    Just for completeness, I eventually parted mine out at about 75000K, engine was still OK, did a top end rebuild with High flow head and clutch bearing upgrade at around 65000 just as a precaution.

    Parted it out because seals and shit were going because I didn't ride it all the time and it spent a lot of time in the shed and I wanted to raid some of the parts for my 525 that replaced it.

    Had this bike over a year, should probably add.. fwiw it's a lot of fun off and on road. I would pile more miles on it but I also have an xr650r; both bikes get pressed into long distance dirt duty. It's a great hill climber!

    Well, thanks!
    I believe I'm on to 13, 14k? Couple of leaks but nothing major! Bike's seen a lot of interesting places. 20160716_100456.jpg 20160626_153226.jpg 20160706_195805.jpg
