When you remove the XMODS pinion heat the brass gear over a lighter until it is hot to the touch. It will expand faster than the steel armature shaft and will be easy to remove. I know from experience.
One question:
If you are worried about breaking a pinion puller why not pry them off carefully with a flathead screwdriver?
I do it all the time and it works wonders with no damage. Just make sure to use a hefty one or it may damge the screwdriver.

Well, when you do it that way, you push one of the internal spacers into the motor windings, which can at best cause the motor shaft to shift end-to-end, and worst case short out the windings themselves.

Quick tip on easy pinion pulling, without any pullers:
You'll need an old, STRONG, STURDY, metal butter knife...Cut a small groove in it, big enough to fit around the arm that the pinion is stuck on....just big enough for the arm to slip though, but make sure the pinion won't slip through it if you push hard on it.
Now, lay the ends of the knife on books stacked up high next to each other, or something like that for support...take your Xmods motor and fit the pinion above the groove, and make sure the leg which holds the pinion fits in nicely, but can move downwithout force (if the pinion wasn't on there holding it to the butter knife) the groove should be resting in between the pinion and the motor can. Take a hammer, and come down hard on the metal nub that sticks out of the pinion...this should move the armature leg out of the pinion a little, and loosen the pinion from the arm. Take a screwdriver and push the leg all the way out of the pinion...presto!
I can't describe it in words enough, but hopefully you get the idea....
i tried the mode with a sb-highbred it was the red drag motor but i removed the magnates from that motor and put them in the blue top speed motor and now the motor has no torque at all i have to bump the pinion just to get the motor to go and if you touch the pinion when the motor is going it will just stop but if i plug the motor in to 2 aaa battery's directly it well start up fine but run at a low rpm and only run for about 6 min's and the battery's get really hot and i was just wondering if any one had any idea of what's wrong with it.
edit
i just didnt want to make a new post just for this.
i changed motor cans to a new blue top speed and now it works grate.

if you have a hard time getting a grip on the U clip slip a small screw driver between the small space between the clip and magnet and the can. push it down till it sticks then get a set of small pliers or some good tweezers ( i used the pliers on my swiss army knife.) and you can grab it. if you cant get a grip on the magnets tap the open side of the motor and they should move enough to grab.
