    Rebuilt modded 250sx ticking

    Since the rebuild, I have noticed a tick the last few times I ride my 250sx. The clearances were just done. Its not horriable, but the tick is deffeniatly there. It dosen't seem to be getting any worse, but I just want to make sure i'm not doing any damage, especially to my new cam? I'm pretty sure its coming from the rocker pad. I suppose I should have listened to that person who told me to get those hard welded as well when using a hard weld cam, but anyways, any problems you think?

    Did you measure all the components in the rocker area as spec in the manual? It sounds like somthing could be worn / not adjusted to spec. Is you timing chain adjusted correctly? Good luck!

    Timing chain, good. Did the old screwdriver to the ear trick to pin point the noise, and heard a lot of noise coming from the intake rocker shaft.

    By the way, thats the most disturbing avatar I have ever seen!
