Since the battery box and battery are so hard to get in and out I was trying to start it using jumper cables attached to the battery leads. The starter sounded weak. Is there just not enough juice using the cables?

Depends on the jumper cables. Most are just that,.....jumpers, 12 ga wire,.....made to have a battery in the circuit,.....not big enuff to spin the thumper, let alone have enuff reserve voltage to fire the ignition. The longer length takes its toll very quickly when working w/ the low voltage of 12 volts. Therefore if the std battery cables are 8-10 ga, the much longer jumper cables would have to be #2 - #4 ga to be equivelent.

I have another battery from a Road King which is more heavy duty. Can I use this one. It's the same voltage but more amps, clearly.

If a battery is too small......or just too old, the voltage under load drops instantly. And the fact is,.....when voltage goes down, amps go up, and hi amps causes stuff to heat up quickly. So like you said, a higher amperage battery is always better, because the voltage will stay higher, causing the needed amperage to stay lower, causing less heat buildup in the starter.
We remember the old 6v starting,......they drawed twice the amperage of the 12v, and they heated up fast too.

Well SunuvvaGUNN! Yea,, thats true allrite, so, if I run a long skinny extension cord to a, saaay,, circular saw, & theres a voltage drop, somehow the electric motor can suck more amps thru than if the V had stayed high? Im still not quite getting it, but that V down = amps up thing is sure getting me closer., I got 9 months of electronics in the airforce,,so, I know what you are saying is correct, Im just not sure how that works with a low V battery,, its sick, can it push that current thru? Im not sure yet,,

Routy, what you said makes no sense.
You can't compare a 12v system with a 6v.
V=IR and P=IV
Yes a 6v system will draw twice the amperage of a 12v... it's designed that way.
put a 6v battery in a 12v system and you get half the amps of the 12v battery because R remains the same.

Why is low v bad for a starter?
It's hard on the brushes, lower amps on a slow turning motor overheats the brushes.

Ok,power (In watts) equals current(in amps) times voltage.
The starter motor consumes a certain amount of power to operate.
Lets say the starter uses 100 watts.(Actually probably more than that,but this is an example.)
12 volts X 8.33 amps =100 watts
Now if the voltage drops...
10 volts X 10 amps = 100 watts
The starter still wants to consume 100 watts,so voltage down = amps up.
Then a weak battery can't provide any more current.Once the starter motor is turning below it's rated speed it's current needs rise and you get heat.
On the long run of wire thing,the longer the run and the thinner the wire,the higher the resistance of the wire itself is. The cord then consume some of the power and releases it as heat,instead of passing it to it's destination.
There are some other factors,but I'm just trying to hit the basics.
(Sorry,looks like vers got it in while I was typing!)
