Ok. this problem has been happening more often now a days. I dont know what it is. When am riding and i come to a stop sometimes. white smoke stars to come from under the bike. somewhere from the header and it smells like burnt oil. now i have notice that it happens more when the EXUP valve gets stock (code 18) and i think that it might be exhaust gasses are trapped and are trying to come out tru some other place. but i dont know. any input will be very appreciated.
