So my starter motor on my CA95 is working now, but it doesn't spin the engine. Chain turns but something in the gear behind the alternator isn't engaging. Is there any option other than removing the alternator? I'm hung up on the points cam, bolt on end of crank doesn't want to loosen. Is it a conventional tyoe thread or reverse? I'm always worried about bolts on shafts.

The flywheel bolt is conventional. Usually you need an impact wrench or with the bike in gear with someone sitting on it, you can get it loose. You can't use (or should not use) a wheel puller to get the flywheel off. You will need a fine thread metric bolt that fits the flywheel opening threads. Wrench the bolt in and the force of tightening will drive off the flywheel.
Check the back of the flywheel. That's where you can start to look for troubles. Make sure the rollers are not missing.

Another way to get the flywheel nut off if you have the motor out or at least have the chain off is to put it in gear and use a pry bar between the bolts that hold the drive sprocket on. it is actually easier than trying to keep the rear wheel from spinning.
my alternator was damaged by a PO using a wheel puller incorectly. It can be done but you would be money ahead to get the correct puller than to use the wrong one and damage your alternator.

Here is a road map to what you need to do here.

Impact will take that bolt right off without a problem - at least all the ones I've done.
Getting those flywheels off is a big hassle. I usually use small crows feet type prybars, one on each side. Then just loosed the flywheel bolt up a couple turns. Then I just apply pressure on the prybars and whack the flywheel bolt a couple times to pop it. It is a game of twister doing it like this if you don't have an extra set of hands to help. Make sure and use a torch to warm the whole assembly up first to make your life much easier.

OK, I guess I'm not doing things right... I removed the screws holding the stator base and tried to remove it. Guess the magneto should come out first, since there is a backing to the stator base (duh). Then the flywheel comes out, in order to get to the starter clutch. My real question is without disassembling everything, what would cause the starter motor to spin and not engage the engine? Wonder if it maybe it is temporarily stuck from years of disuse, and if once I get it running it will free up.
Because the starter clutch is malfunctioning. The rollers will roll one way only. If the springs are broken that hold the rollers to keep them going one way... well then the rollers will allow the clutch to spin both ways which is where you are at right now. I hope your starter clutch mechanism isn't cracked because those are typically really hard to find. If took me years to find one for my CB72 (Superhawk 250). I have seen the springs pop out completely after getting pinched so they might be missing. You'll find out when you get it apart!
