Used 1972 Honda CB Used 736L

Seller Description

This is a K1 CB750 that is titled as a 1972 model. Some of the experts say the K1 models were
only made in 1970 and 1971, but my research has convinced me that some 1972 K1 models
exist and I believe this is one of these.
I am happy to pass along these details if you are interested. About $13,000.00 has been invested to get the
motorcycle in this condition. In
addition, I spent hundreds of hours on this project, but it was a labor of
love. I restore old bikes for a
hobby. A new NOS speedometer was
installed during the restoration and it currently has less than 700 miles on
it. Mike Learn who is a friend and
nationally known air brush painter did the paint job. CycleX professionally rebuilt the engine and it
has been enhanced in many ways. For
example, the alternator rotor was lightened and balanced. It was bored 1mm over and fitted with high
quality pistons, super flow valves, heavy duty valve springs, heavy duty
cylinder studs, heavy duty rods and a MLS head gasket. Gears in the transmission were undercut. A CycleX CX1 cam coupled to a heavy duty cam
chain and a cryo treated primary chain was installed. I found the list from CycleX and it is shown below. You can
see the engine is very special. The bike
has a high quality secondary “X-Ring” chain with new sprockets, new exhaust
pipes, high end coils with electronic ignition and a new seat. In addition, new wheels, spokes, fenders, tires,
handlebars and many others. A mix of NOS and reproduction parts were used
on this project. The manufacture date is
9/71. It is beautiful, but not perfect. I chipped the paint on the front left edge
and there are some scratches here and there like on the end of an exhaust
pipe. The exhaust flanges have some rust
as it was ridden lightly for about 700 miles after the restoration in late 2017.
About a quart of paint was leftover and the buyer can have it. It has been taken to one show where it
won best in class. This bike turns heads. I have a nice surprise for the person that buys this motorcycle.
----CycleX work
I believe the crankshaft was lightened and balanced but it is only listed as "balance and clean" below, so I am not sure if it was lightened. I remember discussing that, but it isn't on his list.
