I picked up this 2001 KLR650 with 29400 miles locally, PO said it had a diagnosis of an engine bearing needing replacement (earlier thread here). Got it running the other day and now want to address the engine bearing question. The engine is noisy, but this is my first KLR so I'm not sure what's good noise and what's bad noise. So....youtube video time! http://www.youtube.com/watch?v=24n-MDVmxpM What I've done: -changed oil -changed coolant -checked oil screen (clean) -changed brake fluid -replaced front brake piston seals -replaced bulldog'ed oil drain plug with cool low profile magnet plug -peeled off rhinoliner from plastic body panels -left rhinotank in place ;-} -cleaned carb with bucket of gunk (twice) -replaced petcock diaphragm (p/n 43028-1033) -upgraded subframe bolts -checked valve clearances, all in the middle of spec -changed front and rear tires Not sure if the above info will help, but rather have too much than the reverse. Took it by my neighbor who has more engine experience than I and he said it sounds like a metal on metal noise that may be a spun bearing. I understood a bearing might need a replacement when I got it, and it was factored into the price. At this point I'm trying to confirm that diagnosis and figure out a plan of attack. My thoughts are: 1. Drop entire bike off at my local mechanic 2. Take engine out and have local mechanic/other pull bearing(s) 3. I attempt to pull the bearing(s) I'm reasonably confident in my ability to take the engine apart, determine that it's too big a job and then go with option #2. Since the case would be cracked it would be a perfect time to throw a hop up kit in there (685, 705, whatever), but I'm leaning towards getting it running and then playing with it. Anyway, your feedback is appreciated. Thanks!
