83 Interstate Fork rebuild

Postby marve319 » Fri Apr 05, 2013 1:53 pm



Okay Guys, I want to thank everyone that answered back at me on how to change out the fork oil and seals. I have successfully completed the fork rebuild. I replaced the dust covers, seals, springs and some minor washers. One plastic washer under the dust cover and over the c-clip I had a friend at my job make for me. The PO defintely did not know what he was doing if he ever changed out the seals. He stripped out the bolts at the bottom of the forks and I had to drill them out and find replacements at a local hardware store. The PO also had ATF in the left fork and Fork Oil in the right one. The right fork tube was clean and the left one was all clogged up. It took close to two hours to clean all the gunk out of it. The anti-dive mechanism on the left fork was also clogged up. No wonder it didn't ride well. But anyhow after more work than it should have been, which it still was not all that hard, the front suspension is what it should be and I am happy. I now have to change the valve cover gaskets, which is not hard to do and change the oil. My question is going to be what weight of oil is recommended? I was originally told to use 20w50. Is this correct? What about synthetic oil, is it a good idea or should I stick with the regular type of oil?

Oil viscosity

You can use regular or synthetic, just make sure the oil doesn't have friction modifiers, as your clutch will not like that too much. Safest thing to do is stick to motorcycle oil, if you're not sure.

Thanks, a usual a quick response to my question. I will go with 10w30 as recommended. You mentioned go with motorcycle oil? Can you use automotive oil?
