1981 GS1100E Engine noise

[Cwoods]

Ok, I finally got the flywheel puller in the mail and just popped off the flywheel and assembly. I look at this as a victory, I bought the bike from the previous owner who parked it many years ago at his first notice of bottom end noise. I'm very confident this is the culprit of all that gnarly bottom end noise I heard at idle.
As I figured the one bolt was snapped off and the other two where backed almost all the way out. The one that's broken in the flywheel is a tad rough but if I can draw it out of there it looks like it is still good to use after chasing the threads to make sure they are clean at the start of the hole. I expected to find more damage behind there than I did, so again to me its a victory and I'm happy.
What's some suggestions of the best way to get that broken bolt out? I'm hoping it wont be too rough to extract....I'll start to tackle it tomorrow. Also have to try to find bolt replacements of the correct grade, and yes there will be red locktite involved! A good day!!

Got the broken off bolt out after a bit of effort, a couple 3/32" drill bits and a broken easy out. Metal was very slightly peened over the start of the threads so I easily cleaned up the threads with a tap and cleaned all the parts as well as inspecting close for damage. All is good just need 3 new bolts in the 10.8 grade suggested here. I have a feeling that will be an issue finding here in Anchorage but I'm going to try our local Fire and Fastner specialty nut and bolt house tomorrow.
