...took the K2 for a ride and after it I stroed it in the barn for the winter time.
Sad times…. I’ve been hoping for “one more” but might have to give up.
I also had hopes for a ride a week ago. The weather app showed +9*C and sunny for the Saturday earlier that week.
That changed to colder and rain.
I had planned to ride my 2 CB750 90-125km each to test how the oil will affect gearbox and clutches after zinc additive added.
They had only idled for ca 10-15 minutes to mix the additive in oil.
Next oil changes will get zinc added in a 5L jar with 3L oil before change.
The motorcycle oil that work with modern bikes with catalytic converters has around 800-1000ppm zinc or even less.
See API classifications and oil specification of actual oil.
Our old bikes need more. I have earlier used Red Line or Spectro motorcycle oils as is or mixed as an additive.
Now other motorcycle oil with less zinc I found a hopefully good additive for.
