I seen somewhere that the 69 cb750-4/sohc was considered #3 bike of all time, and only 3 because it was "too boring to ride" because it ran "too smooth" and had very few problems. Thought about building a hard tail some day maybe.

I still think it was the most dependable, easiest to maintain bike I've ever owned. If I could find a mint used one I'd buy it in a second!. Those quad carbs, and straight 4 blocks produced some kickbutt accelleration, and it handled better than my current Harley! Thanks for the trip down memory lane!

Great videos Sam. Thanks.

been looking around for a 9-inch rear end disk break conversion kit. all of them seem to be around $375. I found out that if you get them, they only work with up to 6 1/4 inch axle flange, and the flange will have to be cut/ground from 7 inches for them to fit. that means 3/8 cut all around the flange and it will only leave about 1/8 inch of material outside the bolt pattern.
I checked on some Dana 44 rotors from a '78 F150 4WD and they fit around the center axle, the bolt pattern is the same, 5-5 1/2, and they can hold an axle flange up to 6 5/8 inches. That means the flange only has to be cut/ground 3/16 inch, all around, leaving 5/16 inch of material outside the bolt pattern. They are $40 each for the rotors, and that's for Duralast with thicker disk so it can be resurfaced if needed. I can make a bracket like the ones in the kits that bolt on (not welded) out of 3/16 stock, and I will need to find some calipers, maybe used with new pads. I think I can do the whole thing for around $200 or less, and with the less grinding/cutting on the axle flange, it may be safer in reguard to the strength of the axle flange. We'll find out on my next pay check (next weekend)!

I still haven't found anything for disk break kits for the front axle.
I'm working on that other front spring assembly today.
