I’m having starter problems I’ve replaced the battery and starter module i just bought the starter last year so I rebuilt the solenoid and still it try’s to start for a second and then the starter solenoid disengages, and it just spins any suggestions

OK, I need you to check this. There is over 50gs of vibration at the transmission on these bikes, and because when starting this terminal gets hot.

Disconnect the battery, and take the cover off the back of the solenoid .

Remove the plunger and spring. Clean the contacts while your in there.

Take a small screw driver and gently stick it between the wire at this solder joint, and see if it is broke loose. This is a common problem on the 03-04 bikes.

Somehow it seems to me that if those little wires are broke, the solenoid plunger wouldn't be energized pulling the plunger in, making contact with the battery and motor contacts. If it "tries to start and the solenoid "disengages" the plunger disc should be kicked out away from the battery and motor contacts causing the motor to stop spinning. Is the plunger spring intact and working like it should? I think I'd check the other end of the starter, where all the drive parts are also, for problems.
