I am rebuilding a set of Roadholders which are on my T110 / Slimline Featherbed Triton. As far as I can see they are unmarked. They have internal springs, not the exposed ones that I see in many photos. How do I tell which set of forks I have (long or short?) and how much oil do I fill them with? What is the preferred oil for these forks?
Remove the springs, collapse the forks and set oil level at 6 inches from top of tube. Start with 20 weight fork oil from Silkolene or whatever your local shop carries. These are starting values only. If too stiff first remove 1/2 inch of oil, no more than 1 inch to soften. Or try 15 weight at full value. Use reverse for soft but do not increase oil level more than 1/2 inch to avoid hydraulic lock and seal blow out. Hope this helps.

Many thanks for the information. I took the forks apart last night to find that one spring was 3 inches longer than the other! New fork springs required... What do I buy? Are there progressive springs for these forks? And how do I tell which forks I have? Long or short Roadholders?

Look like short roadholders to me (same as on my triton see photo triton cafe forum)external springs fit into those chrome cups & up against triple tree. Length of my forks from stanction top nut to centre of axle 720mm when assembled with springs in.

If others need to identify unmarked Roadholder forks you can measure the stanchions and match them to the information.
Swan - I appreciate your advice about the wrong tools. I have a set of 'wrenches' but didn't want to take them out of the wrapping as they seemed so shiney and nice. You advise against using a 'crescent wrench', which one is the crescent wrench? The long, spring-shaped thing? When I took my'wrenches' out of their wrapping one end was bigger than the other - which end do I use? I do value your experience.

Eric - I agree. But I also agree with Swan, the right tool for the right job is important. I posted my snarky reply when drunk and now regret it. Swan's comment was well-intentioned but I felt I was being preached at. I may not know the length of my stanchions but I know how to use a spanner. The shifting spanner was in the photo because I had used it to hold a stubborn spacer in the forks. Moral: drink less beer before posting. Sorry Swan.

Jake, Your forks are definatly short roadholders. The fork tube (stansion) length is one way to tell (although they can be made to any length you want ie: choppers )but several sure fire ways to know just by looking are 1) long roadholders use external springs, short use internal springs 2) at the top of the fork end (slider)the long roadholder uses 2 small screws to hold the bottom cover directly to the slider, the short use a main tube lock ring that is threadred into the slider , then the bottom cover threads onto the main tube lock ring. The lock ring is chrome plated and has a series of holes on its diameter to accept a pin-spanner. Now you can tell from a mile away you definatly have a set of short roadholders!You can get any part for the shorts (Norvil is who I use), the long roadholders are very difficult to get parts for.Eric & I know this all too well as he is restoring a 19s & I am restoring a model 77 which both use the long roadholders!
