Just purchased an 72 CT70H from one of our members.
Will need to replace front tire and front shock seals.(to start)
Can't find how to info on either in a search of tech section.

Links to one or both and perhaps a link to an online parts and repair manual will be helpful

Thanks

I highly recommend buying a bike specific maintenance manual.

I found this in another thread.

If you're brave/careful/lucky, the lower fork leg can be used like slide hammer (as has been suggested by others) but that can get really messy. Once the lower leg has been removed, pour out any remaining oil and thoroughly clean everything. You're almost certain to find metallic particles suspended in that old, dirty, oil; all of that needs to be cleaned out. Spray solvent through the orifices at the lower end of the inner fork leg and blow it out with compressed air. Repeat the solvent cleaning until no more dirt can be seen on a clean white paper towel. This is also a good time to clean & re-polish the outside of the lowers, followed by a light application of wheel clearcoat.

Reassembly is easier and cleaner. Sart out by oiling the inner fork leg, inside surfaces of the outer, then sliding the two together. Oil the new seal and gently drive it into place & replace the C-clip. Now is a good time to replace the springs with new HD versions. Next, add the oil. If you're on the light side, use 15w, if you're much over 175lbs, use 20w...fork oil. The last step is to optimize the quantity of oil. Add an extra 5cc, then try to compress the fork leg. Repeat this (5cc oil/testing) until you reach the point where you feel the suspensionaction begin to stiffen near the bottoming-out point. That's where you stop adding oil. If you've kept track of how much additional oil you added to the first side, then you can simply add that same amount to the other and you're done...fork rebuilt and tuned. You should notice a substantial improvement in shock action and ride quality.

Here's a link to a diagram of the HK1/K1 Front Fork Parts Diagram. Once you open the link, scroll down to the bottom to see the diagram.

Congrats on the purchase. I think Hornetgod mentioned all the sites you will need to get thru your build. A Clymers manual will help tremendous. Got mine from the local Honda dealer.

See Mrdi, I told you this was the place to be! Great people!

Probably the hardest part of seal replacement will be removing the fork sliders from the fork stem. More'n likely they've been in there since Honda installed them. I've attached a couple diagrams to help. Wheel removal from owner's manual. Parts fiche to help with bolt removal. Remove wheel, remove #27 bolts. Remove fender and horn. Loosen #18 clamp bolts. Complete L&R fork assemblies can now be slid from bottom of fork and removed.
