If you are talking about removing the lower chrome stantions, then yes, you can do it at home. Like you I bought some 2nd hand forks for my R. They were advertised as ready to go. Well, the chrome lowers were discolored and had striations on them. I wasn't sure whether or not new seals would hold up, so I replaced the chrome tubes.
On the TLs, there's a small set screw on the inside of the fork. It's heavily Locktited in. I went to the local home center and bought a MAP gas torch. It's similar to propane, but burns hotter. Anyway, after heating up the screw, I was able to back that out. The heat also helped to loosen the Locktite holding the chrome lower into the lower caliper fixture, also the part the axle goes through. I used the axle to unscrew this from the chrome lower. One word of advise. Get a small dremel stone. Make it a little smaller than the set screw (if the GSXR forks have it). The set screw threads down into the threads on the chrome lower. If you don't grind that thread down a bit, you cold risk screwing up the threads in the caliper mount. Also, I didn't bother to put that screw back in. I Locktited the chrome lower. If that fails, that little set screw isn't going to do anything for you anyway.
Hope that helped.
