That might be a little over the top - I think the APE stuff is generally very good. Yes - you can break an APE valve spring but look what you're asking it to do: You have a very limited space (the same length and diameter as stock) in which to now accomodate much higher valve lift. Then there's always the chance of coil bind if you don't set the head up right, and the more seat pressure you run, the shorter the longevity of your valve job. A friend of mine broke a spring on his KZ, but he was running .425 lift cams on the street for two years, literally touring all over the country. The stock intake cam only lifts .318 or so, and the exhaust about .300. Look at the PS bikes - 1-3 passes on valve springs for the 2-valvers is all they get, lifting over .600". As usual, just my $0.02.
