Changing head pipes
I have seen several threads about guys having head pipe bolts break while trying to remove them. I know exhaust bolts can be a pain on anything. Any tricks to it that may eliminate a problem? Is it best to do it cold or warm the bike up or any other things that may make it easier? Thanks.

cold - use aerokroil penetrating oil - and put studs in when you have the bolts out...
ps your 2010 should already have studs - nuts come off pretty easily - torque to 9-10 ft lbs when you reinstall...

I'm having a bear of a time getting the front cylinder to seal with Dresser Duals on my 12 RG Ultra. I have tried everything I know to do, even double gasketed last night. It was actually worse than ever. I'm not sure what I'm doing wrong, or if the bend on the pipes are just off. Not sure at this point. I am going to try again tonight or tomorrow night if I find the time. I did go with aftermarket flanges and retainers. I'm wondering if the thicker flanges are causing the issue. Just can't get the pipe to sit in there snug and square. It's always off enough to cause issues.

I've changed the head pipes on several bikes, this is my first Harley, and it seemingly defies logic as to why it will not seat properly. Really weird. Problem is exacerbated by the problem being the front cylinder. LORD JESUS they made that area some difficult to get tools into. Getting a torque wrench onto the inboard nut is an exercise in patience.
