nah its not valve tap, ive heard that before. Its a lot louder then that, my friend describes it as dry metal on metal hitting/knocking/rubbing sound..haha but yea im almost positive its not that, its way to loud for it.
Initially i thought it was a sticky lifter but it would only do it while it was warm. Now its just a loud knock right from a cold start even after its warmed up
since i had about 900-1000 saved up for a mountain bike which im no longer getting due to this knock...with that 900 for budget could i basically rebuild the internals? like new cams/pistons all that stuff...im not to familiar with internals, my friend however is a mechanic and has no problem doing this stuff.
