I have to completely disagree here. if you're paying someone $100/hour, you should not be paying them that rate based upon the type of bike, but based upon their skill level. Since you say a KLR is a simple type bike, it stands to reason that what might take 6 hours on a 1200RT should only take 3 hours on a KLR. But just because the bike is 'simpler' doesn't mean the mechanic needs to be 'simpler'. He should just be able to do the job quicker.
