    Cam timing yet again

    So, how can the exhaust cam be pefect, yet the intake is always one tooth off either side of the mark. How can that be?

    I am pretty much done with this until someone can fix it. There is more to life than this.

    I have not messed with this yet. Have you asked Riva or R&D?

    You have to make sure you keep the tension on the chain when setting the cam position....

    Also, when you have the tensioner installed, be sure that it engages on the chain. If not, the chain would and will slip a tooth or two..

    i aint very good at jetski's but do a lotta caddy and vette motors. if one cam lines up and the other wont, then you have one of two problems. first are they the same cam sprockets(same number of teeth as suppose to be?) and if they are then you have a stretched chain or the wrong chain.

    I have asked numerous people about this and my eyeballs just are not cutting it. I have set timing on this motor over and over probably a solid 24 times and it is never right. Which means I have put everything together and taken it all apart 24 times. I don't even need the manual for sequence and torque for anything anymore. There is no way in heckll I am going to continue this just to shell out another 9 grand in parts with nothing to ride for another year.

    I bought a new cam chain to make sure it was not an issue.
    The cam shaft sprockets for the intake and exhaust are the same part number.
    I appreciate the input, just most seriously frustrated with this to put it lightly.

    This could be true also with the chain being stretched...

    R&D Cam Tensioner Tool Kit (612-92015) to observe the cam timing. As true timing is very difficult to achieve when the hydraulic timing chain tensioner does not have oil in it as the engine is not running to have oil pressure to keep the chain tight. The R&D Cam Tensioner Tool Kit utilizes mechanical spring tension to keep 65-80 pounds of pressure on the timing chain to keep the chain tight while either degree checking the cams, or verifying the cam timing position.
    Just making sure...
