I was wondering with what sort of ease someone could replace an alternator on an sr125. I figured simple bike, can't be impossible. Am I completely wrong? I have little experience when it comes to any sort of electrical maintenance.
Thanks in advance.

You'll need a flywheel puller for that bike and an impact driver at the very least. It shouldn't be too difficult once you have the proper tools.

Thanks for the reply, do you know of a place to find a guide to help me work through it as I don't really know what I'm doing. I mean is it worth me learning or should I just take it in?

That depends on IF you want to learn or not. The tools are expensive but then you'll always have them, the puller is around $15 and the impact driver is around $20 for a decent one and I highly recomend buying a decent one. The cheap ones work but won't last very long. Buy a shop manual on your bike, it's worth the money. I recomend the Yamaha one though they are on the expensive side. Clymer and Hayes produce manuals for bikes and they are almost as good as the factory ones. You can pick up the puller, impact driver and manual off Ebay or just do an internet search for SR125 manual. It shouldn't cost too much for labor if ya decide to take it to a shop, it's the part that's gonna cost.

Thanks for the help. I'll make a decision off that then and look at some prices. Thanks again.

The SR125 is available in the UK and not in the states and just how ya word stuff. The UK is cool.
