STVA Shaft Lubrication
The low speed idle circuit on my 2005 650 is not working properly and I will delve into the adjustment procedure soon with a multi meter to check the TP voltage as per the workshop manual.
I saw a Youtube video from a British rider who fixed a seized STVA shaft with extraction, cleaning and coating with rubber grease. He used rubber grease because of O rings in the assembly and did not want the seals to swell from using petroleum grease.
I am sure my butterflys and shafts are rotating freely as there is no error code and the only symptom is low idle speed on cold start.
If my shafts turn freely as expected I don't want to remove them but wonder if a squirt of silicone spray where the shaft comes into the throttle body throat would be of any use and if it would have any affect on the O rings if it travels that far along the shaft
