I have an 03 ktm 250 sx that tends to jump into 1st when i kick start the bike. It happens randomly when either hot or cold. If i kick start it and give it some gas, it will turn over, catch, idle for a split second then, bam. Clicks into first. I just changed to motul 10w 30 synthetic gear oil specifically for 2T. Not sure why its doing this. Any ideas???
