hey there is a loud clunk when shifting into first from nuetral and i feel the bike alsmost jump not forward but idk, also it does this when downshifting into 2nd sometimes to its always done this since i got the bike is this normal or is there something worn in my transmission,
also i replaced the rear wheel bearings the other day and since then my steering feels to easy to turn, almost not as stable, i dont really hear or feel rattleing or loosnes but something doesnt feel right it could be my tires maybe, but with even a slight back and forth motion to the bars the bike swerves side to side so much more.

 

I had a similar issue. The shifter was loose on the input shaft. If you leave it too long the splines wear and no amount of tightening will cure it. I replaced my shift lever and it cured the clunk.

 

Have the clutch adjusted could be all it needs.
