These people now have a Pay-Pal account. I got the flathead oil pump from them. It was shipped 7/5/10 and arrived today 7/13/10. Shipping was done by postal serivce. Shipping was 23.80 Euro's. There were no hangup in US customs. Pump looks good. Just like in the pictures on their web site. It comes with a thin metal spacer, 3 different thickness gaskets and instructions. I will get around to putting it on later this week or next. I want to hook up an oil pressure gauge and get readings before and after.

yes, let us know how that pump works out. Does it appear to use standard sportster gerrotor pump parts? Also, If you're investing in the pump with added capacity, you may want to consider adding more places for the oil to go Here's a link to the sporty pump conversion story, which also details how to add piston squirters to a U motor. With 4k miles on my Bobber 84's topend, there is no discernable wear to cylinders or pistons. Stuff to consider.

Thanks. I looked at the piston squirter install some time ago. I have about 1100 miles on the 80c.i. mill now. So far the cylinder walls show no signs of damage from looking from through the spark plug hole with a bore scope. I have babied it.

The instruction sheet that came supplied with the pump is from "CALA'S HIGH-PERFORMANCE". http://www.calas-hp.se/ . I guess VT-cycle is just a supplier. Whatever. The part looks like a quality job.

I will try just the oil pump and keep everyone updated.

hi i see those guys at calas also make titanium conrods. regads jib

Great, keep us posted.

[quote="panic"]It's not a Sportster part. The gear shown is 8/9 tooth, the XL is 10/11 (unless the newest pumps are different, but would still need the drive tang points cut).
Obviously, the choice is yours, but a pump small enough not to overload the original return capacity isn't much of an improvement (although the gerotor has smoother, less "pulsed" delivery and takes less power to turn). They could have used any thickness they wanted, so the modest capacity was a choice - meaning, if it's too small they won't sell any, and if too large there's no way to deal with the excess delivery volume without either a larger return pump, bypassing some of the feed directly back to the tank, or both.

Panic, something is not adding up. Search for "skirt oiling, again" on the forum. Frankestein referes to flow-messurements done by him self and by Jim. This indicates that the oem-pump is way smaler than the return pump capacity. Unless tests was done under false conditions? If this is not true, there is no point in the sportypump-conversion either, Have you got information on the oem-pump capacity that we have not seen?

Why?

Off his meds again ... and he doesn't even pay attention to who he's talking to!

Oh here we go again.

But I do see a way to keep the post's flowing....

Just use the quote feature when posting a reply to a thread....at least a portion of the thread will make some sense.

I got the pump installed and started the engine last night. The oil supply line hole is 1/8" NPT so some changing was in order. The mounting studs need to be slightly longer. There is a convenient place to mount an oil gauge right on top. I turned the engine over until pressure started to build before starting. That did not take long. Pressure got to 25 PSI quickly. I did not run the engine long enough to get the oil hot. I will report more later.

Why should I edit my post? It would make me look silly. I expect a message from the moderator if this is nessesary.

The post i refered to stated that stock U return pump flows 2.08 l/min at 2400rpm (messured by Woody). Frankenstein messured his -72 XL supply pump flow to 1 l/min at 2000rrrpm, which equals 1.2 l/min at 2400rrpm. Return pump is then 173% of supply pump with sportypump-conversion.

Look at this Victory-link (credit to Panic who publicated this a while ago): http://victorylibrary.com/tech/OHV-pump-c.htm

This idicates that the factory ment that 143% was a good ratio. This means that supply pump could in fact flow in the region of 1.45 l/min at 2400rpm before return pump is overloaded. Again according to Frankenstein, Jim messured stock U supply pump to 0.08 l/min. So....something is not adding up. Why is there no advantager in increasing supply flow on BTSV?

fhsmith!: keep us posted, very interesting indeed.

Now, after that response, what possible interest would I have in speaking to you?

How could you possibly think, for one minute, that you have some sort of Ownership, of UNSOLICITED Dribble, that you post on a Public Forum? Get a Grip, Oh Holy One.

Guys
This forum is all about the metal, not how far you can piss and poke your lip out. There are other forums for that.

Must be a few folks time of the month ! I've been following the thread. I didn't see any reason to butt in until now. Until deletion or editing of posts is forbidden, all own that right on this forum. It has been that way since this forum was started over a decade ago. Pa

Guys, This is the reason that traffic is so slow around here. Nobody wants to ask a question or share a procedure knowing that they will be ostracized by the few know it all's who frequent this site and have no patience for those who have yet to learn it all.

Lots of book smart and experience smart people here, to bad some of them are nothing more than smart asses. Ok…. Now feel free to rip me up for my opinion. I’m a big boy and I promise not to cry.

Sorry if this causes you any trouble Pa. I just had to say it. Alright I’ll go away quietly now.

I agree with Pa. We are all entitled to give our opinion or not. OR Give our opinion and then not.
BUT it is a bit frustrating if what may be good information is posted and then removed before you have a chance to read it.
