04 xb12r -- cranks fine but very noticeable bobbling hard banging sound in engine as if a cylinder is clanking around -- not sure the problem -- started after I high rpm shifted a couple times --
there is a tiny tiny hole in the front of the exhaust (that I plan to Fix) could that cause it
Also can that hole be fixed with Weld Epoxy?
thanks |

Maybe your primary chain adjuster gave up,or maybe you hammered the mains or the wrist pins out. Lacking any other information i would start with pulling the primary. Beware your redline,these long stroke engines have high piston speeds. I can't see any way a VERY SMALL hole could cause this. Also,consider the extreme heat involved when choosing the epoxy for your exhaust, maybe somebody with a wire feed could fill it for you. Good luck. |

Thanks is it possible to do just using the service manuel or should I let a shop do the work, I only have a basic knowledge and no garage to work in. |

also if its a piston problem do I have to drop the engine to inspect it! or can I open her up and look inside |

Using the service manual anyone should be able to check for excessive primary chain slop, when it comes to opening her up, basic knowledge is not enough. How would you know what you were looking at? By the way, were these downshifts? |
