I hate carbs, and fuel injection, I just want stuff to work with no problems. Ride along the motorway perfectly, climb a mountain pass to 3000 meters with no hiccups, back down, tick over at traffic, I don't need a personal relationship with my fuel system.
Every time I did carb stuff on the XR it took ages
Having said that, last time I put the baffle back on and adjusted the air screw for it, it did feel rewarding. Don't want anymore, though. I do wish I was the kind of guy that confidently does that, but I don't think I am.
