I was wondering what was involved in the maintenance of a 620 monster ? Specifically the fancy desmo valve system. I am an ASE automotive mechanic and was wondering if there were any special tools involved or if I purchased a shop manual if the maintenance would be pretty straight forward ?Is there a need for any type of scan tool to set timing or injectors or stuff like that? I am new to motorcycles and would like to try to cut some of my maintenance cost. BUT, I also know the value of a good mechanic who works on the same system day in and day out.Any input or suggestions would come greatly appreciated.
