I do all the work on the gf's Suzuki S40, but she was away from home recently and the fucking clutch cam snapped, the bit that presses the clutch pushrod. It cost her $240, I could have fixed it for $10. It's like the lights though if you don't know how to do it, then you have to pay someone.
I hate bike mechanics in general they are lazy fucking tools. They took the fucking clutch cover off and they didn't even inspect the cam chain tensioner which is notoriously bad design on this bike, if it pops out that's $1500 damage right there. I already have purchased a modified cam chain tensioner from someone in the States, ready to replace.
Now because they didn't check it which just meant looking at it. I've got to do all the work they charged her for again anyway. I hear you about building your own, but I don't have that knowledge yet.
