Forums 🚥 PiT STOP 🔧 Hyosung Technical Help Cam Timing Issue/ Valve Adjustment Reply To: Cam Timing Issue/ Valve Adjustment
If the tensioner came out , it means you will have to remove the stator casing or clutch basket (depends which cylinder you touched) and check the chain did not fall out of the teeth at the bottom of the crank
Then use the manual as if you were installing a cam chain again , and setting up new camshafts again
While the cam shafts are removed , check under the tappets for shim sizes currently on the bike = Eg. Rear cylinder might have 125 and 145 for intake and 200 210 for exhaust , so keep those in mind….
Put everything back together properly and follow the manual until you are safely able to spin the crank a feel times by “hand” to make sure the timings are good.
if the timings are good, then follow the manual again, to find valve clearances.
Eg. If 1x shim is saying 0.35mm on exhaust but the manual says you need 0.20-0.30 clearance. You have a 21o shim. You will buy a 200 or 205 shim to reduce the clearance from 0.35 in to maybe 0.29 healthy. The manual will explain further but hopefully i made sense ?
