Starter specs ?

[fastfun]

Is someone familiar with the amperagerate of the starter ?

@fastfun check this thread out for a huge amount of starter related knowledge: Inexpensive Starter Replacement

Is someone familiar with the amperagerate of the starter

as a loose rule the starters use about 1 amp for every cubic inch
so the rocket should draw about 140 amps because it is 140 cubic inches.

Are you sure that's not watts?

i have a gauge for checking amps its range is 0 to 600 amps dc
i checked my rocket but that was a long time ago so the info is in my brain but the connection is gone lol
edit
a bad starter will peg the gauge

Wow, that must be unfused, my whole house AC only has a 50 amp fuse, I can't picture a 200 amp fuse on a motorcycle

they are not fused
the starter solenoid takes most of the abuse the solenoid washer looks like it was copper welded from the sparks.
that is why you need a larger positive cable to flow the amps so if you didn't have a starter you bat cable would be very small.

You mean 'thicker' with 'larger' positive cable ?
next, a more powerful starter does need a thicker positive cable you think ?

If I remember, it's the ground that's the weak link, when I upgraded my starter, I put in a heavier ground wire.

I am not good at explaining so will try again.
On the battery cables they need to be thick to flow the current/amps but the rest of the bike electrical system is less than 30 amps and is fused with a 30 amp fuse.
On my bike i think that the negative cable was going bad so i just added another cable to it and that helped a lot.
When I upgraded my starter i never gave it a thought (until your post) lol
It works real good and might work even better with a better positive cable.
