2010 Royal Enfield Bullet 500 - 1982 Honda CB125s
Hi to all,
I have a CB125s and recently while riding I noticed a lot of noise coming from the head and determined that the cam chain might be a bit loose causing the sound. I know the valves are alright as those were tightened to spec recently.
I have a Clymer manual and it specifically indicates that there is a different procedure for the 1970s CB125s and for the 1976 onwards CB125s.
The pre 76 ones can be adjusted cold, you just remove the plastic cover from the bolt, remove the top plug bolt and then loosen then re-tighten the adjustment bolt. However for the 76+ models it asks that you turn on the bike, let it get warm, get to idle at 1300 and then do the adjustment while the engine runs and to not remove the plug bolt completely as oil will spurt out.
Here's the problem : The 1982 CB125S does not have a tachometer and so the manual says you should use a portable tach to set it to 1300 idle.
I am trying to figure out if I can adjust the cam chain exactly as done in this video:

I want to avoid buying a portable tach (they seem to be 100-125 dollars for wireless ones that sense the pulse from the coil) to do this adjustment...
I figure it should be possible if done like in the video but I don't want to make the situation worse....
Thanks for reading.
