Started into this project today. Looks like the recent blowout only added to years of oily gunk in there. One benefit to having the frame caked in an oily mess is no rust. Tank off, fairing off, air box off, breather hose off. Here's what it looks like:
Other end has similar, if slightly smaller cracks. I was expecting bigger. What kind of pressure does this hose carry?
One thing of interest (to me), the hose was installed upside down (i.e., as shown in the photo). As a result, the hose was pressed against the farthest aft fin of the voltage regulator. I suspected there might be a hole at that spot, but looks like just a bit of an indentation there.
Tomorrow begins deep cleaning.
