I would first measure the volts directly on the starter.it should be above 11 volts while trying to crank the bike.
If it drops off,load test the battery.
If it stays up,remove all 4 spark plugs to unload the engine and crank it again.
If it now spins,go back into the starter.
A bad starter can free spin on the bench and not spin with a load on it.
Posting a video helps,or at least voltage measurements before,during and after the test.
Be sure you measure the volts directly on the starter post and engine case,not at the battery the first time.were interested in if the battery volts are actually getting to the starter.
Corroded ground lug at the frame or a bad solenoid can cause your problem too.
If you suspect the solenoid,you could(carefully) use a screwdriver to short the 2 posts to crank it.
Assuming the battery is OK.
One last thing.if the engine does not compley turn over,there is a chance that one cylinder is hydrolocked.Be aware if you pull the plugs and crank it in a hydrolocked condition,it will shoot gas out that cylinder quite a distance.Flamable too so KILL the ignition while testing this.

I've been having issues with starting too, and the hydro-lock comment by virgilmobile got my attention! (by the way, I'm totally new here -- back on a Wing 25 years after selling my first and only one! No forums back then :D) Can I ask a question here, or does that need to be moved to a new post? I'll ask and you can re-direct it if necessary...

My cold starts are always great -- cranks well and strongly. Once the engine is warm if I start again within about 3 minutes it is still strong. But if I wait longer (like every time I fill up with gas!) I have to "bump" the starter 3 or 4 times before it will crank. Once those "bumps" are done, it cranks great...

Any ideas about how to fix this?? The bike has 98K on it and I drive it 100 miles a day round-trip to work. It has averaged 48.5 mpg since I bought it at 92K in July -- and I absolutely love it! But I kinda hang my head at the gas station ...

thanks for any help you can offer ... BTW, mine is an '81 model

Usually when a warmed up bike has problems cranking(slow) I point the directly to the starter,after the battery is confirmed OK.
The 1100 starters use bushings in most of it.They dry out and really need to be cleaned,inspected for wear and renewed.Makes a big difference.
The 1200 moved to mostly a roller bearing design, but still had one bushing in it.

Thanks for the thoughts about the starter. I hadn't suspected the starter or battery at all because 1) it starts very strongly when it is cold, and 2) when I crank it warm it doesn't crank slowly at all -- but rather cranks for a second and then stops suddenly, like the engine suddenly froze. And then when it does crank right, it cranks very strongly.

I WILL check the starter, as it might be ready for refreshing at this mileage ;) but for my information, is there anything I can do to eliminate the potential of hydraulic lock? Or is that just part of these bikes? My previous GW was a 1976, and it started and ran flawlessly, so of course I expect the same from this one too 8-)

If you have to bump it a few times to get it to crank,there are 2 possible problems.
After stopping and setting on the side stand,a leaking float needle MIGHT be flooding a cylinder with a little fuel.Bump the starter a few times squeezes out this small amount of fuel and the it cranks normal.
You could verify this by turning off the fuel when you stop for fuel and put the bike on the center stand...see if it cranks easily or still needs to be bumped a few times.
If it consistently fixes the no crank problem,its hydrolocking.
If it still has a problem,get back to the starter and electrical,including the solenoid.

I'll certainly try that sometime this next week. Since this is my main transportation (because of fuel economy mainly) I won't touch the starter until I can get a long weekend. Before I bought the bike a couple months ago I have no idea how long it sat idle. And the guy I bought it from "found" it in the garage of a house he bought, so I really have no history on it. Now why wasn't I the one to find it?? :(

Thanks again for the help and ideas. As I've browsed this forum, it seems I'll be spending a lot of enjoyable reading time here!

I finally got my starting issue resolved (I hope), and suspect it was a variety of intermittent issues. Rebuilt the starter (the brushes were just a pile of dust) and it was better, but that didn't solve it. Cleaned the start button contacts, which were VERY dirty. Still intermittent. Took out the cables and soaked them in water / baking soda, then coated the terminals with Vaseline. Removed the solenoid and banged it a bit. :roll: After putting it back togther, for now at least, everything is cranking first time, every time... Here's hoping! :roll:
