I've read the information concerning the valve guide seals on the 05-06 models. I purchased my RK with 3600 miles. Oil was low so I filled it up. I'm now ready for my 5000 servicing and I'm a quart low on oil. I called HD customer service and was told althought high, burning 1 qt of oil in 1400 miles is normal. Should I be concerned? Can the valve guide seals be changed without removing the heads? If so, how are the valve guide springs compressed with the heads on?
