My Crf150r locked up the other day. I was riding in my neighborhood and when I went to the end and turned around in like mid 1st. I went to take off and it shut off and the kick start lockup. I tried push starting it but it's all locked up. Then I put it in 1st and pulled it backwards and I hers a little puff and I tried to kick it and I kicked once and locked up again. There's oil and stuff in it. HELP Please!!!
