rotor spacing, rotor thickness, and rotor diameter. Even if you can find a 5 lug rotor that is the same spacing and diameter, the thickness still makes it an issue as clamping force is severly reduced.

There are many styles of comstar wheels:
- standard comstars (1979-1980). available in a variety of sizes (16"-18" rear to 19" front) and brake configurations (drum rear, single or dual disc front). Steel wheel spokes riveted to alloy rims - tend to corrode around the rivets leading to failure (not common unless stored in water or humid climates).

- Reverse comstars (1981-1984) concave wheel spokes rather than convex. Otherwise same as standard comstars. Some of them have aluminum centers

- Boomerang comstars (1982-85) Three spoke split wheel similar to a PM chicane wheel. Available in the US on the CX500 Turbo only, but in the rest of the world on the CB750F integra and the cb1100F in various anodized finishes. Fronts are 18" and interchangible with any other comstar wheel. Rear for the chain bikes is 18". As far as I know the cx500 turbo rear wheel is spline only for the shaft drive and cannot be interchanged unless with another shaft drive comstar. Some have speed holes and some have slats down the spoke depending on the model of bike.

- 6 point comstar (1984-86): used on the VF1000R. 16" front, 18" rear.

- three spoke comstar (): tiny bike comstar most often found on the MB5 and other small bike (50cc) products.
