Reply To: Cam Timing Issue/ Valve Adjustment
What Simon said , it sounds poorly 🙁
Do you know if you can remove fairings and use your ears to find the closest area thats making noise?
Cam tensioner?
Clutch basket?
Cam shafts?
Cam chain grinding noises?
Dont rev it too hard incase something snaps as it sounds poorly 🙁
I literally just sent you parts lol.
Screw those mechanics anyway. You could learn a lot better than them and this forum has every 650 manual i could find and its uploaded in manuals section for you.
Clearances = Shims yes because Hyosung did the same thing when they helped Suzuki with their old suzuki gsx engines. I think most suzukis and Hyosungs today still use Shims. The 2020+ GV125/GV300 uses adjustable tappets (on certain models)
Tensioners = Automatic, cant be adjusted but better to safe than sorry is getting new cam tensioners anyway. That 650 is a beast that a tensioner failing can ruin a lot of parts.
I tend to replace tensioners as soon as i hear funny sounds from cam tensioner on customer bikes i work on just to be safe than sorry later.
