Unknown cam..?
I just opened my son's 1998 Sportster and found cams marked 15-1 24847, 15-2 24701, 15-3 24848 and 15-1 24849.
Those are seemingly some kind of high-perf cams by looking at lobes, but I could not find any information about those.
Does anybody have any information about brand and more importantly figures ?

I don't think so, as I found OEM number 25648-91 for those cams you mentioned.

neilpp is correct. Most sets of SE .497 bolt-in cams are marked 15-1, 15-2, 15-3, and 15-4. Some sets are marked 1B, 2B, 3B, 4B. The factory guys refer to that grind as the "B" cams.
And yes, they are part number 25648-91 for 91-99 models, and 25648-01 for 2000+ models.
Fourth & fifth ones down in the above table.

Likewise, the .536 cams (bottom of that list) are marked 25-1/2/3/4. And the .575 cams (second in the list) are marked 28-1/2/3/4. And the .551 cams (third in the list) are marked SE-1E/2E/3E/4E. All very common knowledge in HD/Buell circles.
If you choose not to believe us, well, that's fine. But you asked, and you were given the correct answer, twice.

The SE .497 lift bolt-in cams have been around a very, very long time. In fact, Buell shipped tens of thousands of bikes with those cams, factory installed, between 1996 and 2002 (all S1, S3, X1, and international M2 models). So they're are not some kind of a mystery to us, we've seen tons of them over the decades. The 15-1/2/3/4 markings on the SE .497 bolt-ins are very common knowledge in HD & Buell circles.
