ok i started my bike with the choke halfway open and after i saw that the rpm was about 900 i opened it all the way. a few seconds later i here a poping/tapping noise from the trans area. i let of the clutch and it died. when i started it back up it lunged froward until i let go of the clutch. i tought that maybe i had it in gear. now the neutral light will not come on. i cant find the neutral while its on. this may sound stupid but is there a place for me to check the trans fluid? is there a way to check the neutral switch?
