SV650 loud clanking/ticking (video)
Hey guys, my when starting up my 99 SV to ride home from work it was ticking and by the time I got home it was making a horrific clanking noise, I noticed a bolt was missing where the exhaust goes into the engine, I fit a new bolt but the noise is the same, so I suspect its something inside
You can here the noise here https://youtu.be/9b5F707KLLE |

Re: SV650 loud clanking/ticking (video)
It does sound bad but could still be blow from the exhaust so Id have a good look round that area with the engine running. It could have damaged the joint and even though youve replaced the bolt its still leaking.....

Re: SV650 loud clanking/ticking (video)
I think that sounds more like a cam chain than an exhaust noise. You might be able to localise it by using a long screwdriver as a stethoscope although I've never had much luck with that. The SV automatic cam chain tensioners can stick occasionally. How many miles has the bike done?
I'll assume you haven't let the oil level go below the sight glass level or been practising your wheelies? |

Exhaust gas can sound funny when right by the head and squeezing through a narrow aperture. Anything you can wrap around the flange to see if noise changes before going off to check cam chains etc.

As for the OP, yep that doesn't sound healthy, and I've heard a few rough SV engines in my time. However things can sound a little different over the net so before declaring something terminal lets go through the process; I'd be looking at the condition of the exhaust, debris in the oil, play in the cam chain, condition of the tensioners, cam timing, big end play, etc... Any update? |

Re: SV650 loud clanking/ticking (video)
when the carbs are out of balance a lot it causes the engine to stutter as it wont tick over properly. the stutter motion of the pistons causes the cam chain to go momentarily slack and slap. i have heard it before and it has gone with a good carb balance, cam chain slack on the other hand is completely different.

Re: SV650 loud clanking/ticking (video)
Has the op looked around the exhaust - I listened to this over the video and it does sound like a blow in the exhaust more than anything.
It sounds quite tinnie - Hard to tell on a video though. |

I think Shadow Captain's bike has either gone to that race track in the sky or the problems been sorted and its cruising around smoothly again (I like to imagine its this second possibility!)
