Based on the thread, is it correct that you only need a tune-up if you are having some issues - what ever they might be? I have been riding since April, averaging 100 miles/week so have about 950 miles on the bike. I searched the forums to see what people said about tune ups and this thread (though older) seems to address the issue and I just want to confirm that you all agree - no need to get a tune-up after some number of miles unless there are issues. If that is right, I will do it at some point later in the summer or before next Spring. Does this make sense?

Thanks for the help in advance.
