How many times can I seize an express?

So I have seized the xxpress three times so far with only one ring. The piston and cylinder were a little rough but i didnt feel like replacing the whole piston last time I had it apart so I just put the top ring on and called it good. The reeds in this thing are all fucked up. the stick closed and the bike gets crazy vapor lock and over heats a lot. I have a set of boysien reeds but the reed block is stripped on this stupid little bike. I will fix it soon enough. this bike takes a lot of abuse. I have put 3,000 miles on it this summer and it still runs good when the rings arent broken. It revs out to like 10k its insane. its one of the best bikes I have ever had. Its also one of tje stupidest.
