I made the mistake (good fortune?) of venturing over to the dark side of the Pelican board, the R1100S forum. I'd always wanted a BMW twin after riding friend's twins and working in a shop almost 20 years ago that worked on them. I figured I needed something to play with while the 930 is down for an engine rebuild, so I bought a '99 R1100S. It's certainly different than the jap bikes I've ridden over the years. The handling is great, but it was a little buzzy and the idle was erratic. I put a Two Brothers cat bypass on it and adjusted the low and high speed vacuum. Adjusting the vacuum balance helped some but the cat bypass seemed to help the buzziness and the idle. Since I left the stock silencers on, it's not really any louder. I do like the RT though, if I decide to do more distance riding, I might move up to an RT and hand the S over to the wife.
