After 5 minutes of riding my hands are painfully numb. How much improvement or changed did you notice by adding aluminum bars, risers, Vibranators, and Grip Puppies? Any suggestions? Thanks.

I know exactly what you mean about your hands. First off, you have to relax and loosen your grip. That came from the instructional DVD called "A Twist of the Wrist Volume 2" and it really does help. Too small of glove will add to your pain also. A real good video I recommend to everyone riding a motorcycle.
The aluminum bars (first recommened Mod) were on the bike when I got it. It still vibrated bit more then I wanted so I started doing my research. The bar risers are solid aluminum so they were added just to get the bars up higher and back more toward the rider so I could sit up straighter then stock. I've had 3 back surgeries and needed to sit up straight to last all day. After tons of reading I came up with the "Grip Puppies" for $10 that just slip over your stock grips. For $10 I had to try them: Grip Covers - Grab On Foam Grip Covers - - A&S BMW Motorcycle Parts and Accessories
I didn't buy them here but you get the idea what they look like. They also helped and I liked the larger Diameter of the grips cuz I have big hands.
The biggest difference were the "Vibranators" I bought the model with the barend weights figuring from what I learned was adding weights really help also. Here is a link: Vibranator.com
It virtually removed all vibration from 0 to 5,000 rpm! You can talk directly to the owner/engineer that designed them, let him know what you are looking for and he can adjust to suit. I still get a little bar buzz over up over 6,000 but most the time I'm not cruising in those ranges anyway.
Last but not least there was one mod I read about that I didn't try and supposedly works also. Fill your bars with lead shot from a gun shop. Some people even added silicone with the shot. The cost of the shot was over 50 dollars and the weight of the bars would be conciderable. That is when I decided on the Vibranators and never looked back.
I hoped this helps and answers your questions.
