Valve adjuster screw damage and replacement

Discussion in 'The Garage' started by Mitch81special, May 2, 2021 at 6:15 PM.

  1. Hi everybody,
    I been trying to find the source of some top end noise and when I was setting my valves (.06mm intake, .15mm exhaust) I noticed some damage to one adjuster screw. Someone told me its possible to put the screw in a drill and polish it back with sandpaper? I think this ones too far gone as iv read that the hard layer on these is very thin. I know I can get a replacement from Mike's but I seen a few posts here about them being soft and poor quality. Anywhere else I might look? other than ebay.

    I'd like to hear more on the Virago adjuster replacement, their Allen head top looks an improvement over the little square.

    The adjuster screw is part # 3HT-12159-R0-00. All of the usual on-line parts houses have it (Partzilla, etc.) new, OEM, and I'm sure you can find it on eBay. Your local dealer can order it too.
    Here's a good set of on-line parts diagrams:

    Here's a pic of how they look in an XS650 - they're a bit shorter than OEM ones

  8. Maybe I should give the Virago screws a go. Were do guys source them? Partzilla or ebay I guess?

    I ordered 2 pairs of these.

    Spendy, but no need for any material removal on the rockers, as is the case with the Porsche/ VW elephant foot adjusters. Most likely lighter as well. I just assume that XT/ SR500 cams, rockers and valve springs are at least as tough on the adjustment screws as any XS650 will be.
    Time will tell.

    I have the Kedo adjusters in my XS and my SR. They got my vote :)

    those Kedo ones are I I believe called a flat ball set screws, or something like that, you’d probably find that McMaster Carr or someone sells them at more reasonable prices.
