Honda CB750K 1976 getting a little more work completed.

I decided that whilst I have some spare time and a few parts etc I shall get into the K6 a little more and clean her up, as she has sat for so many years in a Back Garden, its only fair I revamp her a little and put her to a more Original style as to be honest, the 1976 CB750K Model was probably the best looking bike of them all and ran well.

So, I thought that I would try and clean up the lower front forks, as the factory clear coat has long gone and and as the sprinklers, hot and cold climates happen, the lower forks and anything aluminum takes a beating.

I jacked the bike up and removed the front wheel, I also made sure I used a pair of jack stands too, just to hold the chassis incase we get an earthquake here in Southern California, as 530 pounds is not so easy to pick up if its laying on the floor.

As you can see, the lower stanchions have seen better days, the pitting is caused after the clear coat gets eaten away by heat and moisture then aluminum will break down slowly in cold temperatures causing oxidization, of which you can see on the left fork lower, but I have refurbished so many of these over the years, I was not worried at all about cleaning these up to a more original look, but it does take a bit of dedication and hard work to achieve that goal, like anything else in life really.

After sanding the forks by hand, I start my process of buffing, using Block  compounds you can buy from shops, to my “Special” Secret Sauce that I have used for decades and slowly improved to get it to the standard that I like, yes its messy but that’s the reward afterwards when you see a shiny piece of art.

Its not a 5 minute process that’s for sure and the more effort you put in, the bigger the reward at the end, this is just its early stage and I increase pressure and change cutting compounds as I go along, remembering that this gets bloody Hot as you increase the pressure on the wheel.

As you can see, that is a good comparison with just a little bit of work, more to do but I am happy how this is going and people ask me how I get the finish on my Polishing, so thought I would share this with you lot today.

Yes, I wore gloves as these get super hot and being aluminum, they hold the heat for a long time, I am really happy how the forks are starting to turn out and am glad that I made the decision to pull the front forks and rebuild them.

So, a bit pf scotch pad, sanding block, then polishing will get you to this stage, I can go more but don’t want it too showy chrome looking and will rebuild these now, the upper tubes are total toast, as you can see below.

The forks at the top are always covered by the headlight ears but Honda did not take into consideration that the metal will sweat in hot and cold condition and of course rain etc can get down the forks and sit there, these forks are typical of the many that I have pulled out of the bikes over the years, so a common problem.

I believe Honda went cheaper on the chroming, using less on the forks as you don’t see it and putting money into the Motor, as I have seen hundreds like this and that’s always been the look when you drop the forks at the top. But I have a Replacement set of aftermarket ones ready to go.

I have always liked Polishing,I was taught at a old 17th century Barn when I worked for Rolls Royce as a kid and it always stuck with me and its so rewarding to turn something ugly into quite the jewel.

I use my circlip pliers to fit the snap ring into the lowers, a real life saver these are as you do not want to risk scratching the chrome by using regular pliers etc.

I try to use Genuine Honda parts where ever I can as the parts are top quality and of course guaranteed to fit perfectly, as many aftermarket parts do not.

I refitted the springs and will fill with oil when the wheel is on but still up in the air, that keeps the pressure off the springs and easier to fill the forks that way and not have the springs flying out towards your eyes if you put the bike on the ground.

So there you go, forks back on and they look so much better than before. I will be fitting New speedometer cable and New Tach and speedo gauges to clean it all up at the front, but she is taking shape and will continue to revamp her as I go along.  I will be fitting Brand New 4 into 4 exhausts to the New Honda spigots that you see in the cylinder head, also New footpegs and New kick starter and brake pedal, so keep watching and see how we go.
