I picked my 06 XC up from a member here in June of 2017. It was well used and well loved, but not running and drained of fluids. The valves had run out adjustment. I paid $1300 for an 11 year old bike.
It needed valves, guides, a new rocker arm, a good carb clean, and a lot of other little things. There was a little bit of a learning curve working on an RFS engine, but it's really a dead-simple design.
The thing about a cheap bike (still a sexy, fire-breathing dragon) and an old truck is that if all else fails I can just walk away and let it rust on the side of the road.
I didn't have the time to ride a much as I wanted but I got out every chance I had.
I left it running without the fan on in my shed a couple summers later and forgot about it for about an hour. Not my finest hour. It blew the hoses and damaged a bunch of plastic and rubber parts, but nothing else mechanical was harmed. As annoyed as I was with myself, I was impressed with the bike. I fixed it and rode it, hard.
I rebuilt the shock because the bump stop was falling apart and it had lost it's nitrogen charge. The preload nut had seized and I tore up the threads trying to get it apart. I ended up ordering another shock that needed a rebuild and I Frankensteined the two together. I also cleaned the oil seals in the forks and changed the oil. I'm still on the fork seals that were changed just before I bought the bike.
After a big bend ride ride last year I was blowing a little blue smoke. I thought it was time for a piston so I ordered and installed a piston and valve seals. It was definitely time for the piston, and I picked up some power, but my smoke was due to overfilling my oil.
Last September, I was just starting to prep for a crazy ride I want to do in big bend when I crashed into a pine tree at 20mph in the forest. I squashed the exhaust and right rad flat to the frame. I also broke by thumb and picked up a nasty concussion. I was pretty sure I was going to give up riding.
I sold some backup gear and my buddy bike, a KLX250S. As it was riding away in the back of a strangers truck I realized that the next step was to fix the KTM and sell it or part it out.
I couldn't do it. It means too much to me. So, I ordered some parts on ebay and got it going again.
I took it out for a little 200 mile blast last weekend and it's better than ever. It pulls hard and is like riding on a stiff cloud with a chip on its shoulder.
I can't imagine ever getting rid of this beauty.
