hey guys, after setting my valve clearances perfectly yesterday from advice, i went for a test ride up my road today and after about 5 minutes my motor made a click noise and cut out. i pulled off the valve caps and the end of the arm that moves the valves had snapped : O and was sitting in the cap( the end with the nut and stuff that you adjust). i think because the motor revs pretty high and i bought the cheapest replacement head i could find cause of other problems and it wasnt up for the high revs. The question i've got is how to replace this arm as i've got a spare from the old head that are still good and i figure would be upgraded as theyre not broken. pics would be much appreciated as i dont know all the proper names for engine parts. thanks
