An ORK would be nice but, like others have noted, I LIKE wrenching on stuff.
Taking the pipes off gives me something to do while I wait for the oil to drain.
Unless I break an exhaust bolt, dropping the pipes is not a big deal.
If I figure it takes an hour to change the oil, and I bill my time to myself at $25 an hour... I can change the oil 10 times for the cost of an ORK. By the time I put that many miles on this bike, I will probably be looking for a new bike anyway.
