Removing the wheels to change tires...

Just removed the wheels on my 06 R3 this weekend to have the tires changed...changed to Avon Cobras. (Thanks to all that suggested them) A few things I tried/noticed:

1. The service manual is helpful, but leaves out a lot of details that a novice needs.

2. Getting both wheels off the ground at the same time can be interesting!
Have a cycle jack from Sears. When placed under the motor this raises the front tire, but not the back. Read some of the ideas here suggesting pulling down on the front and that would have worked. Decided I "needed" (wanted!) a 1-ton lift for this and other projects. Found one for $129 at Harbor Freight Tools. Cheaply made, but fine for what I'm doing. Removed the seat and used a nylon strap under the frame and the upper shock mounts. Inserted the lift from the left side and tilted the bike forward on the cycle jack far enough for the rear wheel to clear the rear fender/tag without any difficulty.

3. Front tire was easy. Needed a 19mm hex wrench for the axle.

4. The manual says not to let the calipers pull on the brake lines. Found that plastic grocery bags worked well - put the calipers in and hang them by the handles on the turn signal mounts. The rear will hang on the upper shock mount.

5. The rear tire was a bit more of a challenge. The manual says to replace the bolt holding the rear caliper with a new bolt. ????? Haven't talked to anyone that does this. Thoughts??? Think this is the first time this bolt has been out (bought the bike used). What a bear!! Finally got a 14mm box-end with a long pipe and broke it loose! Used the head portion of a large lag-screw head with vise-grips in the left axle and a 24mm on the right nut. Worked well. When I went to remove the rear axle it
wouldn't clear the left stock pipe. Had to remove the two rear mount bolts on the pipe and rotate it upward. (Easy to do, but when I went to remount the bolts the CatBox had moved slightly forward. Had to pry it back a bit to align the bolts properly.)

6. Found that any bike shop could mount the front for me - the rear was another story. Some suggested they've had success with auto tire shops. I didn't. However, the local Japanese cycle shop was able to mount it with no problems.

7. Reversing the process was not difficult. Did check to make sure that the mounting on the tires matched the proper pattern on the wheels, and that I mounted the front wheel in the proper direction of rotation. (The back only goes one way; it appears that the front wheel can be mounted either direction.) Is this correct????

8. A fellow R3 owner made sure that I knew that the tire traction would be a little "greasy" for the first 100 miles or so. Glad he said something, I wasn't aware of this.

Hope something about this is new and/or helpful.

I used a massive (do not remember size, but used bolt head to determine) hex socket with an impact pneumatic wrench and it worked like a charm. Of course, I had to go and buy the socket ... who the hell keeps such a massive size in their tool box unless they are installing stoplights?
 
Oddly enough the "Christmas Special" plastic toolbox kit from Sears that I bought years ago has the huge metric sockets. What I couldn't find except from a store that specializes in tools was the 19mm Hex drive for the front axle. What a monster!!! Will use it for home protection when not removing wheels.
 
Good job Tazoom. For the axle bolt removal, I made my own tool out of a hex bolt and just screwed another nut on the end of that and tightened it really tight and then used a socket to hold it while I wrenched on the right side since that's where the axel nut is. Is the front axel bolt the same size hex head? Yeah I just did my own back wheel so far. A little bulky but managed to get it on, a friend came by just to help cause that back tire (toyo and rim) is heavy. I put the same bolt back in for the rear brakes just added a little blue loctite. My dealer is only charging me $65 to do the front so I will let them do it this time. I got an Avon for the front and of course running a Toyo Darkskin on the back.
 
The front comes off easily. The axle is a 19mm hex (mine was on a socket). Light, easy to handle. Local shop charged $20 to mount and balance. Cost me $16 for the hex wrench socket at a local tool shop. Sears carries the hex wrench sockets, but only up to 17mm.
 
Good work! And no, replacing the bolt that secures the rear caliper is not needed. Can't see way it would be. I've removed my rear tire 6 or 7 times and there's nothing wrong with any of the original nuts and bolts.
 
I think that was the first time that bolt had been removed. I thought I was going to strip the head trying to break it loose. Even had a question if it was a right or left-handed threading!! Even if you take the right pipes off it looks like the pipe bracket is still in the way. Just think somebody got a little too happy with the thread lock the last time it was put in!!! :lol:
 
The amount of "stretch" the bolt must endure must be good for one shot using the factory pnuematic impact, would be my guess. The fact that it cracks about 12 times before it loses tension means the bolt is probably stressed near the strip point at installation. Why I can't imagine since the load on it is radial not axial. I put some anti-seize on it and reused it with no problems so far.

I have a new front tire coming in this week and after I mount and balance it I'll post what I learned. I have my own tire machine (all manual) and static balancer (also all manual).

I'm going to replace the rear tire week after next and I'll let everyone know if the rear with a 225/55R16 car tire will fit in a static balancer.

As to removing tires I have a bike lift that can raise the bike 31 inches off the floor. I put a floor jack with wood cribbing under the engine, tie down the rear using tie-downs and jack the front wheel up.
