    The new caps come with a dubious gasket that swells up with the fuel fumes.
    For new ones, just buy some Nitrile sheet (Ni70) and make one. If I remember I will go down to the workshop tomorrow and measure the thickness.

    Be careful with the choice of seal material, as the Ethanol that has been added to fuel in the last 12 months is causing some seals to swell and block the breather vents....

    Whilst we are on the subject of gas caps.. can anyone confirm the colour of a 1983 cap??.. I have read at Comontofski's site that they were black, not chrome.. I am doing a 510 4T and the cap needs replacing... I remember the caps having a vent/hose on them ..but were they black..?? I have a brochure from 1983.. but the caps in the pics are chrome.. but that may be , as Husky did, use previous years stock.. Anyone..??

    84 caps are plastic and black with a vent in the top, chrome was on the alum tanks only as far as im aware

    I agree..but I am asking about the 1983 tanks...my 510 came with a plastic tank ..a similar shape to the alloy tanks of 1981/82/83.. I am going to put an alloy tank on my 4T.. so..chrome or black..??

    alloy would be chrome....ol mate had an 83 xc with a chrome cap then another mate got a 84 a/c WR which was plastic with the big screw on plastic cap

    So.. I'm not saying that Craig is totally correct all the time..but see below..a dircet cut and paste from his website..

    How about the correct, brand new gas caps for your 67 thru 80 Husqvarna! or Maico!
    You can add a vent tube in the center and be correct for 81-82 Husqvarna.
    You can powdercoat it black and be correct for 83 (some 84).
    If you selling a used bike, why not make it look attractive to a potential buyer by fitting it with a new shiney cap.


    1 cap - $40
    2 caps - $75
    3 caps - $100
    4 caps - $120


    packaging/shipping - $10 for 1-4 caps


    Anyone else..??

    I stand corrected, just peeked in the tech ref and the xc 1983 brochures show a black cap with a vent tube on the alloy tank...go figure .. im not often right and im wrong again....:)
