My wife and I were having a discussion on snowmobiles. I have recently completely rebuilt my rear suspension, cleaned and rebuilt powervalves, new clutch, polished sled from top to bottom, replaced worn track clips...and so on. She said "now your sled is all ready and needs nothing more right?" I told here a "sled is never complete" IE: new skis, clutch kit, new more agressive track, reed pack, and so on. Can anyone help me explain to her why us men are never happy with "GOOD ENOUGH" or "FAST ENOUGH".
