OP has asked more or less the same question I joined up to ask about: Is it worth having a shop do the belt or is something I can do myself? Usually I wouldn't hesitate to do something like this myself, as it seems relatively simple, but my ST is my only motorized way to work (12 mile bicycle ride round-trip otherwise) and I'd be more comfortable having a mechanic assume the responsibility if it goes wrong. Is it simple enough that I could tackle it myself in a couple days? As an idea of my mechanical experience level, a fork seal change and brake bleed on an 83 Honda Magna V45 is probably the most complex task I've so far completed but I'm fairly familiar with the workings of the engine, cooling system, etc, and I'm currently in the process of replacing at least one of the top ends for that bike, so I don't shy from tough projects. Given that, is it a low-risk project for a first-timer? If something goes a bit wrong I'll be all right cycling for a couple extra days, but a serious mishap leaves me with TWO grounded rides and long, cold ride to work. I hope this will stay in line with the what the OP wanted to get from the thread. If not I can start another. Thanks all. Looking forward to talking and learning from you.
