Honda cb750 sohc clutch talk
The quest for the perfect "higher performance" Honda cb750 engine continues.

With a lot of high-performance products offered for the Honda cb750 and nearly twice the power ..... the clutch can be a problem.

Photo #1:
Here is another version of the clever 6 spring clutch package.
Details:
6 springs for multiple pressure options.
10 Kevlar friction plates. (Stock Hondas have 7 friction
plates)
OEM steels with one double steel.
Lightened outer basket.
Modified inner clutch hub.
Frictions are steel based with Kevlar material. (No alloy expansion for keeping stable adjustments)
Nylon inner clutch sheath with nylon impregnated wire cable. (amazingly smooth)

No chatter.
No slipping.
No lurching forward or dragging.
Smooth, predictable feel.
Race proven.

2nd photo:
We acquired this top fuel rolling chassis a while ago and didn't know much about it except for noticing the high-level workmanship.
We received a phone call asking us if we had any questions about it ...... because he built the rolling chassis.
Turns out the builder was the main fabricator at Kosman drag bike enterprises.
Remember "Sandy" Kosman products?
He had some great stories about the olden days.

Hello Honda cb750 fanatics, enthusiasts, fans and owners.

Here is a trip down our memory lane to the present.

1st photo:
30 plus years ago we were wanting and needing a carburetor upgrade versus the offerings years ago.
We discovered that 84-86 Kawasaki RS 34 mm Mikuni carburetors were spaced pretty close to Honda spacing.
Theoretically speaking ..... the 34mm carbs were going to be too big for the cb750 engine ..... but we pushed and pulled them into Honda intake manifolds and the rest is kinda history.
The Mikuni's are now respaced even to closer spacing and regularly used on Honda cb750 models.

2nd photo:
30 plus years later with painstaking effort, research and investment the CycleX Honda cb750 cam chain tensioner had a large part curing the OEM tensioner problems plaguing the performance Hondas.

3rd, 4th and 5th photos:
Here is another AHRMA road race engine prepped for the 2027 season ...... you should make plans to see a full grid of high-level Honda race bikes.
2027 schedule coming soon.

6th photos:
Very nice Nova transmission installed in our cut-a-way case to check things ...... just to be sure.

Video:
Many engine builders are amazed at the videos of our crankshafts freely spinning after our case and crankshaft procedures.
Me too.

Building a Honda cb750 sohc engine strong first ....... then fast.
Nothing really secretive about these lower end parts or procedures in the photos ....... the top end will be somewhat classified for now.

No real need to have pretty painted or polished parts on a "full mod" race engine.
Fun fact:
Many racers didn't use case sealer because they knew that engine disassembly was inevitable at some point.
We are very confident in our parts and procedures that we used a thin coat of Honda bond ...... also, to avoid a small oil leak and disqualfication.

Lower end list:
18.5 lb crankshaft (stock crankshaft averages 21.5)
Treated to all the numerous CycleX crankshaft upgrades.
Case crankshaft areas are "line lapped" for straightness and roundness ..... then measured and fitted with coated bearings to exact clearances.
Carillo connecting rods are fitted with coated bearings to exact clearances.
Multiple breather modifications.
Late model transmission with 2 degree undercuts and up-down undercuts. 5th gear mod also.
Chain wheel and clutch components are refurbished, small changes, lightened a bit and balanced.
Modern high-level primary chains and slipper tensioners are installed ..... upper and lower areas.
Shift drum mechanism modifications are installed. (wheel and detent spring)
Oil pump with an 8% stronger pressure releif spring.
Deeper finned oil sump pan.

Just a small progress report on some engine work.

It's with-in tolerance is a phrase not used around here.

Accuracy, precise measuring, proven upgrades and persistence would be needed to build a "better than new" 50-year-old race engine.

Photo #1:
The crankshaft, connecting rods and engine case area always have our full attention.
Here is some final checking/measuring and cleaning of a full mod Honda cb750 sohc lower end.

Video:
Coated main bearings with precise clearances allow us to briefly spin the crankshaft as a final test.
Looking for irregular main bearing "witness marks" and verifying end play are the goals.

Last photo:
Yes.
Better than new and ready for assembly.

Hello Honda cb750 devoted fans.

Checking, cleaning, machining, testing random full mod engine parts.

Photo #1 and #2:
Always liked looking at parts in real life after some machine work is done ..... so here are some engine cut-a-ways to evaluate the final products from time to time.
Primary chain tensioners for chain control are being assembled in the photo. (upper and lower)

Photo #3:
Crankshaft and rod bearing fitments complete ..... perfect.

Lightened.
Carrillos.
Coated bearings.
Oil holes enlarged and relieved. 020 deep main bearing oil groove machined.
Micro polished.
Blind hole oil passageways cleaned.
Balanced to perfection.
Rod bolt stretch/ torque verified.
Final assembly coming soon.

Photo #4 and #5.

Nearly ready for lower end assembly ..... almost.
More breather mods on a different engine.

Thanks for looking.

Different random activities in the shop this week.

1st photo:
Accurate Honda cb750 racing crankshaft work for the AHRMA racers.
Actually, the same procedures for a stock build.

2nd photo:
We liked the alloy sleeve and plated cylinder upgrade so much ...... we decided to make 64mm (811cc) piston and cylinder combos for the perfect mid-size Honda cb750 engine..

3rd photo:
Not exactly breaking news ........ a batch of remote idle cables are back in stock.
No more bending over to adjust your idle and to help idle-up during warmups.

Cables completed for:
Honda round tops.
Mikuni RS carburetors.
Keihin CR carburetors.

18 years ago.

1st two photos:
We offered rolling chassis kit bikes with the idea of installing your own engine.
The idea never really worked out ...... but we tried.

Next 4 photos:
Early, early photos of the shop ....... cool memories and humble beginnings.

Just a few Honda cb750 custom bikes being built years ago.

Bad:
Generally, no ground clearance.
Handle terribly.
Zero suspension.
Looks are a matter of opinon.

Good:
Generally, good power.
Personalized.
Known to pick-up a person's social life.

Looking back a few years.Here are some of my favorite Facebook photos ..... so many photos to choose from.
