  • YZF R15; Valve Clearance Adjustment!

    Valve Clearance of YZF R15 should be regularly done at an interval of 3000km.

    # Valve clearance adjustment should be made
    on a cold engine, at room temperature.
    # When the valve clearance is to bemeasured or
    adjusted, the pistonmust be at top dead center
    (TDC) on the compression stroke.

    Valve clearance (cold)
    Intake

    Exhaust


    Note: always be cautious when you pull out the Fuel lines, never use any tools. you can do it with your bare hands itself. always keep your hands clean when you deal with engine parts.

    YZF R15!


    Step
    1. Remove the Front panels of both sides by removing all the nuts marked by Red circles using Hex keys.



    Step 2. Then remove the seat cover and unscrew the 4 hex nut(red marked) using Allen keys(provided in toolkit)after removing the nuts carefully detach the tank from lower clamps!



    Step 3. Remove the Drain tube, the remove the fuel lines and power plugs underneath the tank. Always remember never use any tool for removing fuel line, if you Find any difficulty in removing those hose always feel free to ring me(00919496808074), always happy to help you!




    3> Always keep the tank slanting like this. Because if you keep it horizontally on the ground it will cause damage too fuel pump!



    3>> Keep the Fuel Lines covered with rag or a cloth to take out gas, also remove spark plug cap.



    4. Disconnect Air induction system vacuum hose and Air induction system hose (3-way joint to air
    cut-off valve)!



    5. Remove Reed valve plate by removing two 8mm nuts(Red marked) . and remove 5 nuts of TDC.



    5> For the ease of accessing the TDC lets remove it by removing 10mm nut



    6. Remove Timing mark accessing screw & Crankshaft end accessing screw (both marked in red!)



    7. Turn the crankshaft counterclockwise using 19 ring spanner to bring piston to top dead center
    (TDC) on the compression stroke.!



    8. Align the TDC mark on the magneto rotor with the stationary pointer on the magneto cover. Check that the cam lobes, if its in Compression stroke the lobs will be even.



    8. Measure Valve clearance with flier gauge with apt measurements! If the Limits are under limits put everything back, If not adjust it with Yamaha tool

    Tappet screw holder
    YSST-706
    Tappet adjusting socket
    YSST-706A




    8> Disassemble to flier gauge in order to make the measurement and adjustment handy!



    9. Before putting the TDC cover use a good silicone marker(Ana bond) as a gasket. after that everything back in reverse removal order!



    2>> Nut arrangement!



    4, 5 & 6>> Nut Arrangement!

    Note: Always keep everything neat and arranged else you will feel confused when you think about putting things back!



    1>> Left Panel screw arrangement!

    Note: Always keep everything neat and arranged else you will feel confused when you think about putting things back!



    1>> Right panel Adjustment

    Note: Always keep everything neat and arranged else you will feel confused when you think about putting things back!



    1&2>> Keep the things like this for there safety!

    Advice is a form of nostalgia.
    Dispensing it is a way of fishing the past from the disposal, wiping it off, painting over the ugly parts and recycling it for more than it's worth.

      Can you please say with reference to the pic if the crank position was right for tappet setting?

        SIr from where to buy this feeler gauge blade, i don't need the entire set
        JUST THE RIGHT ONE FOR TAPPETS & SPARK PLUG GAP(.8)

          Valve clearance (cold)
          Intake

          Exhaust
          I had rtr, the settings on rtr were
          cold>
          intake 0.07mm
          exhaust 0.11mm
          which is too damn low but I guess there is a lot of difference too between rtr and r15 .So I was a bit worried about 0.1mm and 0.2mm.

          Let me rephrase here,
          I adjusted them on looser side of spec, 0.24 and 0.14.
          It ticked a bit loud, so i tightened them to tighter side, 0.1 and 0.2.
          They still ticked, I put a long screw driver and started hearing but putting the tip on cylinder head.
          I was pretty sure it were exhaust tappets that ticking, intake was fine. (from screwdriver test)

          I know they will tend to tick a bit on idling, cold engine. But unless I ride consistently at 6k+ revs, they never go silent.
          So I decided to tighten them more, I put 0.15mm there, it didn't tick but I had cold start problems(probably compression loss)

          I finally turned the screw outwards, its around 0.17mm now, no ticking at all.
          I guess that is the correct needed clearance, as joel (The race concepts genius) mentioned to put 0.1 mm on exhaust on the other thread too.

          So my question is if anyone has adjusted their spec to 0.2mm exhaust, does it tick or is it just me?
          Hows the response?
          Cold starts or anything?

          Personally I have found 0.1mm and 0.17mm best settings, I checked compression after high rev riding to be 62PSI which is greater than 55PSI as mentioned in manual so no valve sticking out too. Compression is fine ,no cold starts and spark plug runs on glossy side indicating a good combustion.
          What you guys prefer?

            Can we buy tapped adjust tools from yamaha service centre?
            Svc at my place donot use these tools.
            I had to buy thickness gause by myself.

              nope, the svc wont sell these parts.
              all you need is the tappet holder in the pic below with the 8 - 9 ring spanner or normal spanner

              I too am running the .2 mm on exhaust. and it does tick noticably upto 6 rpm. but i adjusted to this setting as mine was not idling correctly.
              the idle is good now, no cold starting issues either and the bike has done 5300+ kms, it doesnot sound right though, will adjust again at 6000 kms.
              will try the .1 on exhaust. but i cant digest .1mm on both intake and exhaust ?

                Let me put it in a nutshell.
                1 mm exhaust can be a problem, I say push it to 0.17mm where it won't tick. Whatever you do, don't go intake less than 0.1mm or else there will be starting issue and some ,ore here and there. Inlet i would say better off with 0.1-0.12 range.
                Optimum range for me ( been using it for a while, say 2000kms now)
                intake 0.1-0.12mm
                exhaust 0.17-0.2mm

                  Thanks for replying . bike has done 6k today, i'll be servicing her soon, definitly before next week.
                  the engine is smooth now, but its just that tick that gets to my nerves.
                  will go with .17 on exhaust this time
                  cheers

                    Today I adjust the tappets gap without using any guage. Adjust these with shaving blade. As shaving blade are having thickness of 0.1 mm(as measure it with screw guage). Exuast valve are set ~0.15 with some looseness of thickness of blade. Intake valves are set ~0.1 with tightly of thickness of blade.

                    Now after the above service process , took a short ride .
                    Bike showing some hesitation@5k rpm.
                    Some clicking sound when I accelerate the bike and leave the throttle at neutral. Only in cold engine. No sound at hot.

                    When I close the hole of silencer with some cloth and accelerate there is no sound except clutch bell's minor sound of thud thud @ idle.

                    Sometimes bike don't start in first click of starter. needs 2nd click. Sjould I check electric starter or tappet gap may be the reason behind it.

                      Hai. Sorry for very late reply. I have been running on factory said clearance since last 50 k km(Post free service era). There is no ticking on bike by setting on that rpm till date.
