Though I did learn that the break-in period for the suspension components is only 200 miles (can pull the page number from the owner's manual if anyone is curious). Needless to say my all time high so far is 0.80 G's - really wanting to max out the display but that might have to wait until I'm past 1,500.
...Sort of surprised....Thought you would have drained the oil and put in 30wt first thing....then stomp on it and seat those
