I used Mobile 1 synthetic and found the transmission to be much quieter but noticed that I began to develop small leaks through several gaskets. Although the oil chemists say this should not be an issue I have since switched back to Rotella and change it twice a season. Do not use heavy oil like 20w-50, for although it will run quiet, you most likely will have starter clutch issues causing the starter motor to free wheel a few times before it engages, and some have found that it will be difficult to disengage the clutch enough to shift out of neutral. Do not use an oul with friction modifiers (shown on the label) or you might have slipping clutch issues. Whatever oil you use, change it frequently and regularly since it has a huge job to do with the engine, transmission and clutch to lubricate and cool.
+1 on the irridium plugs, NGK.
+1 on the external alternator, yours WILL fail eventually. Some have even had replacement stators fail, plus it is nice to have more amperage available than you can use.
Tires are subjuct to opinion, but many folks swear by the Dunlop Elite 3. Very good on tar snakes and metal grid bridges. The odd size of the 1200 rear tire makes the options somewhat limited with all but a few manufacturers having dropped that size. The best remain.
The 1200 has only a few faults, one of them being a somewhat noisy transmission but it is still a class act.
