I bought my bike second hand and it didn't come with a manual .My cyclinder head bolts have come lose and .I have a torque wrench to tighten them up but i don't know what the specs are for the right amount of pressure to tighten them up at .Obviously regular sockets wont tighten them up properly to where they would sit snugg against the cyclinde and washer .Does anyone know off hand what the specs are ? Or where there's a free resource online that would tell me .I'm not interested in buying a manual i just want to know this one thing
