Incarnation #2 - Dual Weber IDF Set-up

Pictured above is my 1975 Honda GL1000 Endurance Special RC-003. Surely one of the best-handling and fastest GL1000s ever, this bike is Randakk's Cycle Shakk's test mule for R&D on high performance products for the GL1000. Many items are under development. For those who've criticized me in the past for being a GL1000 purist snob, your apologies are accepted!

RC-003 was featured in Vintage Motorcycles On-line as "Bike of the Month" (February, 2009 edition)...Click here This bike has achieved near cult status on the Internet since its creation in 1999 by Mike Barone.

This bike represents my vision for the GL1000...and the design direction Honda could have taken with the original GL1000. True to the original sporting inclinations Honda engineers pursued, this bike has it all: handling, performance and comfort. In the hands of a skilled rider, this bike is a track day and twisty road demon.

I consider this bike my Gentleman's Express...artful, yet deceptively fast...a modern-day Brough Superior SS100. This is the bike Lawrence of Arabia would ride if he were alive today. But, unless you're Jay Leno, a real Brough is beyond the reach of ordinary mortals ...click here for information on the real McKoy.

I have attempted to avoid going overboard on this bike, but I may be losing that battle. The main focus is on function - not fussy attention to finish details. However, I happen think it looks great...very purposeful. The pipes are especially stunning. My bike could be duplicated at fairly reasonable expense by many enthusiasts.

This bike handles extremely well given its size and vintage...suprisingly nimble. Very predictable, neutral steering inspires confidence.

Initial Build:

  • Starting point - stock '75 GoldWing (very high serial number)
  • Front fender: Ducati early model 750SS
  • Fairing: modified 1980 Suzuki GS1000S fairing (a.k.a. Wes Cooley replica). Fairly rare item - only 700 were imported to the US.

Accel coils and wires. I used ACCEL part #140403 which is their Universal Super Coil Kit for installation on 4 cylinder motorcycles that use breaker points (or non-CDI electronic conversion ignitions like Dyna) The kit includes 2 coils, 8.8 mm wires, caps, terminals, brackets, etc. I used the stock Honda brackets, but modified them slightly to increase the spacing between the coils. Used as is, the stock brackets will allow the coils to touch each other which is not good. When I installed the blower, I switched to a different type of Accel wires.

OEM calipers overhauled with heat treated, stainless steel brake caliper pistons and EBC brake pads.

For 2 riding seasons I used an EBC Pro-Lite ventilated, semi-floating brake rotors front and rear for less unsprung weight. Fronts required minor machining of the caliper carriers for proper fit. I'm still using the EBC rear rotor.

VDO oil pressure gauge

Randakk's standard oil filter conversion kit to allow "spin-on" filter:

Since the addition of the supercharger, I'm now running a special oil filter adapter (to permit oil cooler) created for me by Bob Hagerman available here. Cooler is heavily-modified unit from '82 Honda CB900F. Also running a Think Automotive competition oil cooler thermostat (Mocal model #OT/2F-8JIC) connected via Aeroquip hoses with 8AN fittings.

Bridgestone BT-45 Battlax V-rated tires

Centerstand geometry tweaked for better cornering clearance
