So I decided I needed a new project. And why not start with a $400 2001 xc200? The bike needs a ton of work obviously. It didn't start when I bought it, but a couple of new carb jets and it started right up. The bike sounded ok, but after a couple of minute of running the engine shut off and the kick start was really hard to push down. Turns out the lower connecting rod bearing was starting to lock up. Oh well... So I'll post updates as I go. I still need a few more items to put the engine back together. It should be a fun winter project anyway.

Just did the same thing for my son's 200. While you are in there you may want to consider replacing the other bearings in the trans.
I believe these are the correct transmission bearings but double check against what is in your trans. Bearing # Counter shaft bearing 6305C3 Countershaft Seal 30x40x7 Clutch bearing 6205Zc3E Trans shafts 6203c3 98-02 Crank 63/28c3 |

Great find! Good thing you found it first.
Quick tips- Crank nut on the water pump side is reverse thread. YZ Flywheel puller is a perfect fit. And Bob Piper at North Tahoe Motorsports will hook you up for all of your hard parts and any tech data you need. Good prices, fast shipping, and good guy. Here's a link to one of his ebay ads- http://www.ebay.com/itm/TOP-END-WOSS...45baf2&vxp=mtr Drop him a note to see if he has 200 stuff, I would think he should. Also, the only thing different from the 200 to the 250/300 is machining of the cases, crank, and top end (including jug). The chassis are the same, if you didn't know this already.

Phil - Are you sure about the crank nut being left hand thread? I did a 2002 and a 2004 EC200 recently and I could swear the clutch side crank nut was a traditional right hand thread.

On my 2002 300 it was reverse thread. Lefty tighty and righty loosey. Of course, an initial inspection of the lead-in threads will tell the story, but I am certain that the primary nut is reverse.

Well... I got the crank rebuilt with a cr250 rod kit. Then I ordered a truck load of parts. I put the crank bearings in and bolted the cases together. The transmission would only spin a 359 degrees and then lock up solid. So I figured out why the bike was parked. The secondary pinion has a tooth that is about to fall off. So I still need to source another one of those. Other than that gear, the bike would be running again. Oh well. Let me know if there is a used gear I could purchase. This bike project is running over budget.

You will not be able to ride it very far that way.

Well, no one in the world seems to have one of these gears. If anyone know of one, please let me know. It is part number: ME25636076
