Okay so spoke to soon. Well not really :P Looks like after 3 1/2 gallons and the bearings are a bit gritty. No biggie. So going to replace them. Thinking of going with the TKO ceramics. Any feedback on these would be great. Also being as the Incredible Hulk put in the head screws they are a bit stripped from getting them out. Does anyone know the size of these four bolts as I don't really want to buy the complete screw kit for just these.
