I went into my local dealer today to pic up an oil filter. I read on the forum that it was ok to use an HD #63813-90 on my 1993 sporster. I got the filter and went to service to pay for it. The guy there knew I had a sporty and told me that was the wrong filter. I explained why I got it and where I read the info. He said, absolutely NOT. That it was unacceptable to use that filter on my Sportster. So, I went ahead and bought the reccomended filter which, was cheaper than the one I wanted to buy so, I don't think he was BS'ing to get me to buy a more expensive filter.
So, can someone tell me for sure, that filter #63813-90 is safe to use on my 1993 Sporster?

Thanks,

Mike

Hi Mike,

I found this searching HD motor accessories - http://www.harley-davidson.com/browse/browse_products.jsp?FOLDER%3C%3Efolder_id=25343743 09113179&PRODUCT%3C%3Eprd_id=845524441847795&ASSORTMENT%3C%3East_id=2534374302290363&bmUID=1148233378772&bmLocale=en_US&page=4
I think they actually recommend 63805-80A, or 63796-77A.

if that is the 10 micron filter, then, no it is not safe to use on your sporty. the oil pump does not push enough pressure. donny peterson did an experiment and used that filter on a sporty. after cutting it open, he found dry spots where the oil did not pass through. the bypass valve would open first.

the best bet is to use the filter recommended for your bike.

Absolutely correct...I too used one of those 10 micron filters and cut it
open at 130 mi. and found dry spots as well.
The 63805-80A is a 30 micron in black
and 63796-77A is a 30 micron in chrome.
After reading Donny's article 2 buddies with Twinkies decided to run
30 mic Sportster filters.
I actually had one dealer push the 10 micron on me claiming it was the
"Premium" filter for Sportsters. Thats the one that I ran and cut up to
see for my self..Very Interesssstink! But Schtupit!

P.S. Donny found that filter didn't work too well on Twin Cams as well.
Particularly when using 20w/50 Dino oil.

Guess I got lucky. Never knew there was a difference. I have 2 new filters
on the shelf. One's in a solid balck box with white lettering, The other is in
a tan and orange box.......Both are MoCo filters and have the -77A suffex,
and are 30 micron filters.

Thanks guys.........Learn something new here almost every day . :clap :clap :clap :clap :clap

There is no fitments information on my 2 boxes. Something as important as
not working properly on a Sporty is very negligent of the MoCo.

If you buy what they recommend, there's no issue....

I don't see how they are negligent....... :dunno

I see your point C,
But what about a parts guy that doesn't catch you buying the wrong filter ??
Things get busy on weekends and they just want to complete the sale and get to the next customer.

It could happen very easly.

The 63813-90T isn't the 'small micron' filter, and they are made for 1991 - 1998 Dyna EVO's.

I've used them in my WideGlide for years, and I also use them in my 1200C.

I think HD is now recommending the 63798-99A Super Premium 5 chrome filter for the new EVO Sportsters. In fact a guy I know gave me a new one, and this is what it says on the box;

"Synthetic Filer media provides nominal 5 micron filtration. :wonderlan
