I've come to the realization, maybe I'm not to own one of this fine machines. All my life, I wanted to own the infamous TRX250R. At the age of 46, my dream came true. Found a nice clean machine in Maryland. Brought her home and for a year was Happy! Happy! Then I started to purchase aftermarket cylinders, and the trouble begins. The first 330 had overheating issues. 3 pistons, until I found the water passages around the exhaust side, were tiny little slivers. Fixed that and away I go. Now comes to the current 350. Three nice heat cycles and two short little trips up and down the road, I have this galling building up already. So now we buy more pistons until I find, what the FUK happen this time? It's getting old and expensive. My 450R is a blessing! No problems like this POS. I'm on the ledge! I don't know if I'm coming back in. :upset:
