I buy from motorcycle superstores and mount them myself. Why pay a shop to mount them when you can do it yourself?
I just shop around on the net till I find a good price, most with free shipping if you buy a set. I have the tools to change them myself. I use Dyna Beads for balanceing, just put them in and they are balanced. when I change tires I change the Dyna Beads along with them, just remove fron old tube or tire and put in the new.
dyna beads, i'm gonna have to give those a shot. i was just going to use that liquid tire balancing shit you get at the autoparts store.
I buy my tires from my local Yamaha shop, he will order any tire I want, if there is a problem, then it's on him.
BTW, my Yamaha dealer has been here since the mid 70s, he keeps parts for the old XS650s in stock. I have purchased from him....OEM petcock, cam seal and gasket, the oil pan gasket, and the seal behind the front sprocket. He claims to have enough parts to rebuild two XS650 engines.
