| The front sprocket is retained with a splined plate with 2 bolts locating the plate to the sprocket. to remove the old sprocket remove the cover, remove clutch slave cylinder carefully! Mark the rear hub eccentric with tippex etc and loosen chain fully by rotating rear hub to give maximum play in the chain, remove 2 bolts holding locking plate to sprocket, twist locking plate in the groove its in and pull off the splines, hook chain off sprocket, remove sprocket.
You may have to take the chain off the rear sprocket first to get enough room to pull the front sprocket off.
Then fit the new sprocket, refit the locking plate and I suggest loctite for the 2 bolts and when back together reset the chain adjustment making sure the eccentric in aproximately the same place as it was before you slackended the chain,(it will upset the handling if you get the eccentic in the wrong place!!)
