I have a P5 XLT with 1 gallon through it. It was broken correctly and I am running a turbo #5 in it. It ran great all though break in and ran great though its first race weekend but then I started to have issues. I believe I have a air leak somewhere because at times it will run strong but all of a sudden it will bog and flame out. I have replaced the fuel tank and fuel lines and I also have replaced the exhaust gaskets. Is it possible that the front bearing has gone bad? There is a little moisture around the bearing but nothing crazy. I went ahead a bought a #17011 bearing to replace it with. Are there any other things I could check? Like I said its a almost new motor and ran great up until this past weekend. Any help would be great. Thanks
