Goldwing

The Honda Goldwing is the premier touring motorcycle.

In my opinion however, even the Goldwing needed some help.  The following are areas I thought needed improving. 

  1. It really wallowed and oscillated up and down in the turns.  I ride mostly with sport bike riders and keep up with them in the turns (not when they are full out), but the bike really wallowed and had an oscillation from failing to settle down.  

  2. The front tire cupped badly on the first set of tires.  

  3. It just didn't have quite the throttle response and acceleration that I wanted.  It cruised fine, but it felt like I could get more out of it than it delivered.

  4. It handled badly in cross winds.

  5. The straight up windshield seemed to cause a lot of drag.

 

Modifications:

Engine and front fork modifications by: Dale Linaweaver of L&R Racing in El Sobrante, Ca (510) 223-9052

Front End

bullet

Front end dampening was increased by putting in a heavier fork oil and reducing the size of the orifice.  

bullet

A super brace was added to increase the stability of the front forks.

bullet

The front springs were modified.  Basically the short spring was replaced with a piece of billet aluminum.

Engine

bullet

The intake air box was opened up by cutting two 4" diameter holes on top.

bullet

A K&N Air Filter was added.

bullet

The mufflers were opened up by removing the turn down tips and then cutting out the center of the muffler using a hole saw with an extension.  Slash down tips were then spot welded to the mufflers.

bullet

The bike was tuned to the new modifications on a dynamometer. 

Aerodynamics

bullet

A Tulsa Enterprises Windshield and Belly Pan were added.

 

Results:

Front end

The front forks are stable in turns and I get no bounce after going over a bump.  My current tires have 10,000 miles on them and so far no cupping.  With the old tires and set up, if I let go of the handlebars at 35 mph the bike would eventually develop a wobble.  Now it doesn't. 

Engine

A gain of 7 horsepower, 12 foot pounds of torque and 4MPG (I average 42 mpg on a trip).  The bike will now pull red line in fifth gear, which equates to somewhere between 125 and 130 mph.  (I didn't spend much time looking at the speedometer at that speed.)

Aerodynamics

The bike handles great in cross winds and I can get to top end much quicker (tested before engine modifications) due to less drag caused by the windshield.

 

 

Below are pictures of my Goldwing that I took with the Nikon Coolpix 900. (Taken with the Windshield and belly pan modifications, but before the other modifications.)
