Congrats on the 100k mile acheivement. I'm also a fan of Shell Rotella oil, I've been using it for many years in several different vehicles and reading your post is encouraging. I past 100k on my BMW but that's not a surprise. My 06 FZ is just a baby compared to yours (2500 mi).
I bought mine a month ago (only 1300 mi) and the seller had already installed the following:
Two Bros exhaust (included fender elim)
handlebar risers
Puig db windscreen
battery tender lead
PR2's
Since then I have done the following:
P1X silencers
clear tank protector
foam grips...
I just installed a 17t counter sprocket yesterday and I really like it. Bought my '06 about a month ago and it already had the heavy bar ends. I would like to convert to the fz1 bars too. I commute 78 mi so comfort means everything. Love this little bike and feels so different than my bmw...
