I have a question. If your BMW's are so poorly running in stock form then why buy one? I hate to be cheeky but I have a hard time understanding the big modification craze that seems to permeate throughout the motorcycling community. Having ridden many R1100S models thanks to kind friends and never noticed the poor fueling situations some of you are referring to. Also having ridden a stock model at the track I can say that it certainly isn't underpowered. The only bike I have modded has been my RC51 and only for racing purposes. Otherwise I would have left it stock, especially for the street. Most riders on the street don't use over 100 hp. I have usually used a 500 c.c. bike making 45 bhp for the street and had no issues.

Having read the article I would think that you guys/gals may find the recent article in SR of interest. It involves the tire dimensions and how they can affect dyno readings. Dyno tests while of some interest aren't everything as some have said here. I don't want to get into the obvious personality differences between Dr. Curve and many of you but I think if you read his initial post all he is doing is saying that alot of mods don't give you much.

Due to a seized bearing in my RC51 I had to get the motor redone under warranty. I decided at that time to get the motor work done. This was a $12,000.00 Canadian job that I got for $7,000.00. This included HRC HC pistons, port/polish, cams, full race exhuast, etc. All of this gave me a gain of less than 20 hp. On the track it was great but on the street it was unruly. It required more maintenance and was a tempermental b*tch. I'm not saying the Mfg's are perfect and that the fueling is perfect. We all know they keep them lean in order to get through emissions but I do think some of the claimed gains here are ridiculous.
