Mate there is a mod to bypass the coils so it turns over a few times before it lights up , that has helped quite a few guys over the years it's in my old PC though , it's not a hard wire up either.Gooogoool knows .
You've obviously replaced or fixed anything that might be holding you back does the starter get really hot ? That will show if it's not happy the starter staying on is a clue too, how's the center tank switches all good ?
Sometimes it's something you just haven't thought off.
Try shorting it to start at the solenoid man use a big *** screwdriver see if it turns freely that way.

Starter does not get hot. I will have to look for this solution. Thanks.

For the hell of it, do a compression test and post the results. It's cheap and it's quick.
Remember disconnect power to coil, remove both plugs and throttle open 100%, note first revolution compression and 8th revolution compression. Also how does it turn over with plugs out?
Let us know... Post it...

Hey Tups, et.al:
Well, if I was gonna look at it, I would take my meter and check the voltage directly across the battery terminals when cranking. What is it? , Then alligator clip the negative lead to a good ground point near or on the starter or primary, take the positive lead and alligator that to the battery terminal on the starter, hit the starter button and see what the voltage is there. Is it the same as across the battery? If it is not real close, start going backwards from the starter and see where it drops.
I don't think the solenoid design on our bikes is all that great. The switch itself tends to get carbon buildup. Also, comments on the bearing in the primary above would be a good thing to explore if you can't find any electrical issue.
And my bike does it sometimes also. Especially when the battery is getting a bit weak. My bike is a battery killing machine. I go through about one a year. Two years is "Wow, that one lasted a long time."

Even though you have that great all ***** starter...it still uses the crappy factory gear reduction which is a poor design.
Spyke makes a starter for that bike with a different gear reduction that will spin that motor faster with less battery...but they are proud of it. (pricey)
Ultima makes a copy of the Spyke starter...I have had one for 6 years and have yet to kill it.

Can't imagine having to replace the All ***** one, but maybe....
I will give this some thought.
Not doubting you, just wanted to educate myself more on this. I went looking for information about Spyke's gear reduction that will spin that motor faster and didn't really find anything. Do you have some reading material you can point me to? Also, how did you know that Ultima is a copy of the Spyke one?

Spyke claims 46% more cranking torque than stock using a standard battery...first time you push the start button you will believe it...my Harley starter wouldn't turn it that fast with the plugs out...
As far the ultima being a copy...look at the two and make your own decision...

Looks like that "Spyke Super Torque" with 46% more cranking torque started in '89 with the later model starters...
But it does look like the ones for my model (1987) are "1.4 Kw rating, which is up to 200% more torque than stock. In-creas-ed cranking speed and low amperage-draw design delivers fast, reliable starts with less battery drain."
According to their site anyway. I will give them a buzz and talk about the different gear reduction.
In the mean time I would expect that an All ***** should throw over a 1340 without much effort. So I still think I have a problem elsewhere.

The hole on the trans is too small for the newer starter...I have heard you can get it machined, but never tried it.
