My 1800 starts to shift rough when there is about 2-3,000 miles on the oil, so I change the oil and filter.

They also histoically shift harder, like a "clunk"

Sorry to hear you are having shifting issues.
Since I also have the 07 maybe I can help with a process of elimination.
Oil: at correct level and changed using the specified weight.
Clutch disengaging properly with no hangups. Brake fluid changed to new DOT#4 if possible.
Shifting: stock shifter or heel and toe? If heel and toe you could possibly be slightly miss shifting. If the stock shifting arm is used check that all gears can be engaged smoothly with no hangups analyzing each gear shift.

I sensed a slight shifting issue and found my shifting pattern was out shifting the clutch. Also, I shift at 3k rpm from 1st all the way up traffic and spd limits allowing. Another thing that works for me is cruising between 2-3K rpm just seems to be smoother.

One point to remember we are riding the 1800 and the transmission is very noisy and clunky. Add to this noise is the alternator drive and valve / injector clatter. All good noises mind you, it's the normal 1800 tune.

Noticed that the bike has just a few miles, it needs some more. Go out and putt some more on it. Oh, forgot get yourself a good shop manual so you know what to look for. (I bought the manual before I bought the bike)

Let us know your findings or PM me.

I have tried several different oils in my 1800 and have found that it shifts best with Rotella T5 10/30. Try it if it is available where you live.

On models from 2006, the larger alternator is much noisier.

One of the things you might also check is your clutch lever bushing. If you havent cleaned and greased it since owning her it does make a slight difference. I do mine every couple of years. The other thing you could look at is when was the last time you changed clutch fluid and bled the clutch unit.

Lots to be considered on the above statement of flushing out the old crud. Down here with all the humidity I do this annually with Speed Bleeders and still purge out crap. As for maintenance of the clutch lever, good call on this too, especially in dusty conditions. Included with the clutch lever maintenance is the limit switch that signals clutch actuation. The contacts corrode creating FUZZY operation on starting in gear.

Thanks for the reminder Bigmick.
