Hi all, Yesterday I had one of our local Yamaha dealers fit new WR450F gearing into my YZ450F for trails. All seems well except for one small thing I've picked up. Lets say I'm at standstill and have the bike idling in gear with the clutch engaged, the bike stands still........no creep, no problem. If I kill the engine, still holding the clutch in and push the bike forward, the bike feels easy to push for a second (like neutral), then it's as if the gears mesh and you can feel the bike gets more difficult to push. If you then stop pushing forward and pull the bike backwards, it feels exactly the same, runs free for a second then becomes more difficult to pull. It feels like there's a lot of "backlash" in the gears. This in itself is not a problem, but, before I had the Transmission changed, the bike felt heavy to push from the beginning in both directions, not this "backlash". Could someone please let me know if I should be worried and get the bike back to the dealer or is this normal WR transmission behaviour.
