Rear Shock Oil Weight

Postby prc » Sun May 20, 2012 2:47 pm



My 82 Interstate-(minus the bags,trunk and light bar) has factory shocks that have no damping action.
I found a how to article in which new seals and oil are installed in the old shocks.
Wondering what type/weight oil to use, the ever popular ATF solution or something designed for shocks.
I am leaning towards 15 w fork oil, the bike is considerably lighter than a stock Interstate, but ocassionally I will have a passenger or overnight duffle bag.
Any thoughts/experiences are welcome, thanks.

The GL1100 service manual specifies ATF (12.5 oz, or 365cc), so I think you'd be safe using either that or 15 weight fork oil.

Hi, My Old Girl 32 year old 1980 GL1100i passed its MOT this morning, after 16 plus years tucked away in a garage, in the UK they always do recomendations, mine were both front and rear offside shocks had a light seeppage. I think it is where I have just rebuilt them. I will keep an eye on them. I refilled with the recomended ATF to the recomended amounts, ther were no visible scratches or pitting on the shafts, but should I find that they are right I would like to try a thicker oil as I find the ATF quite thin is there one that I can replace it with. I am in the UK and some of the USA specs are slightly different so if you have the info a full spec just in case I have to convert to UK spec thanks :?

Best Regards

I used 15wt Bel Ray fork oil in my '82 Interstate rear shocks, it seems to be adequate.
