Title: Seized engine? Post by DesertRat on 09/28/16 at 11:52:27 long time no talk ... Stopped for gas and hit freeway, was riding home and she just shutoff. Battery checked - OKAY Wiring connections - OKAY Right cover pulled - Timing chain and cam tensioner - OKAY Left side inspection cover, socket rotates motor - OKAY (not sure how much pressure is req'd to spin motor, easy/light pressure or forceful/heavy?) Is my engine seized? How do I check? |

Title: Re: Seized engine? Post by justin_o_guy2 on 09/28/16 at 11:57:24 socket rotates motor It's not seized Now. If it seized it stopped turning over. Should've made the tire slide. Should've made noise,like metal grabbing metal. If you just lost power and rolled to a stop, plenty of stuff can do that. |

seized means frozen, does not rotate. So when she shutoff... did you skid to a stop? or at least skided till you pulled in the clutch? |

Title: Re: Seized engine? Post by justin_o_guy2 on 09/28/16 at 12:21:09 Before you pull the plug, clean out the cavity it sits in. Take a spare plug, hook it to the plug wire, ground it, and check spark While the starter motor is working, making compression. Check battery voltage WHILE the starter is working. Grow a pair Of arms, out of your chest, you're gonna need them. A Tink Could be a spark plug breaking... I've never seen it happen,, Any direction you think the sound came from? It bothers me that sometimes it turns over and sometimes it doesn't. Any clattering as it coasted down? Does it feel like it's got compression when you turn it over by hand? If you can push it in first gear, that's not good. |

Title: Re: Seized engine? Post by verslagen1 on 09/28/16 at 13:04:44 I'd grab a volt meter and see what v's you have sitting idle and while starting. less than 10v it won't start. as long as it sounds normal, you can try and start it. I had a bearing cage go on the counterballancer. most of the time it sounded normal. every once in a while it'd screech for a few seconds. then the cage failed completely and it made a lot of noise. screeching, clanging and banging. |

Title: Re: Seized engine? Post by justin_o_guy2 on 09/28/16 at 13:15:47 I'd get a hot battery on it, I'd have ether handy. And if the exhaust messed up and clogged up, it's not gonna run good, Haven't seen that ever, except on catalytic converters, gathering rust across, but they don't make a Tink Noise. Without the plug it Should be spinning great. . |

Title: Re: Seized engine? Post by Dave on 09/28/16 at 13:25:38 When you turn the engine over by hand (left side crank with a socket and breaker bar) - do you feel the engine come up on the compression stroke (gets harder to turn), then suddenly it goes over top dead center and wants to unload the compression and you have to hold it back a bit? (This confirms the engine has compression, and that the cam and valves are operating properly). |

Title: Re: Seized engine? Post by hotprops on 09/28/16 at 13:41:09 wonder if the gas was diesel not put in the correct tank .do the old sniff test |

Good point, maybe bad gas, drain and replace. May run fine. |

Title: Re: Seized engine? Post by justin_o_guy2 on 09/28/16 at 14:05:02 Easy test, possible answer,, |

Title: Re: Seized engine? Post by justin_o_guy2 on 09/28/16 at 16:15:53 Bad results without voltages doesn't tell us anything. Unless you're charging the battery, you're just gonna run it down |

Title: Re: Seized engine? Post by gizzo on 09/28/16 at 17:15:32 using a 12v truck battery wont do any harm. |

Title: Re: Seized engine? Post by norm92de on 09/28/16 at 17:15:41 In aviation we kill a few people a year with miss-fueling accidents. Not the likely cause in your case however. |

Title: Re: Seized engine? Post by norm92de on 09/28/16 at 17:19:47 Any 12v battery will be ok. The only change is the amps which don't make any difference. In your case I don't suspect the battery. It must be something else. |

Title: Re: Seized engine? Post by norm92de on 09/28/16 at 17:23:27 I have seen Die-Easy batteries go open circuit but in very case the car continued to run until it was shut off. |
|
Title: Re: Seized engine? Post by norm92de on 09/28/16 at 17:43:46 DesertRat, I don't think a bad battery can do much until you shut down. Maybe somebody else can chime in. But the alternator should keep the voltage up and keep the engine running. |

Title: Re: Seized engine? Post by raydawg on 09/28/16 at 17:48:45 Just a friggin guess.... Check the groundings, like the kickstand circuit, etc |

Motorcycle batteries are crap and can die suddenly. I had a plate fail that shut down my bike like a switch. |

Title: Re: Seized engine? Post by Kris01 on 09/28/16 at 18:49:03 Leave the battery in the truck to make life a little easier. Hook up your jumper cables but DO NOT start the truck! If the truck battery starts to run down (after cranking the bike for a while), unhook the bike and let the truck's alternator charge the truck's battery for a few minutes. You do not want the truck's alternator putting juice into the bike! |
