1985 Suzuki Intruder VS750 Engine Knock

[Offshoremetal]

HI guys , I bought this motorcycle 2 Years ago and it had always had this knocking noise. It gets better when its hot but it is always present. The bike's idle also goes up when the bike gets warm. I am including a video of the bike running cold from last year after the winter ( I live in QC , Canada ) So it had not ran for 6 months. The bike is not in the greatest shape but its not that bad. Paid 700$ CAD for it and its my first motorcycle.



When the bike is warm it actually runs well, does not bog down and sounds great exept from that knocking noise wich you can also hear a bit here.




I am planning to give it a bit of love before the begining of the season with my mechanic friend but any advices / tricks would be very appreciated.

Thanks to you all and Ride Safe !

Could be a lot of things quite frankly...timing chain stretch beyond the tensioners' reach, a worn clutch basket, bad wrist pins, etc...too difficult to tell from a windy YouTube video...try to pinpoint the noise with a stethoscope or join a forum specific to that model.

Did you ever figure this out? I have an 86 that has the same exact knock to the T.

It seems that many people had the same issue with this 86.bloxd io I also had the same problem after buying an 86. Did you find the solution?
