Hey everyone I need help with my 1997 Honda trx300ex. It's been sitting for over a year. I bought it used and not running. It didn't have a starter on it or a battery or an airbox. I've bought those and installed them. I also changed the oil and filter. It basically had almost no oil in it when I got it. I have it running now and when I start it, it smokes a lot, white smoke. It's definitely burning oil. I'm wondering what it could be. I'm thinking its oil in the head, but why is it there? Should I let it run for a while and see if it just burns off? What to do next?
