There are a lot of variables, your experience, other problems that might turn up, how good of a job you want to do. Unlike professional mechanics, I NEVER set time limits on a job. I want it done right, and I want to enjoy doing it. Fortunately I have enough vehicles that if one is down for a while (my GL1200LTD has now been down at least 2 weeks now, with fuel injection problems, while I make unavailable parts and wait on ordered parts. I'm expecting it to be at least another 2 weeks) I deal with time limits and quotas enough on my regular job, the bikes are a hobby.
