For those who wonder:
That is a 1931 Indian Scout. It is a 3 speed stick shift, 750 cc.It was my dads bike when I was a little kid.He lost it on a sandy curve in 1953 and hit a tree which bent the frame.It laid out in one of our fields up until about 1985 or so.My friend talked my dad out of it and spent nearly 40 years trying to rebuild it. My friend sold it back to me last year but it still would not run. I sent it to a guy in Grand Rapids Mi who specializes in them and he got it running again.I got to ride it last year for the first time since 53.It is a beast to ride. Weighs 850 pounds, has a high compression engine with kick start that can throw a man over the handle bars if it kicks back which it does from time to time.It has a hundred rules you have to observe. It has no crankcase for one, which means the engine oil takes up half of that gas tank and every now and then, you have to hand pump some oil to the engine. Give it a couple of pumps to start it, a pump now and then when ridding, an extra pump to go up a hill or if going fast.It is left hand throttle and right hand magneto advance or retard and you have to advance it, the faster you go. Left foot for the clutch right foot for the rear brake, right hand for the front brake. To shift, it is pull back for first, then two forward for second and third.The brakes are clam shell instead of disk brakes so you have to start braking sooner than a modern bike.There are lots more idiosyncrasys but those are the highlights.
