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..?

The OEM bolt is not required as the spin on filter has the bypass. Yes whenever I substitute a filter I research the bypass psi.

What do you find to be an acceptable bypass pressure? The closest to stock I have found so far is 14-18 lbs

Under 20 psi and over 10 with good filter media. SOHC oil pumps are not considered high flow like say a car. This may be of interest and of educational value.

These discussions are good, sharing thoughts and experiences. ;)

Like points vs electronic ignitions.

Oil threads a must.

I recently added an oil with known high doses of zinc and phosphorus into the oil I have recently filled at last oil change.
Shifting is much smoother.
I have mixed the oils before, last time the more modern oil only as a test. A synthetic, not the more expensive ester synth. All of same viscosity.

It does not have all the lubrication additives as my bike needs, probably catalytic converter friendly modern oil .
I did not add much oil with high doses of zinc etc, 1/2 litre made a difference.

Does anyone here still run magnets from hard drives on their oil filters? This came up on here years back, strip down an old computer hard drive and there are a couple of thin strong magnets in there. Remove them and attach them to the end of the filter that goes into the bottom of the housing. I've done this ever since then, swapping the magnets over when I change filters. They always have a very fine layer of deposit on them, almost like paint, and so far my motors have been very reliable since then

I use a k&n spin on filter and I’ve had good experiences. If anyone wants to return the stock, I have the original housing plus springs bolts washers etc

Do you happen to know the part number of the K&N?

When you find a filter number for your spin on  oil filter try and cross reference it to a Mobil-1 oil filter. It seems there are different spin-on adaptations. Mobil-1 oil filters are built like a brick #$%*house inside and out. I use them on my Yamaha and  Kawasaki street bikes and also on my jet ski. Rocks and debris from the road are not taking these puppies out.

I know k&n HP-1002 is one. Will have to look up the cross reference. Thank you

I believe you can use a Wix 51390 filter as well with a thread adapter.
