Hey all, I just bought a couple of oil filters for one of my motorcycles from Perf-Form and when they came they had a flyer for a new product-a remote filter cannister for HD bikes.

It got me thinking: this might be just the thing to combine with a CB oil pump to add a little filtering.  I have a 2L motor and with the Thing shroud I installed last year I don't really need any extra cooling, more capacity never hurt (although this would probably only add about a half liter, tops) and I like the style.  Much prefer this to having a fram disfiguring my engine bay.  Also, I'll admit I've swallowed Perf-Form's Kool-Aid about their cellulose media vs paper.  I'll just need to get some questions answered about relief valves and thermostats.

Anyone got anything to add? Pros/Cons wrt this type of oil filter, etc? Input on thermostats?

TIA

David

Is it full flow or bypass filtering?  What size fittings?  If they're too small there won't be enough flow for proper pressure to the bearings- the full flow system needs minimum AN8.  Will that filter/fittings pass 3 gpm?  And remember, oil in a filter and lines does not equate to more oil available at the pick up; that's done by adding a deep sump or dry sumping the engine.

Good questions I'll be asking tomorrow. There's no dimensions on the filter cannister,* but CB lists 1/4-16 X 1/2" hose, which is kind of confusing. 1/2" hose is AN-8, but a 1/4" fitting isn't.

AFAIK, it's a full flow, but I'm concerned what that does with a thermostat inline.

Thanks.

* I have a pretty good relationship with Perf-Form, and they're a relatively small company. When I ask them about flow rate I'm going to ask if I can get one without fittings and make my own. I'd rather the top fitting be in the top of the cannister with a 90° fitting and the bottom one be a straight fitting. That way they'll be oriented properly. And I can make them any size I want.  I intend to mount it where an original oil tank goes, with the hoses running along the torsion bar tube.

If this is a picture of the actual 1/4"NPT-AN8 fitting, it should be fine. The passage in the 1/4" side looks as big or bigger than the AN8 side.

I'd need to lift my car an inch or so before I could even think about adding a deep sump.  I'd be afraid of tearing it off, as often as I bottom out now.
