Shoot, when I replaced the front end of my bike, I pulled the front wheel off in less than an hour, and it was not something I had done before. Seems to me they should be able to pull the wheel, replace the tire and reinstall in 1.5 hrs...but I'm stabbing. I could call the local stealer and ask him if you like?
get ready for the dealer to charge you several hours. at least my stealer would. i took in my bike to have the handle bars changed out, and they wanted to charge me 5 hours!!! i did the job myself in less than one, and i had never worked on a harley.[:'(]
Chunks-If the $110 includes mount and dismount of the old tire, I would let them do it. The wheel you chose should look nice. Let us know if it works better in the wind department than the solid wheel.
