I replied to your PM just now, but I'll post up here since it might help with any confusion that other have with installing the front wheel. If you have any other issues, let me know and I'll help you out. To clear up and confusion, these are custom spacers I made for these wheels to fit the RC51 (they are originally for a CBR929/954).
The SP1 and SP2 both use the same wheel spacers, bearings, axle and center collar (the part that goes in between the bearings inside the wheel)
The procedure for installing the front wheel is as follows:
Take the wheel, put the spacers on and put it in between the forks and slide the axle through.
Install the axle bolt on the right side and torque to 43 ft lbs
Install the axle clamp bolts on the right fork and torque to 16 ft lbs
Install calipers and torque bolts to 22 ft lbs
Put the bike (or at least the front end) down on the ground and hold the brake while pumping the forks down and back up a few times to seat the axle.
Make sure the index line on the left side of the axle is aligned with the outer surface of the fork leg.
Install the axle pinch bolts on the left fork leg and torque to 16 ft lbs.
The reason for "seating" the axle is because the left fork leg basically floats on the axle until the pinch bolts are tightened. This is done to prevent the forks from being pinched or spread at the lower end vs the upper end. If this is not done, there will be additional friction between the fork sliders (chrome part) and the bushings inside of the upper fork due to them not being aligned perfectly. When you bounce the forks, it allows the left fork leg to move to the correct spot on the axle.
When you install the axle bolt on the right leg and torque it down, the thicker portion of the axle (on the left side of the axle) is mated to the left spacer. This means that when you torque it down, all of the spacers and bearings are pulled tight to the right fork. At this time, you can still take the left fork leg and move it back and forth. It looks like there is a gap between the spacer and the fork because there is. The left spacer doesn't sit against the fork, it sits against the thicker portion of the axle. In the picture above, you are seeing the axle in between the spacer and the fork. This creates the illusion that there is a gap. The easiest way to visualize this is the install the axle in the wheel and just the right fork leg (you can spin the bottom of the fork around and put the bolt in and tighten it all up).
