I've noticed lately my bike has difficulty shifting between gears. when going from 5th to 2nd gear really quickly, the bike tends to only shift down to third, then i have to really play to get the bike into second. Once the bike was stuck in 1st gear and wouldn't shift. I had to stop the bike, pull in the clutch and rock the bike back and forth while pulling up on the lever to get it to hop into neutral. Then I was able to shift between the gears again. I wasn't sure if this is a common occurance with a 2005 rm250, but if this happens while racing, its sure going to mess with my lap times.
