cant get to first gear, all other gears work
So I was at a stop light today and down shifted to first, or so I thought. Once I got the green light I tried to go and realized I was in neutral. I tried down shifting to first like 15I times and to no avail, then I decided to roll the bike while down shifting and got it in gear before the people behind me got pissed. After that I was fine with all my gears except first still doesn't want to get into gear. It gets out of gear just doesn't want to get into gear without a major fight. Any ideas as to what this could be?
