Wondering if a previous owner put some of the Luftmeister parts in to my FYK. It's got the nicely welded 18 inch rear wheel, airbox mod that comes out in to a single K&N air filter. Pulls strong from 4k RPM up until I don't know how high (I don't run all the way to redline). Exhaust header is factory, but it's got a Supertrapp muffler on it. Semi-related, it has a Koni rear shock.
Something new to me, was to see the 100k Mile BMW medallion on the Coil cover.
I bought it from a guy, who bought it from a friend that got it from an estate.
No, I don't really want to pull the cams to measure duration and lift.
Some photos attached in case anyone knows the specific bike.

You could look at them for some kind of part number or something about them that looks different.

I had my rear wheel widened by Kosman but kept the 17 inch size. Welds look the same as yours.
Luftmeister took stock cams, welded material on and machined down to get more lift/duration. The ones I have seen were quite evidently modified.
That air filter mod does away with the stock intake that avoids engine/radiator heat. I doubt that it helps much.
I also had a Koni shock once upon a time. It was fine until I sprang to an Ohlins.

Duckbubbles, did you intend the pun, "sprang" for an Ohlins? ;-)

No pun intended, just came out like that.
A friend and I had a lot of dealings with Luftmeister back in the day. I built a hot rodded 8 valve K engine in the late 80's using their services. I spent a load of money with them and was mostly happy with that. A mod that I liked the most was a 7%-11% gear change in the transmission. It raised 1st through 4th by 7% and 5th gear by 11%.
