    I am doing the first oil change after the 30-60-10 break in and noticed the drain plug threads were wraped with teflon tape
    Is this normal? or a sign of problems ahead
    Never seen this on my previous bikes

    Thanks

    I have seen it before. I would guess it depends on the mechanic - just liking torquing fastners to spec :). I do not use the tape unless the manual calls for it.

    The MOCO likes to seal the drain plugs with teflon or silicone. I change the o ring each time, and I like Napa brush on teflon made by Permatex on the threads:s

    As Smitty says, and the fact that two dissimilar metals will corrode (steel on aluminum), so the dope prevents galling or overtightening the fastener needlessly to seal.

    So should I be using something on my plugs? I torque to spec and have never experienced any leaks from any of the plugs.

    Yes, anti-sieze compound would be good and torque to the low setting that just compresses the crush washer properly (use a new one if resusing a serviced spark plug). That crush washer has saved many a head from overtorqued plugs, but the disimilar metal contact is still there, all you need is moisture and you have a small battery where metal transfer/oxidation takes place. :D

    I do use anti-seize for my spark plugs.

    For the record, my other posts were referring to the primary, oil and transmission drain plugs.

    :cheers
