The $90 didn't include a new tire? If it did, that might be a good price. If it didn't, that's ridiculous.
My local Honda dealers shop wanted $30 to replace my front tire with my new Dunlop if I brought in the wheel.
The local Yamaha/Suzuki dealers shop wanted $17 to do the same thing.
Guess who doesn't have skinned up knuckles and is $17 poorer but is happily riding around with a new front tire?
Revisiting the tire change prices... I just brought my front tire down to the closest motorcycle shop to get it mounted, which is a Honda dealer. They charged $25.
I said "wait... isn't it cheaper when I bring in just the wheel?" Their response was "yes, we would have charged you $40 if you brought the bike in." So $90 for changing both tires on the bike is sounding more like the new norm.
I know there are 2 other shops that will do it for around $15, but I was in a rush and they're another 10 miles out. Even $15 is more than I like paying... It takes them a whopping 2 minutes and no materials. But it is worth it for the convenience I guess.
Back on the topic of fork work: I was going to remove my lowers and paint them black to better match the military style of the bike, but after reading about how difficult this is I think I'll just mask and paint them in situ.
