1980 B2 Rebuild

Hey all, trying to fix a few things on my new to me 1980 KZ1300 B2 which I posted about having some compression issues here . Overall my goals for this initial teardown are just get the thing running. There are a TON of super helpful posts here about maintaining this bike and I’m hoping to get in on some of the action :)I additionally got a really good deal on a Creality Otter on eBay and would like to make 3d scans of all parts I am able to. I don’t really have any experience with scanning or CAD, but this seems like a great way to get in to it. Anyone who is interested in a particular part being scanned, let me know and I’ll try to get scans out sooner for those items.
 Goals:- Full engine rebuild
   - Cam chain tensioner upgrade
   - Tensioner sprocket & roller replacement
- Water pump stuff
- Repaint with Cerakote
- Front end/seat A-series swapFuture Goals:
- EFI conversion (Megasquirt)
- Front triple/fork swap (modern stuff)
- Modern calipers/brakes ##Day 1So far I have been able to remove all of the touring related features and am looking to try converting to an A-style. Unfortunately it slipped my mind to take a before picture.After removing a handful of bolts securing the cams and cylinder head, I was hit with a strong smell of bad gas. While the coolant (neon green) and new oil I removed seemed in good condition, I’m hoping this isn’t indicative of other problems I will run into down the line. Additionally, there was a small ~3x1mm metal shard I found near cylinder 1’s exhaust valve, and a few spots that look like they were chipped. Seems like someone has definitely been in here before. So far, everything else looks to be in good condition.I’m hoping to have the block removed next time I work on this and be able to figure out what is causing the compression issues.

Looking forward to watching you build this one out.  Sounds very similar to whaat I'm doing . Start with a B and convert it to an A plus fix all the inherent issues and upgrade to current standards.Sounds like you are a builder. This is the fun stuff. Kudos !!
