On my 09 FLHR 96", NO compression releases and nothing from the factory in wiring I Know Of... I have a set of (08) heads done by Dewey's Heads up in Wa.. Blueprinted and ready to go with installed Manual PR valves. I will use them when I go 103"...
I DO already have the Higher compression using the SE255 cams. The intake valve closes at 25* and the stock HD cams close at 30*..
The SE255's put me at 205#+ up in Wa. state where checked at 700 feet above sea level and Way Low at 175/180 at 4400 feet here in SE Az.
Darn bike runs ssooooo good right now, it is hard to tear into it... Just got off my B.Day ride... 1300 miles two up and All went fine.
Had the Gen4 set at 14.0 cruise (yellow) and got 45/46 mpg and not running lean. No Babying the bike with it loaded and two up and in the Hills.:s
I know what you mean Hoop, when the motor is heat sunk and having to start..Especially YOU at sea-level... I am recently having an occasional Klankk-hick-up when starting from very HOT.. Not often enought to warrant the PR valves NOW on the 96 but it WOULD eleviate the startinng issue...
MOST of my starting is just, Hit button and Blam, it is started.
I personally Don't want auto PR valves... Many do.
I think ONLY the newer bikes MAY have the wiring BUT, I doubt IF they are drilled and ready for PRvalves. JMO
Just my take on things.
