To install and adjust you manual cam chain tensioner: Remove valve coverf and observe factory cam timing, yu may want to use a shop manual to verify proper timing marks at this time. Mark the timing dots, lines, whatever, I don't know at this time with correction fluid for easy reference.Mark the crank and case markings as well. this will dispell confusion. now remove the factory tensioner. Now set the reach of the new tensioner so that you are just barely able to bottom the base of the tension against the block, Dont tighten the locknut yet, just snug it for now. Now recheck your cam timing and make sure that no timing change has occured. Now install the tensioner bolts and torque to factory specs. Check timing again. Pull on your crank wrench and observe any slop in chain. If all is well, crank the engine and observe any clicking or ratcheting sounds, if so lightly tighten the tensioner bolt until sound becomes inaudible. Let engine fully warm up.Now slowly loosen tensioner up until you hear a faint ratcheting sound. Tighten back up once more until sound disappears. Now from this point is where tuners might disagree as to what the tensioner should be moved or not. I say to run the tensioner another 1/8 turn and tighten lock nut. When you hear faint ratcheting return later, time to adjust. I used this method for 6 years on my mid 8 second 81 Suzuki 1260 drag bike with cam motion G3 cams and never had a single cam or valve train related problem. Put over 3000 passes on this bike. Need I say more.
