Hi, I could do with some advice, help or divine inspiration. I have an 03 busa and have recently noticed that when the bike is on its centre stand & I select 1st gear (engine off) there is a lot of backlash when I move the rear wheel, The backlash is on the gear box side of the engine sprocket and is aprox moving through 1/4 of a turn. I have checked & adjusted the backlash adjuster as per manual but no difference. Is this normal & have I just become paranoid after discovering it or is it more sinister & needs delving into deeper. Your thoughts, any thoughts would be much appreciated. ???
