dsbike The neighbors gave me a 54 shop manuel they got with a 54 they bought new. It is kinda oily but in good shape. I don,t know of anything newer than that. I suppose they had shop manuels for task force too. Used my 54 book for brake work on my 51 6400 plus that older one. Best info I got was from Jim Carter live on using hydraulic jack oil from your local FLAPS to service the boosters. It will lube that big leather cup and make the booster make it's special happy noise when working. Mine will slide the tires if you climb on it. I havn't seen a reason to do much else to it. ABS system doesn't exist for those does it ?? Anti lock breaking system.
