hot cable and ground cable:
2 is OK
1 is good
0 is better
00 is best
What gauge cables do you have?
Make sure connections are clean and tight. I use a highly conductive anti-oxidant grease (available from NAPA, etc).
Is the ground run to a starter bolt, or to the frame?
If to the frame, what is the gauge of the ground?
Is there a ground from the frame to a starter bolt or to the clutch housing? What is the gauge of this ground?
Hot engines are sometimes a little bit tighter.
Hot starters are a little bit less efficient (supposedly).
Every piece of the starting system can affect starting.
