What's the deal with removing the carby on a 03 wr450? Looking at checking the valve clearances for the first time. The owners manual states that the carby should be removed first before you remove the cylinder head cover but after studying the bike itself I really can't see the carby being in the way. Is there something I am missing? What does everyone else do? I would really like to be prepared before I attempt this for the first time. Also are there any Aussies who could recommend a shim kit available in Melbourne or should I just ask at the Yamaha shop?
