Reassembling the bottom end. Here’s where all those pics I took while disassembly come in real handy. The hardest part was applying sealant to the seams and getting the case closed before it harded. I also installed heavy duty cylinder studs. Reassembling the bottom end. Here’s where all those pics I took while disassembly come in real handy.

Case painted and ready for reassembly. After a run through the dishwasher, I gave it a good wipe down with acetone, before primer and paint. Case painted and ready for reassembly.

Washed the case in the dishwasher to remove any soda residue and oil before painting. Do this while your wife is NOT home!

Split the bottom end. Everything is in pretty good shape, so no replacements. Also a couple of detail pics I took for mental notes. One showing where a dowel goes (aligns the case when assembling) and the last shows what order the bearing shells go in. It’s very important that they go back in the same order. Split the bottom end.

QuestionHey, Nice build! Tomorrow im picking up a 1979 CB750 my self .1st, from what my friend told me is to pick up a SOHC over the DOHC. Why? 2nd where should I relocate my wires and such? I wont be buying a banana seats because my lady will be riding me for the most part. 3rd, do you have a facebook so i can follow your build? i dont go on here much. thank you in advance. Again, great build and keep it coming. Answer

Hi, thanks! From what I’ve heard the SOHC are a little easier to work on since there is more documentation online. Might also be easier to get parts for, but I know a lot of people customize the DOHC’s and they are faster so I wouldn’t worry about it. As far as your wiring goes, it just all depends on what you want to do with the bike. Also make sure you take a ton if pics when taking anything apart. This has saved me several times.

Some of the cylinder studs decided to be giant butt-holes and not come out. I tried heat, rust penetrator - all to no avail. I ended up welding a nut right down next to the base and that did the trick.  Some of the cylinder studs decided to be giant butt-holes and not come out.

P.S. take a butt-load of pictures when taking things apart.

Top end is off. Keep those rocker arms and shaft collars in the right order! I put mine on this lid and them covered it with foil and taped it up to keep them in place. After I removed the pistons, I checked them in the bore and found out I will need new ones. Top end is off. Keep those rocker arms and shaft collars in the right order!

Oil tank turned out pretty damn good if I do say so myself. For those wondering if my welding skills suddenly improved - no, a friend welded it up for me.
