1978K for Resto Mod

rich
I'm trying to catch up with Tools. I added two more to my stable today.

Bought this '78K today. It's relatively unmolested. It has a four-into-one header but other than that stock. 26K miles. Runs pretty good, no smoke, no strange noises. Little bit of a bog off idle - accelerator pump?



The owner had a king and queen seat on it. However, he still had the original and it was in good shape.





This followed me home too! It's a 1989 Kawasaki VN750. It has some road rash on the left muffler and small dent in the tank. Again, all stock, around 26K miles.

Guy made me a deal I couldn't resist. For what a good running complete pre '79 CB750 goes for around here, I figure I got the Vulcan for free (that's my way of justifying it). I'll tinker with it and clean it up and see if it'll sell for enough to cover the cost of both. Already found a good muffler for it on ebay along with a couple of other bits it needs.


I passed on the Vetter though. LOL

That CB is a year too new for you. Better let me take it off your hands. Those Vulcans are pretty popular bikes, you should not have any trouble selling it.

Maybe I should collect one CB750 from each year of the 70s instead of every 1977 model they made.

Re: 1978K for Resto Mod

I got the bikes home last night and unloaded them today. I noticed the chain was way too tight on the CB750.  As I got ready to adjust it, I also noticed the MASTER LINK CLIP WAS MISSING!

So I want to order a new chain and sprockets, and convert to a 530 setup with an o-ring chain. I started searching for recommendations and noticed that 78's came with a 17 inch rear wheel. Mine's 18? I guess it got swapped somewhere along the line.

When shopping for sprockets what should I be looking for? Or how can I tell what's on there now (77/78 parts or older parts?).

I always ran 18-48 sprockets. Gives you about 6k rpm at 65 mph. You are used to the power of a DOHC. In comparison the SOHC will be fairly evenly matched regarding upper rpm power,but the SOHC's do not have the bottom end power of the twin cams. IMO, they need to be geared to rip.

I use steel sprockets because they are cheap( about a dollar per tooth),these bikes aren't light and I like to play hard in the mountains. Anything under a 9500-10,000 psi tensile strength chain tends to stretch real fast for me, so that's what I use. My last three chains came from BikeMaster. IIRC, they are rated at 9,600 psi tensile strength. 530 with o-rings. They usually run about $60-70 depending on length. At that tensile strength from BikeMaster they come with a rivet-on master. I spend another $5 and get a clip style master for them.

The garage is getting filled with boxes from ebay with all the stuff I keep ordering. My checkbook register has about two pages of payments to "PayPal". This is just some of the stuff I ordered for the Honda.

Owners Manual
Got the tool kit so I may as well have the owner's manual too.

Grab Rail
I only needed the grab rail but the fenders will come in handy (given my record for having women wreck my bikes with hammers and cars).

Orings
The tappet covers were weeping a bit of oil.

Side cover 
Both side covers are held on with wire.


Oil Filters
Got a half dozen oil filters. They also fit my 79 750 and Goldwing.

plugs
I got Iridium plugs. Love them on my 79.  

breakleaver
The tip of the break leaver was busted.

chain
I just got this cheap o-ring chain for now. Still going to run with the 630 sprockets as they look pretty good. I'll convert it to 530 next year.

Fuel Filter
The 90 degree filters can be hard to find at the local hardware stores.

Points
Points. Now, where the hell is my dwell meter? I haven't used in years.

Manual
A hard copy manual is nice to have.

Exhaust
My 4-into-1 has to be removed to get to the oil filter so I got new gaskets. I'm not sure I'll keep the pipe. But for this first oil change, I'll take it off and paint it with some BBQ paint and see how it holds up.

Schocks
My shocks were leaking. These looked cool. They will go nice with the gold chain. LOL.

Re: 1978K for Resto Mod

I installed the same Iridium plugs in my '79.  It started instantly, the first time I hit the switch -- I literally jumped, as I was accustomed to it grinding for 4-7 seconds before it fired (original coils and wires).  I installed Progressive brand shocks, no external oil reservoir like yours have -- rode like a modern bike afterwards (I installed the Progressive Fork Springs, same time).  Those progressively wound springs, on the shocks, are like having two differently rated shocks on board, all the time -- you will love the new suspension.  I also installed a K&N air filter:  the butt dyno approved of the 'performance increase'.  Adding some new bits to my old bike really changed it -- talk about breathing life into an old motorcycle!  Looking forward to reading your comments on the ride after you finish the upgrades.  Cheers!

Re: 1978K for Resto Mod

I'm wondering if I need to gap the Iridium plugs to the 78 750 spec. On the 79, with electronic ignition, I just left the gap alone because I read you shouldn't mess with the sensitive tips on the Iridium plugs. But the old points-type ignition on the SOHC doesn't seem like it would be able to deal with the wider gap.

Re: 1978K for Resto Mod

So not to happy with the gas charged shocks. They're too long. The ad said they were 13.2 inches. Well that must be without the clevis mounted. Overall they're 14 5/8 inches. I put them on just to see what it would like like, I was thinking maybe a scrambler/street tracker set up with low bars and bobbed fenders. But the gap between the back tire and fender is huge and a bigger tire will just jack the ass end up even more.

Shocks mounted

To add to the disappointment, I broke the threaded portion of the shock mount off. The nut went on OK but busted the mount when I tried to get it off. Bummer, but Tools said he could help me fix it up.

This is the mess I made when I tried to drill a hole in the mount to run a bolt through it.
No drilling 

In other news, the Vulcan is looking much better. I replaced all the parts from the previous owner's crash. He went down on the left side. I replaced the front and rear turn signals, the headlight trim ring, the clutch lever, the muffler, the shifter oil seal and the side cover. Got all the parts from ebay for around $200-$250. I also installed Iridium plugs, new air filters and changed the oil and filter.  I put my sport bike soft bags on for now, just to have some storage. Looking for a cheap set of leather bags. I think they'll look a lot better.
Vulcan Left

Vulcan right

I also installed a manual cam chain tensioner on the front cylinder. I got one for the rear but I have to modify the coolant overflow bottle to install it. The front chain was making all kind of noise. The stock tensioners aren't serviceable and fail quickly. The manual tensioner quieted the chain noise down nicely. It's butt ugly though

No hard tails. Too many dirt roads around here. Maybe you can move the lower shock mounts to make it sit lower.

Why not convert the Honda to electronic ignition?  I find it works a treat and it's a fairly easy mod to do in a couple of hours.
