    They need to shorten the swinger and run some laps at PineLake. Thanks for the link.

    similar build from a few years back

    I bought this 86 R back in San Diego in 2007. The previous owner said Duncan built it ground up. Alot of things are similar parts this build used including the swingarm, axle, billet Duncan kickstarter and shifter, break lines, motor parts, carb, pipe and silencer. Not sure if of the bore size. Freshly powder coated frame and new rear suspension. 4in over roll desing swingarm. Dominator adjustable axel, all chrome!. Front forks redone. Engine has an eliminator 88 cylinder port-n-polish with pryamid reeds and a 39 carborator and k&n air filter. Powerhead exhaust has been double flanged and is mid to high power range.

    Great read, except the part where they said they cut the OEM fenders.
