82 GPz750 starter clutch issue?

I picked up an '82 GPz750 last year -- my first bike. It has around 16k on the clock now and runs like a champ, but I'm having some trouble getting it started.

If the bike is cold and I hit the ignition, the starter just spins and spins but does not engage the engine.

Not knowing hide from hair about bikes, I pulled the starter and had it rebuilt at a reliable place in town, and now it just spins faster than before. Yay.

If I roll-start the bike and ride it for a few miles, the starter works just fine, though.

I'm told the problem may be my starter clutch. Does anyone have any experience with this issue? How hard is the job if it is the starter clutch or is it something entirely different?

I have years of experience wrenching on old four-wheeled hulks, but this is my first shot at a bike and I don't speak the language, apparently.

Any help would be great!

Sounds like starter clutch spring to me. Get yourself a manual off ebay and go from there.
Very reliable bike and it looks GOOD!!

Ha, thanks. Can you believe I traded two rusty Triumph Spitfires for the bike? I lucked out big time.

I have the original shop manual, so I'll do some digging on the spring and see what I can come up with. Thanks for the help.

I've just bought a GPz 750 A2 with the same problem. I bought it in England and rode it down through France and back home to north-east Spain. The bike had 26k on the clock when I picked it up and had only covered around 500 miles in the last 8 years. After riding 1000 miles on my return trip the starter clutch issue improved along the way until now there is no problem with it at all. I can only suggest that a bike that has been standing so long has gunged up the rollers and preventing them from fully gripping the starter gear boss. I strongly suggest a good blast for some distance would be worth a try as I can't imagine such a low mileage bike would wear parts that quickly. If that fails you can always resort to removing the secondary shaft and examining the starter clutch itself. A job which is a pain in the proverbial for even an experienced mechanic. Good luck

@guzziman @loudviking, I bought my first bike this year as well. It's a 1984 Kawasaki GPz 750 non turbo and i drove for about 1,000 miles on it when the starter started giving me problems. I rebuilt the starter, replaced the spark plugs (which was needed) did an oil change and it has a new battery. It seems like the known problems on these things are the starter clutches. I roll start it now and it runs amazing still

I did the starter clutch springs on my o;d kz750 twin and my KZ1000,it's not hard - you can order the starter clutch kit from someone local,partszilla or search onlne,they are still available.Springs will lose tension due to fatigue over the years and that is the most common part to go,you can either order the kit or see what's bad.There is the springs,rollers and pins. The rollers can form flat spots.Follow the manual to pull the clutch out ( it has reverse threads and if you have access to an impact wrench,use it because you have to jam the clutch to break it free) a friend told me to use the rear axel for the bolt to pull it off instead of buying a starter clutch bolt.it is behind the stator cover and thee is about a quart of oil there,it is a good time for an ouil change.It's not that hard to do,getting it off is the hardest part.

@gpzfan I'm having the same problem with mine. 28 on the clock and runs awesome, but its always a task to get it started in the morning. Nothing in the carbs, and I have it apart for a blown gasket, and I was thinking the starter clutch... Did you end up figuring out what the deal was with yours?
