I just got an SV650 three weeks ago (first streetbike after coming off of 10 years of dirt). And recently there has been a ticking noise inside the engine, sounds moreso from the front cylinder but thats most likely because it is exposed. Can I adjust the cam chain tension by just screwing in the screw on the tensioners? And if they dont spring back (or at least I don't think they sprung back). Should I even try to start it. I don't want to dig a deeper hole than what I think I already might have done. Thanks-Angelo
