    BBR klx110 top end rattle.

    I just got a new BBR full mod klx110, there is a rattle, not a quite one. I'm almost positive it's coming from the top end, should i be worried? if so what should i do?

    Thanks..

    P.S bore kit is the 143cc by TB with racing head.

    Race heads make noise, it's the valves is all, completely normal. I was worried too at first when my engine made a rattle/tick sound but got over it. Make sure your valves are at the correct last and your cam chain isn't sloppy. Is it coming from the head?

    Valves get louder as the RPMs increase. Do you have access to a camera to snag a video? It's incredibly hard to diagnose from here.

    I do, but at the moment my clutch is taken apart, would be together but i broke the right engine cover gasket. once its all together i will start it up and video it.

    Sounds like its about to blow up! Sell your bike to me for super cheap

    But seriously, valve noise is different than a rattle. If I were you, and I had any doubts, I would tear that engine completely down, grab my mic or calipers, and measure every little piece.

    dont tear it down unless your going to rebuild it.. if its a ticking sound thats loud and you have a v2 head you have nothing to worry about thats just the sound they make..
