If 100,000 + miles/ 20 years of riding / 3 years of Harley shop time / 15 different motorcycles registered AND ridden are qualifiers, here it goes:
Try model specific web rings and websites.
DO take the MSF courses! I've yet to meet anybody who says they didn't learn anything from it.
Carb/jet/vibration problems are hardly unique to Japanese bikes. I could bore you with details about some of the crap that has come from Harley Davidson. But first my own experiences. My first Harley's (1984 XR1000) frame broke at around 6600 miles. Even though it only came with a 6000 mile warranty, they swapped it out. The engine leaked like a sieve - both before and after I rebuilt it. Then the oil tank cracked. My 1988 XL883 had its cam gears break off their teeth at around 1500 miles. My 1988 FXRS-sp had base gasket problems - ALL Evo motors need those about every 10,000 miles or so.
I made a decent living swapping out base gaskets, final drive pulleys (the splines strip off), charging systems (which self destruct regularly), frames (which on Softails, break around the "pogo stick tube" like clockwork around the 30,000 mile mark) and fifth gears on lots of Sotails (the shifter pawl spring breaks - and falls between the two gears directly below it while they're moving - guess which gear) and steering head bearings on those Springer Softails (they get HAMMERED like you wouldn't believe - and the "secret sauce" grease H-D came out with to "fix" the problem doesn't work). I also got a lot of business every spring from people who parked their bikes in the fall without draining their floatbowls - and wondered why they either ran like crap or wouldn't start at all. CLOGGED JETS, BRO!!!
Buells? My last bike was one - a 1999 M2! I LOVED it! But if you don't keep a real sharp eye on them, and/or don't have a good set of tools (along with the ability to use them), you are in for lots of misery.
The only people who don't have problems with their Harleys are the ones who live to park / park to live. Anything less than 10,000 miles a year ain't riding. Unfortunately, Harley's warranty (and engineering department) is counting on their customers buying their bikes to use as "lifestyle accessories" and not as a way of life - even though their bogus image and corporate propaganda says otherwise. In case you think oherwise, I love the bikes, but I have learned to hate the company and their customers from the last 10 years even more. Which is why....
If you look at what people ride who pack on LOTS of miles (20,000 + miles a year for years on end - and NOT on a trailer or the back of a truck), you will notice that they ride BMWs. My 1985 K100RT had over 140,000 miles on it when I sold it in 1999 (to buy the Buell). The inside of the engine/transmission never saw light since it was assembled. It still had high compression and used no oil - unless you used the side stand, a quirk any K-bike nut will be happy to explain.
Beginners bikes? The XL883 is darn near perfect. It doesn't have enough power OR brakes to hurt anybody. Having said that, it will kill you just as dead as one of those 200mph wonders. Stupidity kills - no matter if it is a Hayabusa, Electra Glide, Vespa, or SUV.
The best bike - and the safest bike - in the world is the one that maintains your attention to the task at hand.
I've left the road at highway speed before, and it hurts. It is even harder on the bike, seeing as how it won't heal itself. But none of them rolled over and crushed me to death.
