Greetings! New member here. Big Island, Hi. Just picked up an 09 klr650 and only have a few service notes in the owners manual as a history of what has been done to it. It has 33k on the odometer with a note of engine rebuild at 18k, there are also 705 stickers on the side covers. I pulled the alternator cover off to see if the doohickey has been upgraded but realize I will need to get a special tool to pull the alternator rotor off. Question # 1- I can see the bottom of the doohickey is there any way to identify it from that alone? I will be replacing chain and sprockets with new nut and locking washer for front sprocket. I also notice that the crank case ventilation hose has no pcv valve and is directed out over the rear swing arm. The fitting at the bottom of the air box where I assume that hose should go to is just open. Question #2 - Is that a common mod or do I need to correct something? It seems important to have the vacuum of the intake drawing out the gasses. The other notes in the manual indicate regular oil changes. I have lubricated all control cables. Question # 3- Are there any other things that I should have a look at? Bike runs really smooth and solid. Thanks a bunch.
