I know it sounds crazy, but you may want to check the voltage regulator. My
eldo has a Bosch and the starting circuit goes through the regulator. My
bike did the same thing a few years ago. I replaced the solenoid and relay
and no change. It would just do it every now and then after the bike was
warmed up. One day it happened to do it when I got home from a ride and
tried to re start it. I took out my volt meter and noticed that when I
tried to restart the bike the voltage at the battery dropped to around 8
volts. I started looking at the wiring diagram in the yellow manual and
notice the circuit went through the regulator. I swapped it out and
no more problems.

One more thing you might try is swapping out the battery cables to a larger
gauge and make sure the ground to the battery tray is clean. It you still
have the stock cables they are probably shot from age.

good luck

Hi, all. I'm a new loop owner and new to this list. Picked up this '73
eldo in Oct, it had sat for a number of years but was in good physical
shape, no corrosion. Had to do some rewiring, replacement of rubber
parts (fuel lines, airfilter boot, etc), cleaned carbs & tank. Finally
got the engine started with the right plugs (NGK BP07ES's won't cut it
despite advice to the contrary). Problem is, after running for a bit,
enough to get hot, if I kill it or it stalls it won't turn over until it
cools down a bit. Hitting the starter just gets a "click" at the
regulator. After waiting 5-10 minutes it will turn over & start again.
Could this be a problem with the solenoid? I'm thinking that something
is getting stuck open when it gets hot, and electrically the only thing
that should be getting hot is that solenoid because its the only part in
the electric path that's mounted to the engine and would get hot when
running.

Anyone have any ideas, set me straight before I take a wrench to that
thing and start disassembling things and losing screws.
