Might of spelled that wrong. My 05 fatboy was bored out from 88 to 95 this past winter and I,ve had nothing but problems since. At 1125 miles after the work was done the engine begin spewing oil out of the breather tubes. The mechanic changed rocker box gaskets,umbrella valves, lowered the operating oil level, Checked the pressure relief valve on the cam plate, oil pump alighnment all seem to be working properly according to him. He finally decided that he needed to tear the top end back down and he told me that he found the rear cylinder gald. What would cause this? I broke it in just like he told me -60/65 the first 500 miles and 70/75 the next 500 miles. Like i said it was about 1125 miles when the problem started. I did start running alittle faster knowing the 1000 mile break in mark had been met. It seems like excessive pressure slowly builds til it pushes it out the breather tubes. Do,es anybody have any suggestions. I,m getting ready to head for South Dakota next week.
