Im sold on Jims suggestion of the Magnefine filter.

Does anyone know where to source these in the UK / Europe?

And to Jim: point taken re gas forming from liquids under negative pressure and heat. By total coincidence, this came up on a recent project I'm involved in (an automotive water pump design) at work and was backed up by our 'boffins' !!

If the filter is on the return line then no crap should make it to the tank.
When I say my filter is on the pressure side, I mean it is plumbed in between the pump and the crank like all modern oil systems -so nothing but clean oil can get to the crank. Jim

No doubt installing the filter between the pump and the crank is the best way.

BTW you can get rid of one the crossover rocker oil lines on the head annd eliminate one banjo fitting and potential leak by grinding the hardening off the blind ends of the intake rocker shafts, drilling the ends of the intake rocker shafts so the oil passes through from one rocker shaft to the other and then on to the right side rocker shaft. There is still more than enough oil getting to the front right rocker.

Yeah that's been done long ago. Then I use the extra banjo on the side of the head to connect my oi pressure gauge. Jim

I did a quick search and nobody came up to tossed it in ebay. Seems like USA and Oz are about it.
But they can go by mail it is just that post fee is equal or greater to cost of filter. Maybe you buy
more shipping less. Shipping is getting to be expensive as of late.

Funny old world eh? Must be loads of different filter options over here that would suffice. But I've still gone and ordered some from the good ole US of A for my Norton over here in Blighty! Thanks for the link Onder.
 
Is that 3/8 magnefine on ebay the smallest one which will work in this application? Do they have versions with different body sizes and flow specs?


So the only disadvantage of the magnefine is the high filter cost?
Maybe the best solution would be the standard setup with a Filtermag magnet around the filter.

Actually, I did not like my standard screw-on setup because I think the location is subject to projections from the road/tire.
 
Had this mounted when the bike was a 750 before converting to 850 Mk III spec:

Takes a standard automotive filter (forget which) If anyone's wants it, let me know. Cheap sale or trade.
 
Did once before and nobody bit. Don't really have a price in mind. Thought anyone interested in adding a filter might see it here. BEsides, f/s adds fall off the table after a while. This will be here for anyone who searches "oil filter"
 
Although simplicity may be the ultimate form of sophistication, this one looks a bit too simple. A natural gas fitting and a couple sawed off galvanized nipples jammed into a casting may make a good, usable gift to the needy, but I kinda understand why it ain't moovin there, jethro. :p

Oil filters are a great help in filtering the not so small particles that may get into the engine oil however. These not so small particles may come from parts chipping or failing or out of a dirty can, oil tank or funnel. If they are not filtered out and are allowed to circulate they will do immediate damage the the insides of your engine. Jim

please, I would like to read the rebuttal to Jim's above statement from those who deny childhood vaccines and oil filters?

Seems like you are primed and ready there 1up3down. Blast away.

oh, tiss not I who argue against oil filters

I am hoping Hobot will chime in, again, this time to refute Jims' latest defense of the use of oil filters on our motors

but thanks for thinking of me!
 
Back when I road raced a Commando based bike we ran a HUGE filter in the return line.
For an adapter, we just used off the shelf parts meant for VW's mounted under the carbs. This setup increased oil capacity by a quart which, along with the cooler we always ran helped control oil temps along with keeping the oil clean. Overkill for a street bike unless you live in a very hot climate, but I would NEVER run an engine without oil filtration unless it's a lawn mower.

Well, Pete, my name's Dan and it worked just fine. Nothing's "jammed" anywhere, the nipple's are threaded in and the brass fitting is exactly what one would expect for an oil filter. It's very similar to the one that came on Mk III's, when Norton finally got sophisticated enough to put an oil filter on. And though I'm sure there are nicer, more expensive kits out there, this was an economical but workable alternative before they existed. I'm not really trying to "move" it, just offering it up to anyone "needy" enough.
 
Pointing at an elephant.
Standard Combat and aftermarket crankcase breathers return oil to the oil tank without any effective filtration - defeating any justification for return oil line micron filtration. Once in the oil tank, largish particles can then be strained at the tank banjo bolt but the minute particles are straight through the oil pump and into the crankshaft and rocker feeds.

Hi danno.
I am not 'needing' another filter base but luv ya work!

One of the modifications on my bike is machine work on the timing cover to re-plumb the oil system so the filter is on the pressure side of the pump -between the pump and the oil supply to the crank and head. So anything that was caught by the filter had already passed through the screen in the sump plug and the screen in the oil tank.

Would really be interested in seeing what is involved here.

Good point. Ideally, a filter/magnet or t-fitting should be put here too but I suspect one of these breather/valves cannot overcome the back pressure of an in-line filter, if a filter was run between it and the tank.

Also, I am not sure what micron level the Magnafine does, but I suspect in the 40 micron range which is probably not as good as a quality spin on. BUT, it has a high power magnet which probably traps particles at a lower than 40 micron level.
