CrazyHorse is correct, very few are balanced from the factory. Most dealer don't check before delivery.
Second, if not occasionally check how do you know they're balanced? If they never get out of balance, bravo!, bonus points!. If out of balance, you're dating a homely girl.
Lastly, a CarbTune isn't cheap, but it's worth having especially if you have friends that ride classic Triumphs. Mine has been used on thirty bikes of friends and family. It's been well worth the investment, it's probably the only reason most even talk to me.
