RE: Loud rattling noise
My T-bird has been doing that since 2000 miles. The dealer has checked the valve adj., compressiom release springs, even went into the lower end and checked rod and crank bearing clearances NOTHING! So I was told to just ride it. I have 9200 miles on it and it runs great with no problems. I did find Rotella T keeps the noise down the best. The Harleys can't hear it from waaaaaay back there.
Those that say "OLD IS SLOW" have never ridden a V65 Magna!
