Hey guys, new here, and just here to ask a quick question and maybe some advice from you guys. So my brother just got his bike out of the shop and when he started it and let it run for a bit it was blowing white smoke. So he checked the oil and drained about half a quart out of it because it was to full! So do you think it's just because to much oil causing the white smoke and it's coming from the exhaust , or did they maybe not seal the rings right?
