    Valve clearances

    Just wondering if anyone can point me to the correct part of the manual / procedure + clearances at TDC. Been looking through the manual, but I only seem to be able to find complete engine disassembly instructions rather than just checking in situ.

    Cheers,

    Andy

    Much appreciated bud. Next question is do the clearances transfer over to the 2000 Mille R? I know they're the same V990 engine, but with them changing to big valves on later models just wondering if the spec listed on that site is still correct for mine?

    I have just done the valve clearance check on my 2002 Mille and there was some interest on a guide on the PB forum so here it is.

    Remove seat.



    Unbolt tank and lift up.





    Note: To make access easier it is best to cut a piece of wood to hold the tank up as high as possible rather than the prop that comes with the bike.

    Remove the air box lid.
    Remove air filter.
    Remove crankcase breather from bottom of air box.
    Remove vacuum sensor from bottom of air box.
    Remove air box lower half from throttle bodies .


    To make it easier to get the cam covers off it is best to remove the throttle bodies (2 x jubilee clips) and move them over to the left out of the way.

    Note: place a rag over the frame spar to prevent scratching and put rags in the inlet rubbers to prevent anything falling into the engine inlets.



    It is now possible to remove the cam covers. I done the rear cylinder first.

    Note: clean any dirt and grime off the covers and surrounding areas before removing the covers to prevent getting grit or dirt inside the engine.

    The cover bolts are quite hard to get to so a combination of tools are required. I had to use a small ratchet to get to some and extension bar and universal joint/wobble bar to get to others.

    Rear lid off



    Make sure the cam lobes are not pressing on the buckets. the position of the cams shown below is perfect for checking clearances.

    Note: the way I turned the engine over to get the cams in the right position was to put the bike in top gear (6th) and with the wheel off the ground on the paddock stand I turned the back wheel forwards until the cams where in the right position. It is hard to turn over but if you remove the spark plugs it will be easier (need to change them for the service anyway).



    Check each clearance in turn and write them down as you go.









    Do the same for the front cylinder.

    Note: the engine will have to be turned over tot he correct position for checking the valves. see technique above.

    There is one bolt that is hard to see and get to, extension bars and a universal joint are required unless you want to take a radiator off which I did not!

    You can see the bolt if you remove the left fairing panel and radiator fan (just above header pipe).



    Lid off



    Check as before.
    The only tricky one is the exhaust valve under the cover, this requires a little more patience but is not too much bother.

    Make sure you note down all the settings and keep as a record.



    Before putting it all back together it makes sense to 'tack' the valve cover rubber gaskets in place to the lid with a little instant gasket silicon.
    There is no need to cover the whole lid just tack it in the corners to stop it falling off while you re-fit the lids onto the engine.

    Note: on the front cylinder there is a sensor wire entering at the back left of the head, make sure the old sealant is cleaned off before re-assembly and that you apply some instant gasket silicon across this wires rubber seal to prevent any possible oil leak.

    Sorry to thread jack, but will these be the correct valve clearances for an 07 RSV 1000? I haven't been able to find this info anywhere...

    Thanks

    Good guide.. my first insight into v twin clearance checking. Don't suppose you have a link to a 2002 service manual?

    anybody who has tried this valve clearance procedure, did you have to adjust the clearances at all? how much difference was it? could you feel the adjustments afterwards?

    You probably wouldn't notice the difference but would prevent damage to your engine in the future.. unless they were so tight it would not start or so loose the engine sounded like a bag of bolts..

    I have read that some people go up to 40k miles without needing to adjust after checking every 9k miles or so.

    Mine unfortunately requires almost all of the shims to be replaced.. I haven't managed to get the cams out safely yet so all I have done so far is measure clearances.

    Whats the quick release seat mod you have?
