Oh yea, I got a new Weisco piston to fit the bore and rings for it as well. The other reason I decided to go ahead and bore it out a little was because my original piston's skirt broke...:/
Ah and a update on the express; Well, thankfully it didn't seize up when it made that "sound" earlier. I think it just overheated a bit, which BTW is still a slight problem. Overall performance isn't really something to smile about right now, but it does run. And it still acts like the throttle is getting stuck(even though the throttle cable and slide move quite freely), but only while it is in motion. The idle is fairly smooth, but is still set a bit high since otherwise it'll die. And while it's on the stand, it'll rev itself up a bit high all by itself, unless I have the brake on. I know that I should lower the idle until the rear wheel stops moving, but right when I lower it to that point, it gradually dies. So there are still issues, the worst one being that it keeps going when I let off the throttle. But at least it does run, for now. Any more suggestions? Thanks guys for you're help so far, I really appreciate it.
