during my 103 high compression build, i felt it was good insurance to get the manual compression releases. i'm glad i went that route, and it's no hassle at all. i didn't use the automatic ones because they're a lot more work to get to if you need to service them. with the manual compression releases, they're no more work to remove than a spark plug.

awesome, sounds like i'll go for manual releases. just going to 10.2 cr not very high but some times my glide has a hard time crankin when hot with the stock cr so figured this will be good insurance. Also looking to install a woods torque cam, intake valve closing earlier raises cranking compression and low speed compression to boost low end torque. this makes cranking harder too. most high duration cams aren't affected as much as the intake valve will close later. If it seemed manual releases were too much of a pain was gonna go with the S&S ez start cams, but looks like i'll be good to go with a woods 7hg7 cams

look at this dyno run, 103 with rhinehart true duals with s&s 585 cams to a 106 with D&D fat cat and woods 7hg7 cams

Started with stock 09 Ultra 96ci and after I changed to a 106 I went through a couple of starter clutches and eventually had eletric compression releases installed, only a month or so now, but so far so good.

My biggest problem is thinking I can start without pushing them in, which is usually the case on a cold motor. A hot motor....I grind the starter and the bike still will not start unless its in neutral. I now have automatics and highly recommend them, very easy starting.
