Title: Strange Rattle sound (Not speedo issue) Post by tenpins99ca on 05/10/07 at 05:16:08 I have an '86 with 22000 km's (16000 miles) on it, and as of this week, when I am cruising at around 40 mph in 4th gear there is this rattle that seem to be coming out of the cylinder head. It sounds like tiny rocks hitting your car windshield at speed. And yesterday while I was rolling at 50mph the noise got really loud then it was followed by a knock which I felt in my foot pegs!! Has anyone had this problem?? |

Title: Re: Strange Rattle sound (Not speedo issue) Post by justin_o_guy on 05/10/07 at 17:17:47 I run a magnet thru the oil when I drain it. After such a racket, I would recommend you see what that shows. Also, destroy the filter, carefully, & look for metal. Make sure you keep it from pollution with dirty tools. Wouldnt want to "Find" a piece of something in the filter that came from a pair of pliers. Best of luck. Your description of symptoms is worrisome. If it was mine, the starter would turn again till I had this figured out.. |

Title: Re: Strange Rattle sound (Not speedo issue) Post by tenpins99ca on 05/11/07 at 05:29:34 I won't be starting the bike until the cam chain has been checked, and, like you said, a magnet is run through the oil. I only paid 500$ so I do not want to spen more then that on fixing her up after a grenade goes off in the motor!! |

Title: Re: Strange Rattle sound (Not speedo issue) Post by tenpins99ca on 05/15/07 at 07:03:28 OK, so I cracked her open and WOW, I was really close to having a very bad. The tensioner was completly at it's limit. I am having a piece welded onto the end of the tensioner, I'll install it today. I just have another question however, when I would start the bike (before tearing her down) there was a really nasty sound, kinda like a chain slipping on sprokets. Could this be because the cam chain was so loose? Also when I replace the clutch cover gasket, do I have to put that liquig gasket stuff on also? |

Title: Re: Strange Rattle sound (Not speedo issue) Post by verslagen1 on 05/15/07 at 08:29:01 If the clutch cover gasket doesn't have a bead of grey stuff at the top lower side of the oil channel, then you need to add one. OEM gaskets already have this. ;D |

Title: Re: Strange Rattle sound (Not speedo issue) Post by tenpins99ca on 05/16/07 at 08:42:18 Has anyone who has had a loose Cam chain, experienced a really horrible noise when staring their bike? It sounds like a chain slipping on the sprockets. Could a loose cam chaion cause this noise? What else could cause this noise? |

Title: Re: Strange Rattle sound (Not speedo issue) Post by tenpins99ca on 05/16/07 at 10:20:23 I have seen some posts about starter clutch issues in 86-87 models. I guess I 'll have to take a look at taht as well.... :-/ |

Title: Re: Strange Rattle sound (Not speedo issue) Post by Arrow on 05/16/07 at 10:22:42 You Guys got me worried now! I bought a '03 with only 5000km on it but it's got a strange metallic pinging sound when in 3rd gear. The husband says I'm "lugging" it but when I shift down to 2nd it sounds like I'm reving the piss out of her. I never ridden a Savage before and he says you've got to drive it like you hate it. But I don't want to do it any damage by over reving in 2nd gear just to keep the "ping" out of it. Anyone else had this problem or is it just my lack of experience? ;D |

Title: Re: Strange Rattle sound (Not speedo issue) Post by Savage_Rob on 05/16/07 at 10:24:29 I haven't had that problem, sorry. However, I am following your progress to learn from it. |

Title: Re: Strange Rattle sound (Not speedo issue) Post by Arrow on 05/16/07 at 11:08:19 It shouldn't be a cam chain with that low a milage on it yet, should it? |

I honestly can't offer any advice on what it might be because I can't hear the sound and I'm not imagining it well enough to have a clue as to its origin. However, I seriously doubt a bike with only 3K+ miles on it would have a cam chain failure. This assumes you're confident of the actual mileage of the engine. The only reason I say that is because a used bike may not have its original speedo/odo or, for that matter, its original engine. It's also possible that a previous owner could have disconnected the speedo for a year or two and later reconnected it. There are a number of possibilities. I am not suggesting this is the case with your bike or trying to make you paranoid; only pointing out that the possibility exists. The question is not whether I'm paranoid. Rather, am I paranoid enough? :-* |

Title: Re: Strange Rattle sound (Not speedo issue) Post by georgekathe on 05/16/07 at 11:31:21 I don't drive my savage like I hate it arrow - wonder what your husband means?(not wanting to start a fight between either of you or get myself involved in a family dispute!)sure, you should not lug it - I assume you know what that means from what you wrote but it is not a high revving bike so does not need to be screamed through the gears for maxmimum benefit - bascially you should ride it like you would any stcik shift car in my view, though will admit when I first got it was more extreme on the throttle than am now due to getting kick out of its powerful torque. has your husband been on bike & does it make same noise for him? is the noise at a given speed in 3rd - does it vanish if you go faster? does it do it in every gear. I likely wont be able to give you an answer but mayhap trying it a little bit more & giving the experts on this site a bit more info may be of more help to you. whatever - in my view it does not sound good - sorry I can't be more help here. |

Title: Re: Strange Rattle sound (Not speedo issue) Post by Arrow on 05/16/07 at 11:46:21 Thanks Guys, I think the dealerships gonna get her for a day.... Hate to do it but better that then in pieces between my legs on the road. Hate walking. The hubby rides a 800 Vulcan and isn't tolerant of my "girly bike" his words. But my girly bike can kick his fat a$$ of the line any time, never seen anything so quick. Let you know what the garage finds. Thanks again. ;) |

Title: Re: Strange Rattle sound (Not speedo issue) Post by verslagen1 on 05/16/07 at 11:55:32 Roughly, up to 10 mph, 1st up to 20 mph, 2nd up to 30 mph, 3rd up to 40 mph, 4th up to 100 mph, 5th My hats off to you if you need another gear! ;D Roughly, gear up at 3k rpm and shifting will bring you down 1k. I find at below 2k rpm, that lugging sound starts. But if you're getting a pinging sound... from the engine... is it preignition? Which can happen in any untuned engine under stress. Or elsewhere... have you checked your rubbers lately? Impulse loads from a slow turning engine may place a greater load on the rubber dampers in the rear wheel. Something I've noticed anyway. ;D |

Not that I recall but you might search using backlash as a keyword. Also set the number of days to something like 999. |

Title: Re: Strange Rattle sound (Not speedo issue) Post by Arrow on 05/16/07 at 12:15:43 Humm, I have been shifting right. Put a new plug in it but that was all for a tune up, the rubbers good. I thought it was spark knock too at frist but now.... As soon as it warms up here alittle I'll take her to the Doc, they say it might just be a vibration but she likes to do that back fire thing too that I've read about on this site. Can that burn valves? |

Title: Re: Strange Rattle sound (Not speedo issue) Post by tenpins99ca on 05/17/07 at 07:42:54 So yesterday I reinstalled my Cam Chain tension adjuster, with a new hole welded on tip (the Slavy mod), and everything works really well now. This is actually the first time I have ever done anything like this, I have never even changed my own oil before, and let me tell ya, it feels really rewarding to be able to tear open your bike, remove, fix, and replace damaged parts, reassemble your bike, and then have it start and sound really good!! I guess my next job is the "Backlash" issue!! |
