I have the Climer manual but I don't have it at work with me. I bought new bt45s for my bike online. I have been calling around to bike shops in the chicago area and the average price I have been quoted if I bring the bike and the tires in is $100 to change them with a high of $145. I called a yamaha dealer by me and they can mount the tires for $26 each if I just bring the rims in. Is it very difficult to take the wheels off the bike? I am going to have to rig some kind of strap lift to lift the bike up but is there a lot involved in taking both the wheels off? I have a 93 ex500. I just hope these bt45s will be better than the ORIGINAL 1992 vintage exedras that are on there. I am new to bikes but it sure feels like I am riding on glass with those crappy tires on there.
