I ride (older) Kawasakis, but my wrenching skills are on par with any of the old guys and probably better than many. Several years ago my bike was overheating in 110+F temps and I needed to get more air into the radiator. I made a shroud to funnel more air in by using the motel's 3 ring restaurant binder, a TV antenna I found in the weeds, a nail, a big rock and some wire. That fall I made an oil cooler for it using two Ford Tempo AT coolers and the oil gallery adapter I made by turning out a wooden blank on a lathe, built my own furnace, melted down garage door frames, cast the piece and machined it. It's worked like a charm for over two years now. And in the good old days, I wrenched on my traveling friends Sporty and shovelhead. Sometimes alongside the road even. One time they came down from Chicago and I gave the shovel a ring job before we took off out west. To get some of the nuts off the jug, I had to borrow a contorted shaped wrench used to take off a John Deere tractor starter. At least I didn't have to use a rock that time.
