Love the meeow comment...! Let's avoid the KTM vs Yam debate on here... I haven't done any tinkering with this one other than cosmetic stuff like fitting the bashplate and bars etc. I also took quite a few external parts (footpegs, exhaust etc) off when I bought it to clean them up, and that was very straightforward. No need to get behind a radiator or fiddle about in difficult spots. I'd like to do up an old Ténéré at some point and there's loads online about how simple they are. The website I mentioned above is a good place to start.
