Per Wikipedia - "In 1996 Motorcycle Consumer News measured 31 horsepower at the rear wheel of an LS650 Savage, and a rear-wheel torque of 30.5 pound-foot. The LS650 registered a quarter mile time of 15.3 seconds at a speed of 81.1 mph, and an average fuel mileage of 55 mpg."

These numbers seem believable and align with your dyno.  But, I've seen other sources mention 37 lb ft at 3400rpm.  I'll go with your numbers and Wikipedia!!  It appears you made max torque around 4700 which seems right to me.  My butt dyno says torque is modestly greater at 4700 and not 3400.

The nearby HD shop will only run dyno on HD.  I've only found one other place in town that will deal with Suzuki and carburetor bikes.  I can't even get through on the phone to them.  Crazy busy place.  Yes, the camera is the way to go.
