    Excellent video! Great spreadsheet too - have been looking for exactly this procedure, and it pops up by another Aussie! Thanks again!

    I just did my 08 450 at 282 h. EX was 0.21mm IN was 0.15mm. The engine has only just started making tappet noise but only when cold.
    Didnt need shims because I just reinserted the old shims upsidedown so the wear patterns didnt match up.
    The rocker arms were now rubbing on the valve stem indentations. This took up some of the excess clearance.
    Then I also reinserted the rocker shafts upside down or spun them 180 degrees on their own axis because they were also worn but as Scott said only on the bottom half. Spinning the rocker shafts gave the rockers a brand new unworn surface to run on and again took up some more excess clearance.
    Close inspection of the shaft design tells you they are symetric so they will work upside down and not have any oil flow problems.
    Clearance afterwards was EX 0.15mm and IN 0.10mm . Waiting till a 4 stroke starts to make noise before adjusting valves means you only have to do it once in its lifetime.

      So i can just take out the shim and put it upside down with the weared up spot on the bottom ?

    Thanks for this video. At 3:24 you mentioned to get the engine to TDC. In the subtitles you write that you want to be sure the engine is on the compression stroke. How do I know if the engine is at that point?

    • @ScottElliott152
      @ScottElliott152  4 роки тому +1

      Thanks Neil. On the compression stroke both valves will be closed. As you turn the motor watch the valves ... you should feel free play on the rockers after the valves have closed and the piston is coming up towards TDC compressing the air/fuel. If you put a screwdriver into the spark plug hole it will move up and down with the piston which will help visualise what's going on.

    Hi, I've been following your video step by step, thanks a lot.
    I have a problem adjusting the valves: when I torqu15 Nm the rocket arms after calibrate the valves gap the rocket arms get blocked and close completely the valve gap, any idea about what's I'm doing wrong?

      Did you check the torque on the pivot bolts first? See 3:28 in the video.

    Thank you Scott! I have a 2008 KTM 450xcf, this should be the same procedure correct? And a quick side question, my bike likes to get hot really fast upon startup and spits coolant, within a minute of starting it up. Do you have any recommendations?

    • @ScottElliott152
      @ScottElliott152  4 роки тому

      Sounds like a head gasket leak if it's spitting coolant from the exhaust.

    • @colestadtmiller5280
      @colestadtmiller5280 4 роки тому

      Scott Elliott My bad, I meant to say it spits coolant out of the overflow not from the exhaust, I just don’t know why it gets warmed up extremely hot really fast

      @@colestadtmiller5280 hopefully it's something simple like the radiator cap has failed. Replace that first and see how it goes. And yes valve clearance adjustment process will be the same.

    Great info, thanks for sharing. Not sure if I want to attempt this myself though. Question: the valve shim kit - are they generic for any bike? I thought the sizes (radius) would be different?

    • @ScottElliott152
      @ScottElliott152  5 років тому +2

      Thanks Luke.
      The shims are pretty well standardised into small and large diameter. The motorcycle manufacturers don't make their own shims they outsource and I'd guess there's probably only a handful of companies who make shims for this application. It seems the Japanese bikes use the same diameter ... well I've worked on many different makes and models of sports bikes and they were all the same. The shim diameter used on the KTM is the same as my CBR600RR, GSXR750 and a friends R6! I'm pretty sure Ducati's use a larger diameter of ... I think 7.48mm.

    I have an ordinary 2005 Vito
    I changed her oil
    Wind filter
