Hi guys, I'm not sure if this is a problem or not but my gearbox makes a clunk sound when dropping gears. If I'm in 6th gear and pull the clutch in then start dropping gears there is a definite clunk sound as each gear engages. The gears go in ok and I have no trouble getting into gear going up or down. I have also tried doing clutchless up shifting but can't get the gears to budge up but if i give the gear shift a swift firm push down it will down shift without the clutch. Probably has nothing to do with the clunck sound but thought I'ld mention it. The bike is a FZX250 zeal.
