    Incorrect CAM timing???

    Would an incorrectly timed cam (i.e. the chain was a tooth off) cause the ski to run lean and throw the check engine light but no fault code?

    Trying to fault find why the ski is running lean but the only thing that I left to check is the cam timing or the fuel pump. (recenltly changed cam from RR to stock)

    Thanks

    How did u time the cam?

    Lock the crank & cam & it has to be right (or at least stock).

    CE light HAS to have a code, hit the set button 5 times on an 05 model to display.

    I locked the crank and cam, apparently you can still be a tooth off on the chain though?

    The only code i'm getting that I have alway had is 1514 which is the outside temp sender, no ther fault codes (04 rxp)

    timing

    To be a tooth out and have used the locking tools you cant get the tensioner in if you put the tensioner in with the locking tools in you should be fine.
    Did it do this right from the time you did the cam or did it run good for a bit.

    Did you have the 1503 lines to the top on the sprocket?
    If possible test fuel pressure the regulator may be faulty

    It did it right from when I changed the cam, it was running really good, but lean (white plugs) and began to shut down when it got too hot/lean @ WOT.

    Def locked the cam and crank though and had the marks parallel with the head, I will re-time to make sure.

    Have their been many fuel pump failures that only occur when the under load at WOT?

    May also try the stock regulator to eliminate the rising rate.

    Check your compression, if cam timing is off it won't be at 135
