R1Lou

Ive got a R1- 03 model , i suspect after checking the timing chain the adjuster is not doing its job automatic , The chain has lots of play in it , ive stripped off plastic's , tank and air box to try and get to the adjuster, It seems to be stuck right behind the chassis where i cant get to it ....i think dropping the engine out is a bit beyond me , any idea's ....anyone had to change one of these adjusters before One miserable bikeless babe !! lol
