The front bearing was shot after 3 gallons, I've never had that problem, so I got my old p5 out, 8 gallons, and compared the bearings and they are not the same as the old ones. Are the new bearings cheaper or did I just land off a huge jump, really possible, haha. Anyway Is this common for a faily new engine to need bearings, not OS hehe...I put tko ceramics in it and they felt a bit tight so I fired it up and it loosened after about half a tank, cool, those ceramics do improve the engine performance, I had to see it to believe it. Can't wait to race it. I guess with the ammount of racing I've been doing I can expect things to have issues, no big deal, but I am suprised a bit. and yes I run gen2 25%. I might add a bit of oil to the mix just to be sure. Oh yeah, is it ok to leave both shields on the front bearing???
