What exactly do I have?

Hello, I was wondering what specific model of carb is on the 650R. My info says 40mm, but I couldn't find a Keihn (sp?) that is exactly 40mm. Is it the PWM? Also, I'm wondering if anyone knows of any other discussion boards for the big XR. Thanks for the help. Jon

The carb is a PE78A unless you live in california, then it's a B. There is a group of over 500 650 owners at Yahoo groups, formerly E Groups.
