Is the thread size 3/4"x16 or metric M16x1.5, M20x1.5?

also, what's the filter O.D.?

I can determine the thread size if I only know the filter O.D.

If you are working on a conversion to a standard, readily-available filter, I hope you'll share it with us!

As always, I plan to share everything that I'll eventually learn about the 650s

I'll only ever be purchasing one (overly expensive) RE filter, and only for testing and inspection purposes. I'll test it and the one already on the bike soon as I've taken possession of it

I want to know at what pressure the bypass activates, the filter components and how it's assembled before finding readily available, equal or better quality, less expensive alternatives

OkeyDokey here we go, Filter o.d. = 76mm. X  74 deep.  Oil seal o.d. 70mm. Seal thickness roughly  (  remember this one has been  used  )
4,7mm. I'm sending this on Sunday so I cannot confirm thread size untill I get my hands on a thread gauge tomorrow  but I measured approx 5 threads per 7mm. Or roughly 20 per inch.and to be honest I'm not sure whether it's 20mm or 3/4 inch.
Hope this helps. Now for a cuppa tea.

Big thanks  :)... the seal O.D is especially helpful. Any replacements must be very close to that because of the narrow pad where it seals against.

I'm sure the thread will be 20x1.5mm. And I'm also kinda sure RE is asking 30$ for the filters because they know alternatives are like hen's teeth.

Not saying anything won't turn up, haven't put too much effort in yet to know for sure. Another option is to use an adapter nipple to use the 3/4-16 filters,

something like this. 20x1.5 to 3/4-16.

Your going to laugh,  I kept the old filter to do exactly the same thing. The overly expensive R.E. filter must match something more reasonable.  I wonder how much of the engine development in the UK may have been influenced by the ex. Triumph engineers.
Just maybe we don't have to look too far ?

Haha... I'll have to look again, but I don't think Triumph filters will work. Can't remember exactly why now

Not saying that I'd recommend this, but most 20x1.5mm nipples I've seen have been cut undersized to where you could get a 3/4-16 filter on

No doubt in my mind that alternatives in the 3/4-16 thread could be found

I did the nipple swap thing years ago on my Ducati, so I could use a $12 BMW car filter instead of the stupid expensive and impossible to buy at the time Ducati one.

Smart move,  Doc. Too bad us UCE riders don't have the option.

I may need to fire up the old Jet turret lathe and crank out a batch of 3/4-16 adapters

I can get these super premium Wix Napa Gold filters locally for less than 9$. Made in the USA last time I checked. And IMHO the perfect micron rating for a 50W oil.

This one in particular has about a 14% increase in capacity and everything being equal should show less pressure drop across the filter.

It also has the bypass under the end cap instead of the dome end. A better location I think

I wonder where the expensive deluxe Royal Enfield-brand  oil filter is manufactured?  For that price it ought to be made in Germany.   ::)

Here's the list from California Scientific that crosses over motorcycle oil filters to automotive filters.

Pick a winner and the auto filters will work.

Don't know how I got the RE filter price so wrong  :-[ Someone claimed their filter was itemized at 30$ with the first service

The actual price for that filter here in the US is $13.85, it's sold as an oil change kit. I don't know if the price also include the drain plug gasket, but
they're are calling it a "kit".

From what I've been able to find so far, any filter for a 2004-2006 Suzuki Verona will also physically fit

For years Royal Enfield has sold filters, o rings and crush washers called a kit.

I bought a set of 5 filters online for $85. If I am able to ride this weekend I will put some miles and do the first oil change at 300 miles. I bet we can match these up with an easily available car filter. Thanks.
