It just threads on where the OEM filter housing's through-bolt goes.  For the Randakk adapters you're meant to use a wrench with 2 pins on it to install/remove it.  Something like this - https://www.amazon.com/Grinder-Universal-Adjustable-Wrench-Machine/dp/B07MFY3HNY/

If you have a drill press you can create a small pin wrench drilling (and tapping holes if you want to not use a nut) in the jaws of a adjustable wrench...
Just need to choose a screw or make a pin to screw into the jaws that is strong enough to not bend (Stainless is going to be softer than a grade 8 machine screw or 10.8 if tapped in metric...

I had two different Harleys. Both lost a belt due to.a rock. I lived on a dirt road at the time. I definitely did not have the right tool for the job, LOL. Ask me how I feel about belts, hahaha

I’ll bet +50% of the cb’s I’ve worked on were missing the washer and often the spring too!

I like the stock filter set up. When pulled you just have to open up the pleats in filter to see the condition of the engine and trans. By design, the few extra fins theoretically add some extra oil cooling as well.

All spin on filters, I have had in my hands were extremely thin skinned. A thing to weigh in your decision: not only terrain but also roads have sharp gravel here and there and if that on impact can break a windscreen, it can also damage a thin skinned device that's only inches above the road. The OEM filter is robustly housed.

Yes. I rebuilt a 750 with spun crank & rod bearings about 8 or 9 years ago. When I emailed the owner to ask him for his oil filter housing (so I didn't have to source a new one, and all the pieces) he said it was previously a spin-on Motorcraft oil filter - with a small hole in the bottom, in a large dent. He said the PO had mentioned riding it on a dirt road and then hitting the interstate before the oil light came on: he "only rode it to the next offramp" after that, but the bike stopped when he slowed down. It went home in someone's rented U-Haul trailer afterward. Then he sold it to the guy who sent me the engine for rebuild.

Can be different depending on where you live.
Gravel/small stones can hit engine without driving in the outback.
When they restore roads.
An asphalt grinder has grinded off a layer of asphalt before a new layer.

Small stones can be left, follow the wheel and hit the engine.
They are often a little bit sticky.

I prefer the original robust filter housing.
My car has a spin on filter, but it sit covered by a  cover under the entire front direct followed by another cover under the gearbox.

Debris on the road another thing. Small metal parts like the one that caused the end of Concorde when it crashed in France.

My cars have hit such things I had to inspect to not hit a brake or fuel line. Fill the scratch with primer and bitumen as rust protection.

I have also ridden in Europe. From Sweden to former Jugoslavia, Italy and Spain. Over Denmark, Germany, Austria, France and Andorra.

Debris on the road is rather common after a recent crash. Autobahn crashes were often a huge debris field.

Roads in the Alps and Pyrenees are not always that good. Farmers tractors spread dirt with stones as they do here each spring and fall plus cars spreading the gravel outside the asphalt in curvy parts of the roads onto the roads.

I should never replace stock well function oil filter setup.
Different if bike should be a show bike never ridden on roads.

Forgot to mention that small stones are rather often stuck between the cooling flanges on the stock filter cover.
Very seldom rides on pure gravel roads.

Often you can find longer spin on filters which contain more filter area. Having more filter area means less chance of going into bypass. A longer filter with more filter area will last longer. That being said the stock filter works fine and it does have cooling fins, for what that is worth.

Just curious since you mentioned “bypass”….

What happens to Honda’s bolts bypass when using the spin on conversion…?

What is the spin on filters bypass pressure differential…?  Or do you know..?

  Since they’re application specifiic I would want to be sure I wasn’t getting a higher bypass pressure than stock or something designed for a 10 gallon per minute high volume oil pump…

[Deltarider]

I've ridden a ton of gravel roads on my Suzuki GSX-S1000 and never had any issues.  Never even had a dent on the oil filter and it's right behind the front wheel.

Oldgreybeast, with all due respect, I'm more than familiar with your type of reaction. In the past I've warned unnumerable times for the risk of running inline fuel filters on a CB500/550 and I have shared my personal experience with them. More than once a person thought it necessary to reply: "O, but I have ran them for years without a problem." Such a reaction is trivial, anecdotal at best and has little value against a serious warning.
BTW, in this thread you will find evidence that a spin on filter can indeed lead to trouble. True, that post is also anecdotal, so a reader has to weigh its value against your post.
It is my wish that in this forum there were less reactions like yours, where others know better from experience. The latter posts have a warning where yours is trivial.

Bosch 3323 bypass at 14-18. Which is the filter I read recommend by a member here.

[rotortiller]

There are spin filter brands out there with thicker casings. I have seen stock CB oil filter housings cracked from serious road debris as they do not dent like metal to absorb the impact. I would use either  and if you do go off road try a mud flap on the front fender lol. Mobil-1 filter casings are thicker than others.

I just came across that info as well in my research.

So if we were to use the Bosch as an example, it would open the byass 3-7 lbs earlier than the stock filter setup.

I am new to this sort of thing, would that mean a detrimental effect?

That’s the Right question…😁

[Tracksnblades1]

It’s your nickel..or dime..

Your next questions should be.. I wonder why Honda speced  it that way..?
I wonder if Honda saw it bypassing on cool mornings with throttle blips….?
Especially with higher than recommended oil viscosities…?

Or, Should I go with what the member anecdotally recommended without the extensive testing and research Honda expended…? 🤔

I just sent an enquiry into Wix to see their recommendation for spin on filter as well as it's bypass pressure. Will report back.

I don't believe in reinventing the wheel but I think with a little digging the spin on filter could be utilized to a greater good.

The beautiful thing about any platform is it can be improved apon. For example, the breadbox usually utilized by these 750's to overcome the inconvenience of the stock air box on these bikes, comes with inherent drawbacks. The stock air box however is not perfect in stock form. On the 78 4mm should be removed from the inside of the box where the air intake holes exist. This rectified the tumbling of air at higher rpm because in the stock configuration the air has to take a sharp 90 degree turn. With the 4mm removed this is sorted.

So like many manufacturers I have come across, don't get it 100% right for all applications. Especially when one wishes to hot rod a little.

Agree… “Research” of some is merely a thought…
I’ve always errored on the documentation side. It would be interesting to see your dyno results of the 4mm modifications.. sometimes a gain on the top comes with an expense on the bottom..

We actually have a dyno setup here now and I know the owner/operator. I will not have the ability to test each mod individually unfortunately which would be the only real way to test which mod did what.

I’m sure you feel fortunate as I do that someone left the 46year old airbox intact so your bike and mine (48)still runs. Allowing each of us to make our own mods, for better or worse…I don’t think my next mod will last 48years as the original F1 did…

Prices are crazy now. A good set of long rods cost more than the bike did when new…

[PeWe]

During the years I have seen many after market upgrade parts to CB750. That was the fun part when I bought my K6.
I learned during the years that all  parts were not an upgrade, opposite. Now 40 years and more later, still upgrading the same bike

There are people that like to make money on  parts.
Some parts for the look only, not function.

Cooling fins a good detail too.

Yes it is expensive however I come from a Harley and compared to that I consider myself very fortunate. By the time I am finished rebuilding this 78 to the way I want I will have a completely rebuilt bike for around the same money as it would of cost me to do regular maintenance work on the Harley. I have always wanted a cb750 sohc. My tastes have developed over the years from full on chopper 750 to muscle bike 750. I will be building the latter.

Agree for sure. I go into hyper research mode and try my best to separate the wheat from the chaff if you will.

I've ridden a ton of gravel roads on my Suzuki GSX-S1000 and never had any issues.  Never even had a dent on the oil filter and it's right behind the front wheel.

It is my wish that in this forum there were less reactions like yours, where others know better from experience. The latter posts have a warning where yours is trivial.

I have a dozen motorcycles in my garage that all have spin on filters save 1. And all that have spin on filters have way more miles over all types of surfaces than the “housed unit” and none have ever had an issue of “puncture” as eluded to. The shape of a cylindrical metal-walled filter is more likely to deflect debris than allow penetration. There are far more occurrences of members struggling with a corroded, stripped housing bolt than anyone ever reporting a filter puncture.

“Sharp gravel” is a ludicrous statement. Gravel used on road surfaces gets pulverized constantly by the traffic on it and is far less likely to damage a filter that is nearby than a windscreen that is farther away due to velocity and momentum.

Your “warning” is anecdotal at best and based upon a lifetime of rejecting modern advancements and principles of designs and engineering research. As for the OPs preference, if he prefers the stock aesthetic, run the housing and take precautions to avoid corrosion issues. If he prefers a spin on and its potential benefits, run that.

Find a filter you have confidence in that meets or exceeds the 40+ year old factory spec, and install it and ride the damn bike. But restricting choices to decades old approaches in the face of engineering evolution is bewildering. If you want to remain a purist to stock, that’s good with me. I’ll take better than stock because traffic, roads, and speeds today are higher than yester-century’s and I want to enjoy my time inside the helmet and not worry about my safety, reliability or performance.

"I wish there were less posts that disagreed with me and more that shared my opinion" in a nutshell.

All anyone has are anecdotes.  Mine are just as valuable as anyone else's.  If spin on filters were an issue, then modern bikes wouldn't use them.
