Rocket fork seals

I recommend you clean the stanchion with some silicone spray before storage this winter. That cut in the rubber could be insect damage at speed. As long as the stanchion is not pitted or rusted the seals should last a number of years. Debris is the most likely cause of premature seal failure.

I was thinking when the bike is taking off the road later in the year of lowering the dust cover and cleaning around the lower fork and putting something like AC50 or rubber assembly grease in and around then working the fork seals over the winter months. Both stanchions are perfect and the seal that failed was not split but a faint mark as if something passed in either direction up or down. I drained the oil over night and the oil that came out was fairly clean except for the last drags which you would expect from normal wear and tear over the last 2 years also the fact I put new progressive springs at the time in which would have shed some debris.

when rebuilding transmissions i visually check the seals for nicks, cuts or if it has a spring then while putting a lightweight grease i feel the seal for any thing that does not feel correct. i once installed a seal on an old buick without the spring and the fluid just poured out.
