Why No Mention of Sump Filter in Owner's Manual?

    That OR652 filter claims to filter down to 30 microns.

    That's getting into "paper filter" territory.

    Much better than the stock filters at 150 and 350 microns.

    Now info on the Heiden filter please... How much was it shipped to the USA?

    This is the Smedspeed modified sump fitted to mine - take a look at http://www.xs650.com/threads/hello-from-new-member.55057/


    Has the advantage of external screw-on filter. I couldn't tell you if Smedspeed ships to USA but you could always ask. They can be found at http://www.smedspeed.co.uk/

    The only downside I found so far is that because the filter replaces the drain plug, you can't drain the oil before unscrewing the filter. Gets a bit messy.

    Yeah Beags, I think I'm gonna wanna get in line for one also. Especially if you're at a similar price-point as the Heiden fllter (plus the shipping from the UK. ...that can't be cheap). Made here? Bomb-proof? Replacement parts availability? :umm: It's a no-brainer. :smoke: [ : > )

    Raymond: as I’m sure you are aware, the XS650 actually has two drain plugs:
    - the one in the sump plate to which you refer;
    - an identical plug on the underside of the transmission case.

    Frankly, I have always opened the “sump” drain first and most of the oil comes out there but I wonder how much you would get if you opened the tranny drain first....

    ...anybody know?

    Pete, same thought exactly. Getting under the bike and taking a look when I first had the bike, I was like Why is there a crankcase drain and a gearbox drain when this is a unit engine? Is this arrangement an historical artefact?

    Will be interested to see if anybody knows whether all or most of the oil will come out if the rear of the two plugs is pulled. If no answer, I'll do the experiment.

    Therein lies my main concern, is it too tight or restrictive? Are we getting to the point of starving the pump?

    5twins, how does this look for my first patch job? FYI I put a layer of jb weld on the mesh before I put the copper on as well.... Should I have connected the jb weld, as in covering the copper completely? I just don't want it to flake off in my motor.

    Epoxy will usually start to separate and degrade along the edges... or seams. By not covering the copper, you've created twice as many epoxy edges. Covering the copper would have been better.

    That looks fine. I've never had any of the JB Weld come off or break away. As long as the screen is still there, you really don't need to add sheet metal over it, just cover all the screen with the stuff. The screen makes a very good backing for the JB Weld. I only add a sheet metal patch if the screen is completely gone, as you do find sometimes in spots .....



    I have started using a bolt-on sheet metal guard now. I wanted it to be removable so I could inspect the screening under it from time to time. It doesn't block oil flow 100% but does cut it way down. I'm hoping that's enough to preserve the screen underneath .....

    I don't think so, Beags64.
    Guesstimating here, the OR652 filter looks to be at least 3 times the surface area of the side filter. I'm running a paper filter sleeve over my side filter, and a high-volume oil pump. More constrictive, more oil flow. Yes, there's a pressure drop across it. Excruciating exhaustive postings start here:

    Posts #56 to #85.

    If you assume that the oil pump could pull at least 10psi vacuum, and a 10psi pressure differential would be the start of pump cavitation (starvation), then I'm guesstimating that a cold (60°F) oil flow of almost 3gpm (11lpm) would get you that 10psi pressure drop across that OR652 filter. That's about 8,000rpm on the stock pump, 5,500rpm on the hi-vol pump.

    Flow values here, post #40.

    Once the oil warms to 80-85°F, you're well into the safe zone...

    Well that's certainly reassuring to hear. Figured if anyone would have the answer, and the data, to quell my fears it would be you my good sir. Kept thinking that a lot of people are running spin-on filters that are quite tight and not having issues but I was still a bit apprehensive.
    Burnin' up my motor is one thing. Sending out something that could possibly damage someone else's stuff, well that just ain't right! Gotta be able to sleep at night!
    Thanks for the info. Looks like it's time to forge ahead.
