Bridgestone Project: Exhaust and Heads Part II

So on to the second part of the tear down of the exhaust on the Bridgestone Dual Twin.  I have a couple videos to post, and pls keep in mind that I don’t have a ‘camera crew’ or an film editor (but I have download Adobe’s software to try — at some point– to edit my videos), nope just me and my Android.

So I showed last post how the exhaust was attached.  Not much different than most other motorcycles, except for the rubber pieces that connects the header to the baffle.

You can see the header is a bit rusted but the bolts came off with no problem. The first header I removed was the left side and there was little to no room for a wrench much less be able to get a socket in there.  So it was a bit more clearance if I were to remove the head.  Which I’ve been meaning to do to get a look at the piston and cylinder so I did. Here are the pics and the videos:

This just shows the bolt on the inside (between) the left and right exhaust.

As you can see here's no room go get a socket or even wrench in between the frame and back nut on the header.

So taking the left head off was going to gave me more room.

The heads are on with for nuts on studs in the head.  These looked really rusted but it came off easily.

Here are couple of images:

Of course I have to include a shot of the pistons and cylinders and you see them in the videos as well.
