When I bought the bike, I had vibration peeks at 3k, 4-4.5k rpm. I tried most of the common methods of fixing the problem (TBS, Unofficial TBS, Spray cleaning of Throttle Body, Torque the Engine Mounts, Plugs, Wires & Coils) to no avail.
I then adjusted the Front Engine Balancer and my 3k vibration was gone. 4k was less but still had another peek at 4.5k.
Since the Rear Engine Balancer was under the Throttle Body, I decided to do other maintenance at the same time.
This video is the complete how to for removing and complete cleaning the Throttle body, Seal replacement on the Injectors, doing the Engine Balancer adjustments and replacing the Water Seals on the Thermostat to Engine Water Pipe.
My theory of a loose Balancer is that the Balancer will vibrate in the space between the teeth and have a resonate frequency based on it's weight and speed in which it turns.
Model: FJR1300A 2005 Generation 1
Front Balancer Specifications: 1 Line clockwise from ~4 inch pounds counterclockwise position.
Rear Balancer Specifications: 2 Lines clockwise from ~4 inch pounds counterclockwise position.
WARNING: Do not turn clockwise beyond the specifications. This may in turn cause the balancer to skip teeth and require visual inspection of the alignment marks.
This video is in three parts:
Part 1 - Disassembly of Fairings, removal of Throttle Body, and adjustment of Engine Balancers.
