I’ve got a ultra 250 2007 model with 70 hours on it.
It has taken water into the engine block and has mixed with the oil.(Milky looking)
I assumed it was a cracked head but had it machined and pressure tested.Was also told it had dropped a valve.Had it all repaired with new seals etc and put back together.When I took it out for the first time after getting it back it lost power at high revs for about 5 seconds and regained power almost immediately.It did this 3-4 times at high reveal then stopped doing it.After about 10 minutes of easy riding I checked the engine oil again and it was mixed with water again .Any ideas as to why ???
