I picked up an 04 500 Ranger with a bad motor. I put a motor in it that I had ran before and didn’t smoke. I got everything on it today and running. Motor is running good and strong. At idle no smoke at all. I let it sit 5-10 minutes with no smoke. When I start riding it and get on it it smokes like crazy, blowing oil all over the tire and everywhere. The vent tube seems to be fine. Unless I’ve got it over filled with oil I’m not sure whats going on. The fact it doesn’t smoke at idle or low throttle then smokes so heavily when on it harder has me confused. Any thoughts on what could be going on would be appreciated. Thanks
