Well, after 3 years, I have given up on the ZipTy kit for the KX500. I have been through 3 tanks in 3 years, and all three have cracked. While ZipTy was helpful the first 2 times, they have not responded to my last email, so I guess I am done with the tank. I really don't want to spend almost $300 every year to keep replacing my tank, to say nothing of the fact that the leak could set my 500 on fire when it decides to leak. In addition, the second tank started leaking during a race. Not good. Unfotunately, I have two pipes for the ZipTy tank. Guess I'll run these with my stock tank until I bend them.
