My Yamaha TTR 90 dirtbike will not shift into 3rd gear until I've rode it for 5-10 minutes.?

Question

Also, sometimes when I let off of the throttle, it makes a chirping sound as it slows down. What's wrong with my bike??

Answer 1

Any fluid on the outside of your bike other than mud? Check your tranmission fluid. Should be a dipstick on the tranny case on the right side of the bike. It's usually black and screws in above your right foot but I'm not positive on the TTRs.  Make sure that is at the correct level.  It's a good starting point, But if it's really low you could have some serious damage to the transmission. Good luck
