put on over 800 miles the first day, average speed 75mph by the gps speedometer about 80, hot hot hot.oil consumption low. maybe 5 oz after 1400 miles .Florida was smoking hot on the turnpike.got backed up in the toll booth... no problems but when I was leaving the toll booth i had some large metallic raps .... like it was ready to throw a push rod or a lifter was coming apart. it was 106 outside I thought oh oh looks like i am going to be walking... but it kept running.....I think it was some serous pinging going on.I notice some small pinging from hard accelerating now that it didn't have before.But has been running and starting fine.I may check the primary chain adjustment before I start back to Chicago.so far so good!!!!!
