Her second gear is worn out, I have been shifting through it for years now.

I will open the engine up, mesude and see what needs to be done.  Project for this and maybe next winter.

Won a '76 motorcycle license plate from my state that I will be able to use in lieu of a collector plate (40 years old) next year on my 550K2. Or... maybe I'll opt for a special letter plate. What are popular special letter plates used on our SOHC 4's?

Spent the day yesterday and an hour today completing the framing and HVAC of my basement. Couldn't stand it any longer so I went out to the garage to play. More gathering, fitting, cleaning, etc. Slow but sure progress. Working on mocking up the front end and seeing what I need to order while waiting on the 78 F rear parts. I have MOST of what I need for the front but can't find my fork caps and the dreaded right control has the plastic box for the starter button broken. I need to break down the caliper and see what's inside and kit it. Also need to find ONE headlight stay bolt. Fits these models:

 CB400F A MOTORCYCLE, JPN, VIN# CB400F-1000006 TO CB400F-1038492 

 CB400F A (76) MOTORCYCLE, JPN, VIN# CB400F-2000001 TO CB400F-2008280 

 CB400F A (77) MOTORCYCLE, JPN, VIN# CB400F-2100001 TO CB400F-2104166 

 CB500T A MOTORCYCLE, JPN, VIN# CB500T-1000001 

 CB500T A (76) MOTORCYCLE, JPN, VIN# CB500T-2000001 

 CB550F A MOTORCYCLE, JPN, VIN# CB550F-1109886 

 CB550F A (76) MOTORCYCLE, JPN, VIN# CB550F-2000003 TO CB550F-2010866 

 CB550F A (77) MOTORCYCLE, JPN, VIN# CB550F-2100001 TO CB550F-2114871 

 CB550K A (77) MOTORCYCLE, JPN, VIN# CB550K-2000007 TO CB550K-2015308 

 CB550K A (78) MOTORCYCLE, JPN, VIN# CB550K-2100001 TO CB550K-2122082 

 CB750A A (76) MOTORCYCLE, JPN, VIN# CB750A-7000001 TO CB750A-7007331 

 CB750F A MOTORCYCLE, JPN, VIN# CB750F-1000002 TO CB750F-1015054 

 CB750F A (76) MOTORCYCLE, JPN, VIN# CB750F-2000003 TO CB750F-2022317 

 CB750F A (77) MOTORCYCLE, JPN, VIN# CB750F-2100011 TO CB750F-2111489

To finish my day I did a model shoot trying to decide what color I'm going with. You can see a little progress after going blue.

I did this last weekend! 4-4 test drive.
Changed my avatar today. From the old look from 1984 to latest look last weekend.
New CB750 OEM mirrors in the process. I have a new OEM seat in a box in my garage... ;)

I have a funny feeling the throats on mine are too long... my airbox tilts backwards. Or maybe my intake boots are too long.

Anyone have a comparison shot of aftermarket vs. original intake rubbers?

Which ones? Airbox to carb, or carb to head?

I noticed that the aftermarket carb to head intake rubbers seemed to increase in length from left to right on my 78K to the point that I had to extend the airbox mounting hole to the rear (in the tab on the frame) with a small grinding stone in the Dremel to allow the airbox to shift to the rear about a 1/4". Otherwise I was fighting the airbox to the point of nearly cross threading the mounting bolt.

That picture is old vs new, new ones were all the same, 750, 77 78 k or f only, fit well.
Other ones had different lengths in each set.

Installed the baffles in my No numbers 4-4 HM300 replica. Very nice to drive, so smooth and relaxing. The baffles had thick layer of fiber quilt around. I removed that when it should choke engine completely.

New OEM mirrors on too.
