Hey guys! So I took my wheeler for a ride today. I got about ten miles from home and stopped to light a smoke and man oh man was there a ticking coming from the head. It sounded more like it was from the intake side but it's impossible to really tell. . It has the correct amount of oil in it. I check before every long ride. So I'm home now and I just checked the valve spacing and it's spot on so I know that isn't it. Any ideas on what it could be? There is oil in the head but not as much as i remember from the other times i checked the valves. Oil pump maybe? Is there a way to check that?I just changed to full synthetic and It's been running great. Thanks.
