The front-most frame bolt was nagging me so I figured now is as good a time as any to get it in. It was kind of funny because when that bolt was in there the front-right forward frame bolts would not go in. Pat said to get the jack and use the tapered metal rods to move the frame into position after loosening the bolts on the engine, too. After playing around with the jack and then more importantly the tapered rods, everything just lined up all of a sudden it was really super. After getting all those bolts torqued down I went back to the carburetors.



Last week I had left them in half-installed state with the carbs seated but not mounted on the air box side. Staring at the shrouds I realized that it was wrong, I should have connected them to the carburetors first before installing them for two reasons. The first was that there is physically no way to position them on the carb, so it has to be wrong. The second reason is that it is also nearly impossible to pull the shrouds out of the airbox at that point, too. This time I mounted them and then kind of squashed them to get the rack down into the assembly, both time actually because I installed the 1 and 4 shrouds 180 degrees off!






That did work, but I forgot to loosen the airbox so the shrouds wouldn’t seat nicely into the airbox. So, I loosened it and they still did not want to seat properly. I tried just about every push pull and twist I could and they just didn’t want to seat. That wrapped up the night, next time I will see maybe I can move the airbox more and just play with it until everything fits.

Reassembly continues along with lessons learned.

• Shifter rubber install: As you can see it doesn’t look like it would fit, that is, until you boil the rubber in hot water!
  
• Drive sprocket cover install: Without incident.
  
  
• New kickstand rubber: Pried the old one out. New one slipped right in with a little grease.
  
• Began front frame bolt install: The holes didn’t line up so I disconnected the front right frame, put a jack under it and raised it, which made the bottom hole line up but made the front right frame hole not line up. This is a work in progress; also need to check the chain slack after I get these bolts back in.
  
  
  
1. Began carburetor installation: This was interesting; the service manual is strangely not-detailed here. For me it wasn’t a race and I made mistakes but was OK about it and took my time backing out mistakes until it made sense. What I did seemed to work well so far, but we will see because I didn’t finish.
2. What I did was to first hookup the throttle and choke cables because there is no way to do it easily when the carbs are in the bike; I used a plastic sharpie to hold the throttle open so I could more easily reach the “pulling” throttle cable mount. Before hooking up the cables, I shoved the air intake shrowds inside the air box leaving their mount points to the carb intake exposed. You can see that they are designed for this once you try it; you will also notice there is probably no other way to get them installed has you left them off when you installed the carb bodies.
3. I only slid the carb bodies 1/2 way in so that I could hook up the cables and sat on a stool nearby so they could rest on my knee. The choke worked just fine but the throttle was way too tight, Pat explained that it can be loosened up at the throttle itself; I had no clue what that thing was before he told me! Vio helped me out and made the adjustment for me; it helps here to have a buddy around to help. To give you some perspective on having the carb rack 1/2 the way in, once you have it hooked up, you can move it around because the cables are at the right length; this helps for installation.
4. The next challenge is sliding the entire carb rack through the empty space because it is difficult to mount the carbs in the cylinder head side exhaust rubber and also the engine air intake tubes are in the way. For the rubber, I very lightly lubed it with some grease, on the air intake side also. For the air tubes, I disconnected the T-connector on the top so I could move the tubes around. I knew that they sit between the 1-2 and the 3-4 carburetors, so before and during sliding the carb rack in, I lined up those intake tubes so they would be in the right place at the right time. If you don’t do this, you end up pulling them apart and or moving them into the wrong position, and even better their metal clips fly off leaving you wondering whether they fell into your cylinders or heavens knows where (I found it lol). With the carburetors in place, you can stand over the bike and guide/force them into the exhaust rubbers and using some force they just seat themselves. That wrapped up my evening, I will be back at it soon.
   
   
   
   
   
   

Got a few things done tonight all it won’t look it.Here is my work list:

Tonight I had high hopes of achieving completion of many tasks despite lots of evidence that I could not work that quickly.
Continue reading “CB750F: Day 29: More Reassembly”

A lot of work and preparation and parts-shipments seem to have come together in perfect timing to allow for a lot of reassembly work to begin. As usual how things when was mostly a matter of preparation in reading the service manual and talking to Pat and having some patience while doing the work and trying to use my brain and think through things before and while doing them. That said, it is totally OK to take a break and go for a walk if things get not-simple. Here is the work list:

Tonight was very “out of the flow” kind of night.
