starting issues after installing a motor

swapped out my 600 to a 750, made sure all the connections were nice and tight. spins over couple times and just stops (when it does spin over its really slow, like a weak battery). took the starter off and hit the start button and spins over fine. got a socket on the crank and spins over fine. hooked up jumper cables to my truck battery same . where should i start looking? weak starter? how many volts do i need at the starter?

I'd say put a voltmeter on your battery and check for voltage drop at the terminals. Should stay around 12v when you hit the starter. If it drops way down (as in half or more), I'd have to call it a battery issue. Put it on a charger overnight and try again. If the volts don't drop, check all your connections.

The compression should be almost identical on both motors, so the 600 starter should turn the 750 no problem. Heck...they may be the same on both bikes, anyway.

Check the battery anyway. I can tell you this from first hand experience pushing a Supra across a parking lot last night. The owner had "just tightened the battery connections," and he was getting no juice to his electrical system. Thinking the battery was shot, a group of us started pushing. After about 10 unsuccessful minutes, I popped the hood and checked his connections. The ground was loose, and after spinning it 1/4 on the post...voila...started right up with the key. Check your voltages so at least you have a starting point.

If you can get to the starter with a screwdriver while it's on the bike, try to jump the connections. I know a lot of people advise against it, but it can help you troubleshoot without having to test relays. If it drags while jumping the connections, then the trouble lies in the starter. If it spins fine, I'd start checking relays. Also, check to see how hot the starter and solenoid are getting. Really hot with no turnover power has always been an indicator of a bad starter (in my experience with cages, anyway).

Did you have any of the engine covers off?
Do you have a good ground connection at the engine?

Check your engine ground cable at the motor.

Nevermind.

If you know you have a good battery, the cables are secure and you're getting full battery voltage through the starter relay to the starter, swap in the starter from your 600.
If it was a junk yard engine it may have gotten wet and the starter may have some corrosion.
If that doesn't work it's probably a mechanical issue give me a call Tuesday and I'll walk you through a couple of things.

Glad you got it figured out. You may be able to find someone to rebuild that 750 starter for you pretty cheap, depending on what's wrong with it. That way you can either sell it, or have yourself a spare.
