1100, sizeable first bike, I had enough DIY when I was younger, mostly on cars, what did I learn, I'm not a pro mechanic and I can't afford more than basic tools don't see much sense in buying a tool, only to use it once
after I was licensed in my professions (land surveying, onsite wastewater disposal & wetland scientist) I could make more $$ doing what I do, than the dealer charges for service, I also found that the dealer was willing to barter for my services, I'm retired now, they still give me 15% discount on parts & labor, gear, VP 50:1 premix for my chainsaw
something I learned from the mobile mechanic that did the first 50 service on my new tractor, on all the new filters with a paint pen, wrote the date & tractor hours (on vehicles with an odo, mileage instead of hours)
