    RPM going up and down, please help!


    I having issues with my RXT-X aS RS 2011. When doing full throttle from zero, rpmīs going well up to 6000-7000rpmīs, but then it fall 1000rpmīs and then up, and down and up and then reaching top RPM. Then it goes well. This dont happen all the time, let say 50%. I have changed to new SC and at the same time added Riva Power filter kit. Have change ignition coils too. A few times it drops rpms in lower speed and in top speed too.

    I really be glad for some advise what I can do, this is really enoying to dont know what to do.

    Thank you!
