Re: Starter chain on CB77

I found out that the starter clutch was loose on the rotor. Tightened it up and the major noise is gone. With the current setup I assume 219.60 chain is the correct one. Chain needs to be tightened with 0.5 mm shims to get a realistic slack. One starter motor has probably some incorrect parts instal...

Re: Starter chain on CB77

Starter chain on CB77

Hi I am fairly new to vintage 4-stroke bikes. My first is a CB77. The starter has a terrible noise. Sounds like the chain sprocket is skipping inside the chain. The current chain is a 219.60 chain. I can see it is too slack. Have approx 2cm slack. Saw that the manuals and the chains for sale are 219...
