The first dealer is full of crap! I don't think I've EVER had tire/wheels balanced that didn't need some weights...
I agree, even if tyre is balanced at source, it should be checked.
How long has 'expert' been working with motorcycles?
About 2 yrs ago, local (within 50mile radius) Honda dealer tried to lay off entire workshop and become a retail outlet only American Honda got involved and prevented it.
If shop wanted to maintain dealer status they had to have workshop
A lot of 'holding companies' jumped on motorcycle bandwagon, the guy could have been selling burgers or TV's a few weeks/months ago
I found out last week from a very reliable source at American Suzuki, it's prevalent in industry at present, get a cheap manager who was laid off from where-ever and will do whatever owners want, no matter how stupid or dangerous
