A test you can do now is pour a little rubbing alcohol (or spray carb cleaner) into the ports and see if the valves hold it. If not, you can lap the valves sometime this winter and have them ready for Spring.

I wasn't planning on just dropping them on when the time came. I'll probably take them up to a shop just for warranty purposes and pay the 50 or $80 to just have them looked at. if they need to do a couple things for another fifty bucks or something I'm not going to get bent out but if they're talkin they need to put a few hundred dollars into them then I'm sending them back.... The paperwork says that they have to be checked out before you use them... Thye do come with a one-year warranty... Not living and dying on that but doing my part..
