Spent quite some time reading very usefull posts here but need your help as could not get straight answers to my doubts. Its time for a full overhauling on my 07 X, valves are gone. Otherwise things are fine but will replace cam chain, rod and piston just in case. - Would like to purchase all parts from a single supplier. Any directions? - Which brand/type of valves should i be looking for? SS? Ti? - What about piston / rod? Prox? Many thanks in advance for your assistance as would like to put my beauty back together very soon.
