So about 2 months ago I decided to trade my 69 Cj5 for a 2001 KLR 650 to pursue my passion of riding. I have followed advrider before I even started to ride full time and love the people and the site. (little bit of background) It's funny because yesterday I learned all about the darn "doohickey" problems... and decided to change it as soon as I had the money. But today I took it out for a couple of trails and ran into a problem. I was in first gear going through some steep short woops and heard a sound coming from the casing and stopped, it sounded like another idle coming from the engine if that makes sense and the bike itself was a little rougher. I shut it off, checked fluids, all was good there. I wasn't to far from home and decided to ride up the last hill and could coast down a powerline road to my backyard. As I started heading up the short hill of woops the bike stalled going down the backside of a woop. I tried to start but it wasn't even trying to turn, thought the battery might of died and tried to jump but the back tire was locked. I have a bad feeling I seized the engine. What do you guys think?
