Hello.
Kind of an older thread but was browsing the net and came across that pic of the DuneCycle.
I grew up in So Cal a few miles away from A.P.E. where my uncle worked for them.
He hooked my brother up and next thing I knew, the called me over to their apartment to help them "get something out".
They bought 2 kits and assembled them in the living room and got a great employee discount and assembled themselves to save cost.
We had to take them out of the patio and lift them over a fence in the parking lot.
They had the top of the line models complete with roll bars, full suspension, Kohler twin with dual expansion chambers.
We took them out to Anza and they were scary fast. So fast, I actually flipped one and the roll bar was a good accessory to have.
The Kohler was a snowmobile engine with Tillotson carburation and expansion chamber.
Keeping it dialed with Tillotson was always a struggle but when it was running right, it was a killer.
I will see if I can get pics or any other info next time I talk to my brother.
