Nah , ideally the solenoid should have minimal resistance to the flow of current to the starter , as should the cables themselves . What I was getting at is that if the solenoid of the Kwaka was rated at say 30 amps and the 907 starter draws 50 amps them it probly aint going to last long before frying the contacts. I don't know what sort of current the 907 starter draws but Im thinking a 900cc V twin would have to be nearly twice as hard to turn over as a 1000cc four banger and thusly maybe the ZX10 one just aint big enough current wise . Depends on how the solenoid fails . Is it the coil that burns out/ open circuits or is it the actual contacts that fail ?. In a low voltage circuit it takes bugger all resistance to have a detrimental effect ..... which is why the new bigger better quality cables show improvements over standard old ones ( even if they are still in good nick ) . 1/2 an ohm can make quite a difference
