Oil capacity for long Roadholders

Previously wrote:

Hi Richard, I am also in the USA & have long roadholders. I converted 1/4 UK pint to 142milliliters, which is about 5oz. I have an old kitchen measuring cup in the garage (dollar store find for, you guessed it $1) and it has metric and standard graduations, works great for fork oil. I think the measurement is just a guide though. I have found it also depends on what you use for oil, the Factoryrecommendedoil, FLM auto trans fluid (what I use) or any of the great fork oils on the market with anti foaming agents.

Seems like you did it right to me. The last time I overfilled a fork leg, it blew oil past the upper seals & made an oily mess whenever I hit a bump!

Skip- Thanks for the quick reply & for confirming what I thought - I used Morris 20 w from a gallon I bought years ago for these forks - so far I've used about 10 oz. so I think my children or their children will inherit some of it - Thanks again-Richard

I think you are well within the capacity that could cause problems. I used up to180ml in long roadholders. It is as Skip writes, suck it and see. Incidentally the real viscosity of fork oils bears no relationship to the weight or descriptive term given by the manufacturer. There is a fairly comprehensive table that has all the figures somewhere on the internet.

Alan-Thanks also to you for the quick reply- I,ve been working on this total redo for over 4 years now and it's almost done - just need to rig up a temp fuel supply while the tank is at the painters, screw my courage up tight and try for a restart ! Thanks again-Richard

Hey Richard,

found this gem in a article in Real Classic Magazine:

And finally, for the bouncy bits. There's a fair bit of doubt among Norton owners when it comes to the correct amount of fork oil required for the Roadholder front end. 'Despite much confusion,' says Les 'you use exactly the same amount of oil for short, long and extra-long Roadholder forks. Use an SAE 20W, and each leg will require 150cc (five fluid ounces). The swinging arm uses EP140, and just fill up as required.'

Hi Skip- Thanks for passing that info along- I restarted the engine last weekend - all went well but I was a little anxious as this was my first ever complete rebuild. As my tank is still out at the painter's I had to rig up a temp fuel supply which was leaking here and there so I didn't run it for long- Any credit for success belongs to Mike Pemberton as he coached me via e-mail and any errors are purely mine ! I know you are here in the states, but where ? If I get it completed in time I hope to bring my ES 2 to it's first event in mid-April at the annual Gathering of the Nortons at Washington's Crossing, PA- any chance you'll be there ? Thanks again- Richard

Hi Skip- I have a 56 Dommie 99 in "large lumps" as they say that I won off e-bay a few years back - it came from Erie PA so not too far from you I suppose-anyway I'll post pictures ( if I can get my daughter to teach me how) of the ES 2 here when I get the tank on . -Richard -toolboxlbi53@comcast.net
