ever since reading this thread: itistheride.boards.net/thread/5197/valve-face-scale
and seeing buford's comment it got me thinking that i really need to replace the head. i did clean up the carbon when i installed my bbk but i have to say my valves didn't look much better than those pictured in that thread.
i have no idea what size valves on my atm50. can you change the length of your valves??? lets say i were to buy a head with the wrong size valves, what would i need to make it work? would i need a different rocker arm?
i just don't understand the difference between 64 and 69mm valves, other than the obvious.
