its a tranny problem, expensive problem,

 

mine ended up costing me about 1700 i bought black diamond valves and the l&a 1 way and new gear and new cam chain and they had to fabricate a cam chain guide becuase mine broke but also at the same time i had them replace my clutch to a reldine clutch.. it was pricey the L&A one way itself is only 250 with teh gear so its alot better to get it done before it breaks alongwith other things..
