Okay guys this is my first post here. So hopefully I do this right.

I have a project race car with a 06 GSXR 600 engine in it. I have had nothing but electrical issues putting this thing together and I've kept everything as stock as possible. The only things not stock are the on off switch and ignition. those are custom but they all work and dont pose problems.
I have a brand new battery and good voltage there 12.89V. I have a brand new starter and everything seems good there as well. When I go to start the motor it is very slow as if the battery is dead or dying. I get maybe 4 total cranks out of the motor and then it's dead. it won't do anything. it clicks and makes a grunt trying to turn it over but I can't do it. Any ideas any help it's all appreciated. I'm waiting for my new rectifier to get here to see if that helps I've checked every maintenance manual I can find for any troubleshooting tips but nothing seems to work. Thanks in advance

Check the battery voltage while cranking. If it drops to, say, 8-9V, then it's probably dead. If it stays more or less constant, there must be resistance between the battery and starter motor.

It drops to like 7V im thinking its toast. I am charging it once more really slow. Thanks for the info

You can try charging it, but these motorcycle batteries don't take well to discharges and recharges. It seems once they discharge, even if not fully, they don't recover well. In my experience and for piece of mind, grab a new one.

Is the voltage still dropping to 7V while cranking? Check the power and/or ground connections of the starter for loose, rusted, or dirty connections. Also look for signs of overheating, like fried wire insulation, etc.

Well if there's still a big voltage drop with the fresh battery, it means a lot of current is being drawn out of the battery. But if the starter isn't turning as it should, where is it going? If the wiring between the starter and the battery seems fine, the only thing I can think of, would be a partial short inside the starer. Perhaps you could try jumping the starer straight from a freshly-charged battery, with well-connected, thick wires. If it still won't turn, you've eliminated the vehicle electrics, and need to look at the starter.

He's got an 06-07. Would a bad rectifier show these kind of symptoms?

The R/R should not come into the picture when the engine isn't running (or at least rotating in any case), unless it's partially shorted, but then it would drop the battery's voltage even with the ignition switched off.

Still, disconnecting it before operating the starter might be worth a try.

It might also be worth a shot, to measure the voltage at the output of the starter relay, while pushing the starter button, but with the starter disconnected. If the voltage still dropped, it would be indicative of an internal short, but I would expect it to melt the relay in short order, if it existed.
