I don't know I had a mouse eat through a wire and it did some of those things at low rpms it was good except it would backfire on start up sometimes lay into it and then all hell broke loose change the wires but the hanging rpms got me a little it might be the video though |

Replace your engine temp sensor. I had the same problem. |

I know, more things to check, but it sounds exactly like mine did with a massive intake leak. Ran like crap at anything below 3000 RPMs then it perked up and ran fine. Good luck and let us know what you find. |

well, found out what it was.....spark plug got smashed (again). changed them out and changed the wires, and ended up taking it to the dealership to get a diagnostic and they said that if it's smashing plugs, it needs to be taken apart.
So, I left her there, got an estimate on how much it will cost to change the valves, piston, rings, and get a good tune up, and hopefully in about a week or so and $1,400 she will be going strong again.
I figure if there is THAT much play in the piston to go up and HIT the plug, there is something there that needs help. And me not having all the specialty tools and know-how like them, $1,400 isn't a bad trade off the have them take care of it. Not to mention those guys a Bigg's are top-notch. Straight forward, smart, and extremely friendly. 2 thumbs up on their service for Buellers, not to mention a lot of the salesguys there love buell to death and wants EVERYONE to test ride on. I feel at home there, so if your in the SoCal area, Bigg's H-D/Buell in San Marcos is a place to go |

Help me out here. Can there be that much vertical play in a piston? |

I'm hoping to find out what is wrong with her when i get her back. I'll make sure to keep you guys informed on it so you can have a future reference when someone comes around saying "my bike runs like shat cause my spark plug keeps getting smashed." |

No I smell a con job Junior GET THAT BIKE BACK that can not happen the bike would be a gonner and sound like an overheated deisal engine or there would be no compression the pistons would be holed or cracked you got a fouled plug if the plugs are smashed then someone put in the wrong plugs |

i put the plugs in myself, and its the plugs that buell says to put in it. I made 100% sure everything was how it's suppose to be. |

Assuming that you don't regularly operate in the 8-9k Rpm range, I know of only 2 things that will cause a 'smashed' plug in an unmodified engine w/the correct plugs:
1. Something is/was in the combustion chamber that shouldn't be there. A piece of a valve or piston, chunk of valve guide, bits of throttle plate or screws, ect.
2. The bearings in the crankshaft are coming apart, or have already done so. Either the big end of the rod bearings or the main bearings on the crankshaft at the crankcase.
I guess the piston pin bushings are a possibility also. None of which are good choices. Personally, I would want (very strongly) to be present when the top end came off. |

I would love to be there when it does come off, but unfortunately, i'll be at work, and the next time that i will be able to see her is this saturday....
It sucks, but i trust those guys at Bigg's, they are really good guys |

The piston does not have to hit the plug to "smash" it....severe detonation can easily break the ceramic...but it would be pinging horribly to do that... |

FAST I would guess that the "bucket of bolts" sound was severe detonation. |

well, by smashed, i mean that the spark plug is intact, but there is ZERO gap so no spark is there.
On the other hand, found out what is wrong with it. Got a call from the dealership today and they said that it was worse than they thought it would be and more work needs done to it. All in all it needs a new cylinder, new head, new piston, new valves, and new rings. Total now is $1,600.
Ended up heading there today to drop off a check to pay for the parts and most of the labor and right when i walked in, Dan just looked at me and said, "this way." Took me to my bike which was up on the jack, engine rolled forward with the entire front cylinder off (only thing sticking out was the connecting rod. Took me over to the work bench and this is what i saw.
And that's only the piston, they didnt let me bring the cylinder or the head home yet. But as you can see, there is a CHUNK of piston missing. You cant see it that well, but there are dents and deep scratches all over the top of it too. The inside of the head doesnt look any better. deep dents all over. I was supprised that the bike even started after that. The rings did their job though, no oil got into the chamber, and none of the debris got into the casing.
so, Brumbear, from these pictures do you still think its a scam? I sure don't....didn't from the start, i trust those guys.
Well, when i go back in about 2 weeks to pick her up good as new, i'll make sure to grab the cylinder and the head and get some pictures for you guys to see the full extent of the damage, and i'll use my buddies actual camera so it takes really nice, sharp pictures. |

NOPE you got a square deal but thats an issue you might want to send to the factory that really shoulnd't happen sorry I was just trying to make sure ya didn't get screwed |

That is quite unusual I don't understand why the piston is in such good shape and how are the valves and head also the piece should still be in the exhaustI know the bike is not under warrenty but you should call hd or buell and see if they will look at that cause that doesn't look like heat or wear it looks like a bad casting maybe they can do you a solid on parts I'd try man |

The piston is missing a piece at the valve indent.
Maybe that valve was hanging open, striking the piston. |

yeah but the valves or at least 1 should be bent fer and if they are not chewed up and the head is ok then the piston should have a million little dents in it or a few big ones NO ? |

I wd. think the Cylinder as well wd. be Scored and marked...I think if it was me I wd. buy a whole new used low mile engine of Flea BAy and sell what ya can of this one.. they go on Flea bay anywheres from 1200.00 to 1800.00
Plus whats the chance that junk never got circulated
throughout the oil, Wdn`t take much...Just my .02 cents... |

I don't think Buell will cover that, since the muffler was gutted. I think the muffler probably contributed to the break(over-rev, over heat?). Guess the broken piece killed the plug, cylinder wall, head, etc... I wonder if he was able to remove the piece, replace the plug, if it would have ran???
Just more Blather...

It did run after i replaced the plug, had to get it to the dealership. Went at least 40 miles in that condition.
Shows that even though some parts may be weak, the engine in whole is a strong piece of work. |

Okay, that explains a lot.
Hard to troubleshoot since most bikes don't run after this but I have seen it before.
Is your bike still under warranty? Here's the warranty argument. If the valve indent is too sharp, there can be a heat buildup concentrating on the sharp edge. It melts, failure, and the rest of the piston breaks down with it.
The factory is supposed to round off the edge (you should too, on aftermarket pistons). |

UPDATE!!!
Got a call from the dealership today saying that they got all the parts in and were about to start putting it back together. But there is a catch.
They were saying that they were doing some checks on other parts before they put the new parts and and finish her up when they found out that the flywheel was loose. Not sure what that means, but they said the best thing to do was to replace it. I asked about how it will affect it if i let it stay, and their expert guy there said that it will be ok unless i starting hearing a lot of noises coming from the engine. Since i don't have the extra $1,100 right now to have that done, i told them to just put it back together and call me when it's done so i can get it.
Here is my question to everyone out there (especially for those that work at dealerships).
How much does a new flywheel cost to buy, and how hard is it to change it myself if i had a good source for tools. I already have a service manual, but it doesn't really have much on specifically the flywheel and how to replace it. So some help with that would be nice too. If it's not too much of a hassle, and will take a good day of tinkering with it at a shop, then i'm down to do it myself, but if i need a bunch of specialty tools and all that other good stuff, then i might just have to take it back in there sometime in the future and have them take it apart again and do more work on it.
Thanks for reading this, and the help so far. |
