    Fueling issues??

    Hi All,

    I've previously posted about issues I've had with my 2013 hp4 since changing the cam chain tensioner.

    So far I've had 4 new spark plugs and 1 coil replaced which was faulty. The problem is still there though, laboured up to 6000rpm and definitely not firing on all 4 cylinders proper!

    The problem only appears after 10mins riding once the bike is warmed up. I'm getting it Dyno'd on Monday but I'm supposed to be going to Spain on a bike trip next week so I'm goosed if I can't resolve this issue.

    All suggestions/experiences most welcome!

    Thanks.

    Sounds like a faulty coil pack or vacuum hose to me. Are you getting a check engine light?

    If your not getting a light check the vacuum hoses first.

    If you are I would suggest getting the ECU read before a dyno.

    One other thing, I know the O2 sensors is used in closed loop on ideal, I don't how far in the rpm range idle is bit it could also be the problem . But I would also expecte this to throw a error light.
