Interesting build HB. I rescued a 78 750 from my neighbors shed a few years ago in order to revive with my step son. He moved to Austin so I sold it to my pals Mike and Mario at Standard Cycle in Berkely Heights, nj. I think you can see it on their website. Pretty cool and almost done as it has been for a couple of years now! Another fellow up there does the treatment on unloved Hodas and then sells them. Nice and low budget. Check them out!
As for me. Getting ready to rebuild the Hornet motor. Sure would like to regain the record. Won't be easy. PRT

Tom, the weather/wind is always a factor at Maine...I seriously doubt my 650 Triumph will be there again..We are going to concentrate on the dual Triumph engine lump......When I bought the Honda a ride taught me what I suspected, decent but dumb slow handling bike....Honda used offset yokes on the 750C to get near 30 degrees rake....Now with the 96 Interceptor front end I set up the geometry at ride height for 26 degrees rake and 4.2 inches of trail with a 120/70-17 front tire...this should sharpen the handling without being too twitchy..

Yeah, The wind. I always prep the bike for best situation and then pray. Sometimes it all comes together up there. Not so much in Ohio! In '16 we caught the breeze and the bike ran very well. '17 your bike ran very well. Mine expired. Ah well, we have to be extreme optimists to do this stuff. Will look forward to seeing the double next year! PRT

the wind and the temperature at loring drove me nuts. at the beginning of the day i'd be out on the line, suited up, warmed up, and ready, RAD 105, 3 mph tail wind, and the track people would call a rider's meeting, or a congratulation meeting for the people breaking 200 mph.

i loved the low-key atmosphere, but not while the temperature was going up and the wind was going down!


i have no idea what i'm doing.

What the bike looks like today....I painted the parts and while the engine was out the side covers were removed so my wife could polish them. Also polished the fork sliders...With the engine on the bench the head and cylinder were pulled for gasket replacement... I honed the cylinders, new OEM rings and new valve guide seals just because it's 36 years old...Lots of parts inside one of these lumps....

Interesting thread.

I was once a Honda dealership mechanic. Your comment on the fit & finish of the engine cases got me laughing. I never cut my hands as many times in a single week as working on Hondas all day ! I had to start keeping Band-aides in my tool box it got so bad. The Red Cross would come around and I'd have to tell them "Sorry, I gave at the shop." All that bleeding was a major impetus for me to start back in college.

The front ends after 1975 were pretty good, but it's the rear end you need to pay attention to. The swing arm may need stiffening, or even an after-market version. Definitely install metallic swing arm bushings. And the OEM rear shocks gotta go. And of course, you gotta go with stainless steel braided brake hoses everywhere.

Look forward to seeing the finished product.

PS. Just spoke to a pal this weekend who'll be selling his Honda 400/4, Honda 305 Super Hawk, and late model Honda 500 twin (not sure what model). These are all stock condition. And my brother is still sitting on his stock CB750 F1 he bought new. Any takers out there ?

Yes, sharp edges on the machined gasket surfaces...I believe it grips the gasket better ? This 81 750 is the first year for the needle bearing swing arm pivot...The stock swing arm is 1.6 inch OD oval tubing with gussets at the pivot tube. the axle mounting plates are about 3/8 thick steel, the whole affair looks quite sturdy, it surprised me so Honda learned a little about frames as time went on....I'll buy new shocks after initial rides to see if they need to be longer or shorter to adjust the steering geometry...Right now the bike is set up for 26 degrees rake and 4.2 inches trail with a 120/17 front tire......

No, the Japs just skip the step where they remove the casting flash altogether. If you'll look at a European motor, you'll see plenty of evidence of someone with a die grinder working on each casting to remove flash and de-burr drilled holes. Example... the tips of the cylinder head fins will be finished off. Not necessarily polished, but not sharp castings either.

The Jap stuff is simply cast, machined, and then installed.

I do know my 96 Ducati 900M has very intricate engine castings with lots of webs, good machine work and many screws to hold it together...While the inside looks impressive, the outside of Ducati air cooled belt drive engines are quite rough like an old Triumph...I guess that why Ducati painted the engine exterior...The Honda was also painted but most has worn off...
I noticed the Honda transmission has pressure fed lubrication...

New exhaust, I see .... What kind is it? I ask because I've learned the importance over the years (as I know you have) of matching the exhaust to the characteristics of the flow from the engine .... intake, displacement, exhaust, port size ... so that exhaust pulses help each other out and don't get tangled up ....

I stopped believing for a little while this morning. Journey is really going to be upset.

The exhaust header is used and of unknown make ....I made the long 2 inch collector before the muffler to increase ,in theory, the midrange power. I also bought a Dynojet kit to fatten up the mixture for no air box and less restrictive exhaust...The engine is stock internals...

Looking Good!!!! Dyno-jet stage 3 you get you real close with pods. I have a 80 GS-850 & 78 GS-750 Both with pods, 4-1 exh. & Dyno jet kits. The 850 with CV's a little easier to tune.

Heated lockup HB?

1979 onwards Hondas could go round corners, CB900F was big step forwards for Honda. In the UK it was possible to buy a CBX1000 or CB900F or a Gold Wing. CBX engine is still impressive a mere 40 years later.

Heated lockup... That's the basement of my house, 1200 square foot of work area, the double white doors open at grade level...... This bike has needle bearings for the swingarm pivot, I believe 1981 was the first year for that ... The frame geometry is now set up at ride height with 26 degrees for rake and 4.2 inches of trail.

71 T120 rear fender....License plate mounts under the right side tail light...

heat would be nice. i put stuff off because it's too cold to work.

i have a huge workspace with room for anything. insulated pretty well but floor heat not hooked up.

dim, too. this weekend i'm going to go purchase five more 8-foot double fluorescent fixtures and conduit to brighten it up.


i have no idea what i'm doing.

Nowt wrong with living over your lock-up, I looked at buying a disused fire station a few years ago, complete with powered folding doors to the street and living facilities on the floor above (UK 1st floor). That would have been a magnificent lock-up.

1979 Honda 900, perhaps Europe only(?):

The other property we owned had a house, and a heated 900 square foot shop out building....We moved here last summer.. It's an 1860's house that was redone about 30 years ago with a large basement...I can ride bikes in or out through the door ,around the house and onto the road..It's nice but has one disadvantage, If I burn down the shop, the house burns and we'll be living outdoors with the chickens......
I installed the carburetors and hand grips last night....The bike is ready to start.I need to make room soon for the double engine Triumph race bike maintenance....But it snowed a foot overnight so .....................

Found a 90's Sportster solo seat....I started it several times yesterday...No smoke or leaks..The exhaust has a nice mellow sound and not the raspy howl like many inline 4's or the tin can sound of stock mufflers.A new class of bikes..Cafe Cruiser
