How to build a cool set of forks for your CB500-CB550 or CB750 Honda SOHC Motorcycle.

I get so many emails asking about certain things that I create on the bikes and parts that I build here at my place, so- I thought I would do a little Blog on my Custom Fork service that I have been doing for many years and shipping these set ups all over the Globe. So below is what they start off like, just a bog stock set of worn out, tired, telescopic front forks.

These came off a bike that was parked up many years ago and the Customer purchased the complete bike for a decent price and wanted to take the machine apart and create his own cool Custom ride, he wanted my fork service and this is a Blog on what I did.

Looks like Dogs or cats or something Hairy had been crawling across this bike for some time, also if you look, you can see the tubes are toast as there are many pits in the tubing and hard chroming these days has got so expensive to do.

The Caliper will need to be completely torn apart and I will Blog that a little later on, this is not an uncommon thing to have sent to me to fix and rebuild and hope you enjoy this little journey of what I did to get these set of forks into a really Custom looking piece.

The main goal is to take everything off, then clean up on the outside and then once happy with that, the fun begins in the transformation of these fork tubes.

There is an array of parts that I need to rebuild these and as you can see I have everything for this to fix and get the guy a really nice set up for his Motorcycle. If you look, you can see I machined the lower Fork Stanchions and put grooves in the legs for a great Custom Finished set.

Above, you can see I am about to fit brand new Honda Fork seals to the stanchions and what I personally use is some Home Depot PVC pipe that fits perfectly over the fork tube and allows me to use the tube as a Press to get the seal to slide into the recess inside the fork and not damage the rubber of the seal.

I sat the forks on a small pad and then used my Rubber Mallet and gently tapped the pvc tubing until you feel the seal come to an abrupt stop, that means its into its seating and no more tapping required.

Once the seal is in, I plop the snap ring into its place using some circlip pliers, this holds everything in snuggly and no scratches on the fork tube. You can buy these at Harbor freight Cheap.

I use Brand New genuine Honda Dampener Bolts and crush washers, I like using the real deal and not the Chinese crap that’s out there, and this will have longevity compared to China’s inferior quality.

I also fit Brand New OEM Rubber Fork Dust Caps and to really give it that Custom touch, I fit Chromed steel Dust Covers to finish off the polished Finned Lower Stanchion.

See what I mean?  It really does complete the front fork in dressing the part to show you this is no run of the mill ride, it has attention to detail.

I finish the lowers off by Polishing the clamps and adding stainless Lock washers and stainless flanged nuts, this is a great look and easy to get a wrench on to remove the front wheel at anytime.

I cleaned up the dampeners and spring and set a pre load using 4 stainless washers, an old Motorcycling Racing trick, I also do not ever use standard fork oil, I do like the old guys did and use ATF and that’s so much cheaper to purchase too.

How do I know how much to put in forks? As many of the years of the CB750 have different lengths of lower stanchions, so the volume of fluid changes.

As you can see, I have the Factory specs for the Honda CB750s right at hand and actually sell a book with all the settings in , so I can easily look up year and model to get the capacity required.

Bang on the money and now this is all ready to button up and get the forks completed for the Customer.

See, they sure do look Custom now and am happy with the way these look and the preload is right on the money too, I also use Brand new fork Caps to give the top to bottom New Parts finished look.

So there you go, a Custom rebuilt set of forks that I offer and boy do they look sharp, not cheap but add the parts up yourself, and you will see this is a good deal.

I sure hope that you liked this little Blog, thank you for following me and purchasing my parts, its my passion and Career.
