Hello

Im new on this forum but i really need some help. i bought an honda cbr1000rr from 07 it has 32k km on it. The dude before me crashed it hard. I'm almost done fixing the bike. I only have 2 problems left.
1. The bike wont go in gear. When i first got it it could go into every gear perfect. I started working on it and suddenly i got only go up to 3 gear then it fot stuck. Now its stuck in neutral. I replaced the clutch checked the master and slave cylinder.
2. The speedometer goes up when i rev. (I think i got a bad ground. Pls confirm)
Here is a video of me trying to go in first or second gear. Hope somebody can help me and thank you.
