I am a mechanical novice and it went fine on my 2011 DL650. I just took my time, kept everything organized as I pulled it off and took pictures along the way of how it all went together. I also have the service manual, both printed and on my laptop, which was useful in the garage. There are some excellent Youtube vids by 'Dr V-Strom' on how to remove your fairings and gas tank if you have never done it before. I took my time and was very happy with how smooth it went.
Here's what I can remember from doing this job:
>Order a replacement stator and
gasket. Gasket's are pretty easy to source and I bought a used stator off ebay rather than a weak aftermarket one or wait for a seriously backordered OEM replacement (no longer backordered)
>Take all the fairings off - keep all these together and you can even label/number the screws/fasteners if you forget where each one goes.
>Take the gas tank off - simple to do - follow the steps in the manual and/or watch the youtub vid on it. Note: an empty gas tank is easier to lift.
>Take the front sprocket cover off and the stator cover off. The old stator cover gasket is like a thin cardboard gasket and can be really caked onto the stator cover. I used a sharp exacto knife to remove it and others have used an emery cloth or acetone. I had read that if the bike was on a centrestand, that only a few drops of oil would drip out when removing the stator cover. For me it seemed closer to 300ml (perhaps my garage isn't totally level?) and I wasn't prepared for it so it made a good mess of my bench and garage floor. I would suggest having a small dish handy to catch any oil that drops.
>Remove the clutch mechanism by the front sprocket and keep off to the side or remove entirely. If it's really dirty with grime and gunk, then now would be a good time to remove it and clean it all down with a toothbrush and some cleaner. The clutch actuator has tiny ball bearings inside, so when you remove it, place it in a small dish while you are cleaning it. If any bearings fall out, it's no biggie, just finish your cleaning, put them back in and put some grease in there to keep them in place while you reinstall.
>Follow the instructions in the manual on how to adjust your clutch, since you are here already. Very easy to do and see the links at the bottom for more.
> You may possibly need remove the airbox to get at the stator wiring - I did not and was able to squeeze my slender digits into the tight spaces needed and unplug, then plug the connectors. I ended up cutting a small piece of an inner fairing plastic that seemed the be serving no purpose whatsoever and preventing the connector from being easily fished out. This made the removal and re-installation a breeze. At the very least, use the opportunity to replace your air filter or at least clean it, since you already have the gas tank off.
>When putting it all back together, it would help if you used a thin adhesive to keep the gasket from slipping off the cover as you slide it all back on the bike. I didn't use an adhesive and it was a little finicky to get it back on so that all the gasket holes properly lines up with the stator cover holes.
Overall this was a great learning experience and totally suitable for a novice if you have some simple tools, a few good resources and some patience. This would have probably cost me a few hundred dollars to have a shop do the work, but I bought some tools instead and did it myself.
