What a concept - A Girl Bringing Back Her 1966 Super Hawk

Sarals,

30 tooth is standard for CB77. 530 chain X 94 links.

My Hawk has a 33T rear sprocket fitted. It's worn, and I should replace it. The question: what was the "standard" tooth count on the CB77 rear sprocket?

Exhaust - will the the Dunstall (Emgo) 27 inch replica mufflers be acceptable, and do they bolt up properly?

Tires? I know about the Avon 80/80 and 80/90 18's - how about the Heidenau 2.75x18 and 3.00x18 (on eBay)?

The main drive chain - it's a 530, I know that, but what is the length - is it a 102?

Yeup - more than one question!

The Heidenau tires should be fine - I have them on my bike, though I opted for a slightly larger one on the back (3.25)....just a personal preference. They're good for general riding, and seem to perform pretty well on the twisty backroads, though I haven't tried them in the rain. Oh and they do look good on the bike -- very important!

As far as the EMGO Dunstalls go, I've had at least two sets on my bike over the years. They hang a tad lower than the standard mufflers, so you may touch the ground a little sooner in the tighter curves (but nothing really to worry about). The thing that I found was the Achilles' Heel on them was the rear mounting channel on the backside of the mufflers -- likely due to vibration, the 'facing' plate of the channel has a tendency to fracture. If you aren't planning to ride the bike more than the occasional Sunday morning etc, it's likely nothing to worry about. But if you're going to be using the bike for extended road trips or using it more frequently, I'd be aware of that possibility. Maybe I just had bad luck, or maybe my bike vibrated more than others at the time, but it happened on three different EMGO mufflers that I had, and eventually I switched to the Norman Hyde TOGA mufflers that are now on my bike, and have never had a problem with them. Of course, they were about $500 a pair, vs $100 a pair for the EMGO, so don't know if price/quality make a difference. The finish on the EMGO mufflers is pretty decent, the welds are neat, and I don't think you'll have to worry too much about rejetting.

Vince, thank you! That's great information, every bit of it.

I will probably go with the Heidenau tires. I agree that they do look good!

I'm searching for a right side muffler, a stock one, for my Hawk. I'd like to find one of those in lieu of an aftermarket exhaust system. My left side muffler is solid. It is scratched, of course, but it has only some surface rust and no serious dents. It will polish out very well, I think. I would be very happy to find a right side muffler in similar condition. As I said, I'm not looking to make my old girl into a "contest winner", just a decent looking daily rider. Because I intend to ride her, and not just occasionally, it seems I'd be better off holding out for a stock muffler. Wish me luck - they seem quite rare!

An update:

I've been acquiring parts for the Old Girl, as well as doing some work stripping down the frame. I've purchased many needed parts from some of the kind folks on this forum, as well as some of the great on line sources. My local Honda dealership sold me a new 530 chain, and a wrong sized screw that was supposed to be a 6 x 8 mm (they apparently can't use a sizing chart). I've bought a correct, whole front fender; a seal kit, cam chain, electronic ignition, battery, intake air tubes, cables, headlight trim ring, rear sprocket, and a header pipe. I've also picked up some supplies, Hondabond 4, steel wool, polish, paint, primer, degreaser, white grease...etc. I will buy tires, soon. I need to find either a right side muffler OR an aftermarket (Dunstall reverse cone style) exhaust system. I need to find another header pipe, too.

I'm moving forward, and this is exciting!

The parts are beginning to arrive. The anticipation is growing! A new 30T rear sprocket from Classic Honda, new chrome acorn nuts, new rubber bits, new screws and fasteners, new O rings, new seals, a new header from a friend here on the board, a new chain, battery...on and on. Oh, she's going to be nice!

I spent some time today doing preparation and cleaning. I degreased many parts, giving me opportunity to start assembling some components as well as prepping other parts for paint. I degreased the frame, the swingarm, the right side engine case cover, the starter, and the magneto. After that I disassembled the magneto and carefully cleaned the coils, the wiring, and the inside of the mag's housing. I then carefully put it back together (let's not pinch those wires, okay?). I started sanding the swingarm and did some more sanding on the frame. That is going VERY slowly, so I may use the aircraft paint stripper I bought on the parts of the frame I want to respray, as well as on the swingarm, headlight bucket, and gas tank. I'll try a small item first, to see how the stripper behaves, then go from there.

Starting tomorrow I have seven consecutive days of work. Drat! I'll get back to the Old Girl late next week.
