Step 1: Loosen the 2 bolts of swing arm and loosen chain fully with the chain adjustment tool
Step 2: Remove the small plastic front sprocket cover
Step 3: Remove Clutch Slave Cylinder
Step 4: Remove Gear change control lever and connecting rod and let them hang down from the gear shift lever end
Step 5: Remove Left side rear frame
Step 6: Loosen 2 bolts holding the front sprocket
Step 7: Swivel and remove the sprocket retainer plate
Step 8: Slide out the sprocket with chain
While refitting, make sure you apply some medium strength loctite solution to the 2 bolts before you screwn in the retainer plate and sprocket
Also, make sure you tighten the other bolts, including the swing arm one with a torque wrench set at the right values
Hope this post helps somebody. I struggled to get help from any forum to change the front sprocket.
