Hi , i do not know how many links this chain consists of , mine had seen better days , the last 7/16 chain had been bought up and cut to Triumph T160 measurements , which is unfortunately shorter than a silk chain. so i went down the route of upgrading to a 3/8 primary drive when Gasman (Crazy ) Kev did my engine , I would suggest this as the way forwards. Mr Bayliss may even have a spare kit to do it :)
Hello my friends,
...regarding primary chain tensioner;
my handbook says "tighten as resistence is felt, then loosen screw 3 full turns"
When i adjust like this, i can hear/feel, that esp. at low rpm/high load on engine situations,
that the chain is "rattling" , seems to have too much play.
shouldnt it be tighter?
Yes absolutely that was updated in the later handbooks.
It should now be tensioned with the engine running and tightened until you can hear the whining noise of the chain then back off slightly until the noise has gone.
If you tighten too much you will hear the revs drop as pressure is supplied on the chain again let off and you will hear the revs pick back up.
In general best way is to feel the tension while running you will feel the sweet spot.
