I've gone and installed a new chain kit on my 07 GSXR 600, and upon attaching the sprocket cover, I've noticed now the clutch pushrod won't depress, engaging (ahem, disengaging) the clutch. I've tried going through the gears, briefly starting it up, but it still refuses to budge. The only thing I can think of is that I did start it briefly without the clutch pushrod in, leaking some oil, and thats gone and done...something. But I've heard people doing this without dramas before, admittedly on other bikes, so I didn't think it was a big deal. Ideas?
